Changing the differential fluid is something that's often overlooked. The best rule of thumb is when you change the transmission fluid or gear oil change the differential fluid too. But if you have a truck and you are loading it down it's a good idea to change the fluid more often.
Be sure to use the right fluids. Some manufacturers use special fluid, especially in the transfer cases. Like certain Hondas. In our fleet, we have an 07 Ridgeline that takes a specific fluid for the transfer case, since it is AWD. Major damage can be done if the wrong fluid is used, so always follow the recommendations in your owner's manual. And I highly recommend buying the exact fluid from the dealer. Yeah, it's more expensive, but not as expensive as replacing a failed unit because the wrong fluid was used!
Just did this in our 2012 Rav4, so easy. I was $65 all in (had to buy a different allen wrench that could fit into the front fill plug, used Mobil1 75w-90, and a really simple pump from Advanced Auto) and it took about 1 hour. Local shop wanted to charge $296.
I'm 70 years old and for the first time in my life, the Tacoma truck I bought in 2012 is worth more than I paid for it brand new. Has 72,000 miles on it and I had to replace my 80,000 mile Dunlops because of dry rot not because the tread was worn out. I know it doesn't need a tune-up yet, but 13 years old is 13 years old.
@@isaacainley5876 Do you drive a lot of miles on cheap tires? Or do you have the low pro thin tires? My Michelin tire guy told me they wear down fast and are expensive. I would have bought a Toyota Venza, but it had low pros, so I passed. Looked easy to bend a rim.
My 09 Honda has a crappy front end and a little rust, but it is paid for! Made in Canada, shifts like a dream and well taken care of!!! Been driving it everywhere, almost from day ONE of finding Scotty's channel....back when he had only a couple of million subscribers. Scotty is THE MAN!
New vehicle manuals suggest mileage intervals to change oil and or coolant and or transmission fluid are to long between changes that I usually halve the mileage recommended. Bought a 2017 Toyota Camry XLE in 2021 and I completely went through all the fluids and changed them all. Even the brake fluid which was fairly clean but I wanted to bring my car up to date with me as a new owner.....starting fresh. The Michelins that came on the car were OEM and the fronts were pretty much done when I got the car with 27k miles.... inspectable but.......drove with them through the summer and fall. So that tells me the previous owner never rotated the tires......so I bought a new set of 4 tires plus an alignment just before the winter months. My car drives like a dream......smooth as butter.
I do not recommend using a 5 gallon hard plastic water jug to hold your oil. Have you ever seen those things crack? They're not very forgiving. Laundry detergent containers are the best. You could throw that thing out of your truck while you're driving and it would be fine. But the plastic water jug is asking for trouble. 😮 🤦🏻♂️ 🌊 🤸🏻
Good that he mentioned about the tires. Of course, most people won't believe it. That's ok, because I make a lot more money off of replacing AWD units than I do from tires...
I'm a native of the Az desert and have had 4x4's most of my life. I had mentioned this to a friend who bought his 1st and he didn't listen and couldn't get it loose after draining it. I also mentioned that he should at least run the 4x4 units once a month for about 10 or so miles to keep the seal's from drying out because it could cost good money if they start leaking and it doesn't take long with our climate to dry out the seal's.
In some vehicles, like mine, the front differential is always turning but not under load. I'd recommend to just change them both at the same time, along with the tranfer case fluid (In mine it's transmission fluid), in most cases it is. Use whatever spec & fluid type is recommended by the manufacturer
@@JamesFlynn-np7sq really appreciate the answers but sorry for my lack of knowledge as I never understood the difference between transfer case oil and the rear differential oil? (and yes i only use what the manual specifies always)
Here’s a tip. Don’t forget to use Teflon tape on the drain and fill plug threads. It makes it a whole lot easier to get those plugs off again. I never had any of them back out even with anti-seize compound on those threads. They were even worse to get out with the old differentials that used a 3/8 square that fit a 3/8 drive ratchet.
I would bet that 95% of drivers never change their diff and transfer case fluids. If you buy a car new and only keep the car a few years this will probably never become an issue for you. However, if you buy used cars, it could cost you. Whenever I have purchased a used car I always replace all of the fluids right away just in case the fluids have never been replaced.
My husband and I are going to buy the last vehicle we'll ever own since we are in our upper sixties. we want a small suv . We thought about rav4 but you said new are not the best.I really appreciate your help
I've been doing this for my niece's CRV. Started at 55000 miles and doing every 50k-only down side is you have to use the Honda Dual Pump 2 fluid and its not cheap!!!
I changed both front and back diff.on my Jeep WK2 at 95k miles. I bought it used because it was such a clean vehicle, figured it could only help. The fluid on both came out looking brand new. Jeep calls for every 60k miles.
Same, I have a 2013. Ford really stuck it to us with that rear diff. I was only able to get about 1 pint out but it took a full quart to fill. Also nice job Ford for having the factory fill extremely low.
After my 2001 escape needed a new engine, I bought a 2007 jeep patriot at the ford dealership. It was about a year old with very low mileage. I bought a 5 year extended warranty from the dealer to cover me while I was paying off the loan. I had the car for about 3 and a half years when my right wheel went out. I took it to a dodge dealer and presented my warranty for payment. The dodge service rep called and told me my warranty had expired. After calling the ford people, they said evevthough I I purchased the warranty, it was activated when the car was first delivered to the dealership. In essence, I paid for a 5 year warranty that began over a year before I purchased it. I was sh*t out of luck. I had to pay out of pocket. I will never bu a warranty again. It's just like you said, these are insurance policies, and there isn't anything more crooked than an insurance company!
I understand the replacing of all 4 tires so they are the same size, but why is ok for the AWD system to drive on unevenly worn tires? I'd think having the front to rear so different wear wise would also damage the system the same way replacing only the front would.
Scotty thank you so much for your sharing of automotive information. You have saved me a lot of money. Wish there were more truthful mechanics like you. God bless you and your family.
I'll tell ya another trick... When I put differential fluid (in which every vehicle I ever owned) I'll put stop oil treatment in with it also (never put in motor) makes it so slippery in there you WILL notice a difference! And especially in a standard transmission... Makes the gears slide in shifts so nice. I've done this every one and haven't had a problem. In fact guy I knew his truck once sounded like the rear end was gonna fall out.. drained the old out filled it with stop oil treatment only.. it quieted down and he still drives the truck to this day never changing a anything.
Scotty, do you ever do any repairs or maintenance inside a shop or garage ??? Always in the driveway? I’ve been a shop owner/mechanic for over 30 years and I have no desire to roll around on the ground. Great work btw. Knowledge is strength
like my mechanic friend, retired from workshop as he developed dermatitis from the grease and oil contact. Yet he would do it for friends at his home's driveway. He would probably do 1-2 jobs a week.
I change my fluid on both differential and transfer case. On a 2012 Highlander. 1 yr after the rear pass tire lock on the highway at 55mph, they both went bad. Milage 116,000. I do believe after pass 100, no more changing fluids.
I have a five year old 4X4 Isuzu 3.0 liter diesel. It only gets serviced at an Isuzu dealer. The last time I got it serviced the mechanic asked me to look at the coolant. It was nearly clear. He said that when the coolant loses the color, it should be changed. The coolant wasn't that expensive so I had it changed. My Isuzu is the best vehicle I have ever owned. No problems at all and it still looks like new. It is more economical than my wife's gasoline car with a tiny 1.5 liter engine.
I have never owned a car that had a drain plug in a differential or transmission! I have to pull the pan or cover to drain them. And have owned 86 cars in my life.
I always buy the Platinum Extended Warranty thru Toyota Canada. The most years and kilometers they offer. The Platinum covers almost everything except wear items like brakes, tires, wipers. I feel it is cheap insurance in case something goes wrong. There are alot of electronics on today's cars and with the salt usage in Canada something is bound to go wrong. 2009 Toyota Rav4 V6 had to get 3 driveshafts to the rear replaced. That paid for the warranty in itself. 1st failed just after regular warranty. 3rd failed just before Extended warranty was up. Of course this is my opinion.
Subaru has front and rear differentials. The transfer case is integrated with the transmission. How often should the fluid be changed? The manufacturer recommends changing at 30k miles for severe service but no change interval for normal service. I did transmission and differentials at 60k.
Please listen to what Scotty says here. I had the misfortune of buying a 2011 Toyota Venza V6 AWD used. I bought it with 80,000 miles. At 83,000 miles, the rear differential completely went out. As it turns out, the previous owner never maintained it. $5500 later, I had a new differential. That was 20,000 miles ago. Everything is great now, but you better believe that come 110-115,000 miles, that differential will be getting new gear oil. Maintain your vehicles, folks.
Everyone needs to change their old gear oil at least once to experience a truly "unique" horrible smell!!!! A horrific rotten sulphur base odor with notes of burnt citrus and flesh
this would be my next level of challenge. I can do my engine oil and filter quite well now. Mine is a 2006 Highlander. Wonder what type of washer I should get.
How is it that the tires are already different size (as the fronts are severely worn) and it hasn't ruined the all-wheel- drive system ? Why wouldn't putting two new tires on the back and moving the back to the front be be the same or better than the current setup ? Your premise makes no sense.
I like using the Motul 300 75W-90 GL-4/GL-5 gear oil in both my 6-speed gearbox and differential on my 370Z. I top off the levels at 10k mile intervals and change it at 20k miles. The Motul is a GL-4 and GL-5 API certified oil that has extreme pressure wear protection for hypoid bevel gears on differentials but doesn't use harsh sulfur and phosphorus compounds that can be corrosive on soft metals and seals. The Motul is more expensive but it does perform very well, especially under high temperature, high rpm use.
Just changed the manual gearbox oil in my mondeo...pig that was to do, lca and subframe in the way, but i did it Scotty. Whoop whoop🎉🎉 used an hex/Allen key inserted through a spanner to tighten everything back. Not much space for anything else. 15 year gear oil that came was junky black and dirty.
No.. What you do in that situation is put your front wheels on the rear, and put those "good" tires from the rear- onto the front. Since your front wheels do most of the braking and nearly all of the pulling while driving; plus they wear from turning too-- they get worn much quicker than the rear. Those rear wheels just drag behind like a trailer axle 90% of the time.
Bought a used 2000 CRV 10 years ago. It was making a bad clicking noise in the rear going around corners. Changed the rear diff fluid and noise is gone. Currently 212,000 miles with no noise.
Hello Scotty, Great stuff! I particularly love the fact that you advise your huge audience to crack the Fill Plug first and then the Drain Plug! I have witness so many mechanics make the mistake of draining a gear box before they ensure that they can fill it! LOL 😁😄😃😀😆😅😂🤣 Chuck Whigham
Cracking open the fill plug also allows the fluid to drain better. Allows some air in as the fluid drains out. But yes check to see if you can loosen it first. That would suck if you cant get the plug out. Also make sure you use the correct sized hex as well. Don't strip it. Also if its tight tight bump it loose with a rubber mallet, not a steel mallet.
Best recommendation is too check the fill plug before you remove the drain plug. You only have to make that mistake once in your life to learn. The rest? Maybe worth it if you have a simple vehicle with easy access to the rear diff.
The higher the mileage, the higher the number of the oil or fluid. Dont put 75/90 thinner oil on an old 150k plus gear or transmission. They are worn out inside gears. Use thicker oil on old thinks. Think.
Been wrenching on my own cars, bicycles, quads, motorcycles my whole life. If you know what you're doing you don't need a torque wrench, just get it "nice and tight"
If you have a manual transmission, it's the same process as a transfer case or rear differential fluid change - only the type of gear oil is different.
Same with manual transmission fluid. It's not a lifetime fluid and it should be changed accordingly. In my Accent all it is are two 17mm bolts and two bottles of proper Gl-4 rated gear oil. "Proper " is a key word here because there are many grades of it. Owners manual has all needed info.
Should I be worried about my diff? I changed the old fluid when I bought it and about 8k miles later I decided to check the fluid and instead of being gold color it was dark and on magnet was lots of grey mush… I’ve been putting my hand on the cover and it takes about 3 seconds until it starts to hurt from the heat… is it running to hot and wearing out? I just feel like the gear oil shouldn’t be dark yet because my front diff fluid is still golden looks like nee
How can you say four tyres have to be bought together to keep all four wheels the same diameter? The front tyres clearly wear more quickly than the rears so they'll soon be a different diameter, which you say is unacceptable.
You rotate your tires every 5000-10000 miles. Keeps all the tires the same...until, hopefully, they all wear out at the same time. The issue is when you have 50,000 miles on a set that has 20,000 miles left, and you blow a sidewall out on one tire! You have to replace all 4. That happened to me on my 2016 Legacy.
Scotty .. Still doing oil changes when he really doesnt need the money . Scotty mentioned an Important Tip about loosening the Fill plug first BEFORE you drain it .
Just bought a 4th gen 4runner and the people were meticulous about maintenance. Every two years they would do the service Scotty shows here plus front and rear diffs. Simply amazing!
There's no such thing as lifetime fluids, regardless of what the manufacturer says. I change my manual gear oil every 15/30k , change my brake fluid every 80k, change my coolant every 100 k
Learned a lot from Scotty over the years. I’ve always had old cars eg, had to give up my 04 crown vic last year (2022) at 236Kmi it was a great car. Still have my 07 Camry CE w/ about 171Kmi. Easiest maintenance schedule for me is always using synthetic fluids as applicable and changing oil/filter, air filter, cabin air filter, tire rotation at every 6Kmi; this includes checking the battery cell fluid and adding distilled water as needed (my batteries always last at least 4-5 or more years). Then change at every 30Kmi all fluids including also steering, brake, radiator, and transmission - and now these transfer cases on my new 2022 AWD CRV. I’m also anal by tracking all this in an Excel file.
I will never buy an AWD, RWD or 4WD again. I have had the driveshaft bolt back out on two cars. In the 5 years I have owned my 2002 Toyota 4Runner, I have engaged the 4WD for 10 minutes. I live in Michigan. Just not worth the headaches. So many more parts that can fail.
My 2011 AWD Durango is leaking from the transfer case and transmission fluid but runs and drives fine I’m i in trouble yet ? 👀 w/ 200,000 miles though…
what about cars that have 4WD but almost never use it, does not changing the rear differential still cause damage since its not being used? Also does it matter if it is front wheel drive or rear wheel drive?

Hey Scotty, can you check the mileage on a used car with Bluedriver?
Scotty, must you take the Lord’s name in Vain?

Scottykilmer why do you always work on Toyota? You are a Yank, work on Mustang, Camaro, Challenger or Charger.

And it’s not lifetime. Do it at 60 K.
And dispose of it in a non-jerk way. Burning it in an old pan outside is fine if you live in the country.

He said that when the coolant loses the color, it should be changed. The coolant wasn't that expensive so I had it changed. My Isuzu is the best vehicle I have ever owned. No problems at all and it still looks like new. It is more economical than my wife's gasoline car with a tiny 1.5 liter engine.
On all wheel drive vehicles no one replaces all 4 tyres in Australia.
You have to. It'll wear out the transfer case or tranny..unless you have the same exact tires..then yu might be able to get away with it
Scotty is the best mechanic teacher on the earth and youtube!!
Yup i change all fluids in my 2014 ford f150 every 60,000km runs like a dream ❤ oil changes every 5000km
I have never owned a car that had a drain plug in a differential or transmission! I have to pull the pan or cover to drain them. And have owned 86 cars in my life.
I always buy the Platinum Extended Warranty thru Toyota Canada. The most years and kilometers they offer. The Platinum covers almost everything except wear items like brakes, tires, wipers. I feel it is cheap insurance in case something goes wrong. There are alot of electronics on today's cars and with the salt usage in Canada something is bound to go wrong. 2009 Toyota Rav4 V6 had to get 3 driveshafts to the rear replaced. That paid for the warranty in itself. 1st failed just after regular warranty. 3rd failed just before Extended warranty was up. Of course this is my opinion.
Subaru has front and rear differentials. The transfer case is integrated with the transmission. How often should the fluid be changed? The manufacturer recommends changing at 30k miles for severe service but no change interval for normal service. I did transmission and differentials at 60k.
scotty I did this on my 98 frontier Nissan four wheel drive, also a stick as well. great mileage improved
I had a hard shifting problem in my auto trans, changed fluid and filter, smooth as silk now
Please listen to what Scotty says here. I had the misfortune of buying a 2011 Toyota Venza V6 AWD used. I bought it with 80,000 miles. At 83,000 miles, the rear differential completely went out. As it turns out, the previous owner never maintained it. $5500 later, I had a new differential. That was 20,000 miles ago. Everything is great now, but you better believe that come 110-115,000 miles, that differential will be getting new gear oil. Maintain your vehicles, folks.
Everyone needs to change their old gear oil at least once to experience a truly "unique" horrible smell!!!! A horrific rotten sulphur base odor with notes of burnt citrus and flesh
this would be my next level of challenge. I can do my engine oil and filter quite well now. Mine is a 2006 Highlander. Wonder what type of washer I should get.
So running overly worn front tires with less worn rear tires hasn’t already screwed up the AWD system?
I assuming this is the same process for a Mazda CX5 which is all-wheel drive more or less. Love your videos BTW Scotty -- very informative!
How is it that the tires are already different size (as the fronts are severely worn) and it hasn't ruined the all-wheel- drive system ? Why wouldn't putting two new tires on the back and moving the back to the front be be the same or better than the current setup ? Your premise makes no sense.
My neighbor did this for me last weekend. It was black toxic sludge. I've heard people say it's good for life, but no it's not.
I like using the Motul 300 75W-90 GL-4/GL-5 gear oil in both my 6-speed gearbox and differential on my 370Z. I top off the levels at 10k mile intervals and change it at 20k miles. The Motul is a GL-4 and GL-5 API certified oil that has extreme pressure wear protection for hypoid bevel gears on differentials but doesn't use harsh sulfur and phosphorus compounds that can be corrosive on soft metals and seals. The Motul is more expensive but it does perform very well, especially under high temperature, high rpm use.
Watched a UA-cam about 5 things good mechanics do. Loosen the fill before you drain was on the list. There’s Scotty showing off how good he is
I had a VW that had a 19mm Allen screw in it, Had to go buy one, guy at the auto parts store knew what year my VW was, 1972 Super Beetle.
So your saying with an awd vehicle if you pop 1 tire with a pothole you need to buy 4 new tires instead of just the 1 that popped ?
Thank you for the RAV4 AWD knowledge. So many of us are driving them, trying to keep them on the road.
It's for any awd.....because some people want a honda,or another awd
Just changed the manual gearbox oil in my mondeo...pig that was to do, lca and subframe in the way, but i did it Scotty. Whoop whoop🎉🎉 used an hex/Allen key inserted through a spanner to tighten everything back. Not much space for anything else. 15 year gear oil that came was junky black and dirty.
Great advice as always. Scotty, you should stay longer, leave in August, it seams you just got to RI. 😊
No.. What you do in that situation is put your front wheels on the rear, and put those "good" tires from the rear- onto the front. Since your front wheels do most of the braking and nearly all of the pulling while driving; plus they wear from turning too-- they get worn much quicker than the rear. Those rear wheels just drag behind like a trailer axle 90% of the time.
Bought a used 2000 CRV 10 years ago. It was making a bad clicking noise in the rear going around corners. Changed the rear diff fluid and noise is gone. Currently 212,000 miles with no noise.
Hello Scotty,
Great stuff! I particularly love the fact that you advise your huge audience to crack the Fill Plug first and then the Drain Plug! I have witness so many mechanics make the mistake of draining a gear box before they ensure that they can fill it! LOL 😁😄😃😀😆😅😂🤣
Chuck Whigham
really was great advice!
Cracking open the fill plug also allows the fluid to drain better. Allows some air in as the fluid drains out. But yes check to see if you can loosen it first. That would suck if you cant get the plug out. Also make sure you use the correct sized hex as well. Don't strip it. Also if its tight tight bump it loose with a rubber mallet, not a steel mallet.
Can you explain why to use a rubber mallet versus a steel one ?
Nice demonstration Scotty. I will be doing the same thing to my BEAST. Thanks for the reminder too.
Back in the good old bad old days, EP oils used to come with both a straight and cranked pipe
Rule of thumb , If you buy an extended warranty the car wont break , if you dont buy an extended warranty you'll be fixing something every 3 months.
Best recommendation is too check the fill plug before you remove the drain plug. You only have to make that mistake once in your life to learn. The rest? Maybe worth it if you have a simple vehicle with easy access to the rear diff.
I remember changing out the differential fluid in my uncle’s suburban after 156,000 miles. Compared to new fluid it looked very worn out. FWIW
The higher the mileage, the higher the number of the oil or fluid. Dont put 75/90 thinner oil on an old 150k plus gear or transmission. They are worn out inside gears. Use thicker oil on old thinks. Think.
Been wrenching on my own cars, bicycles, quads, motorcycles my whole life. If you know what you're doing you don't need a torque wrench, just get it "nice and tight"
Scotty's the man!!!! Always helping us u tuber fellars n fellets out with maintenance!!! You rock 🪨 Mr. Scotty!!!
If you have a manual transmission, it's the same process as a transfer case or rear differential fluid change - only the type of gear oil is different.
And make sure you can fill it before you drain it! Haha 🤣
Same with manual transmission fluid. It's not a lifetime fluid and it should be changed accordingly. In my Accent all it is are two 17mm bolts and two bottles of proper Gl-4 rated gear oil. "Proper " is a key word here because there are many grades of it. Owners manual has all needed info.
never changed any fluid, only added some and that since 1995 on the same car my volvo 740 from 1985
Should I be worried about my diff? I changed the old fluid when I bought it and about 8k miles later I decided to check the fluid and instead of being gold color it was dark and on magnet was lots of grey mush… I’ve been putting my hand on the cover and it takes about 3 seconds until it starts to hurt from the heat… is it running to hot and wearing out? I just feel like the gear oil shouldn’t be dark yet because my front diff fluid is still golden looks like nee
Do you need 4 jack stands to keep it level when it's jacked up?
How can you say four tyres have to be bought together to keep all four wheels the same diameter? The front tyres clearly wear more quickly than the rears so they'll soon be a different diameter, which you say is unacceptable.
You rotate your tires every 5000-10000 miles. Keeps all the tires the same...until, hopefully, they all wear out at the same time. The issue is when you have 50,000 miles on a set that has 20,000 miles left, and you blow a sidewall out on one tire! You have to replace all 4. That happened to me on my 2016 Legacy.
Brand new drain pan brand new gloves; have you ever done this before? 😂
How do you know it's new pan? And why use crap gloves for video?
@@psynurse you can't tell. Have you ever done mechanic work?
Scotty is in Texas might have something to do with how the pan looks @@Avengedsevenfoldrocks
Park it on a flat surface & then jack it up so it's no longer flat.
Scotty ..
Still doing oil changes when he really doesnt need the money .
Scotty mentioned an
Important Tip about loosening the Fill plug first BEFORE you drain it .
Just bought a 4th gen 4runner and the people were meticulous about maintenance. Every two years they would do the service Scotty shows here plus front and rear diffs. Simply amazing!
Those Dreaded TransxaxLes... Storys; Listen uP🆙 , Lol.
There's no such thing as lifetime fluids, regardless of what the manufacturer says. I change my manual gear oil every 15/30k , change my brake fluid every 80k, change my coolant every 100 k
Good for you. My 2010 Mercury Mariner never changed any fluids other than the oil. Going strong at 203,000 miles.
All-wheel-drive (AWD) vehicles need a lot of maintenance, as well.
My Subaru never did
If you take the fill plug out before you take out the drain plug ...it flows out much easier and quicker...
And I'm still not sure Scotty owns a torque wrench 🤣
What’s the difference between all wheel drive and full-time four-wheel-drive? Is there any?
My 2008 Camry only has 67,000 miles. The owner book does not show a trans fluid change until 150,000 miles. Should I do it now?
Learned a lot from Scotty over the years. I’ve always had old cars eg, had to give up my 04 crown vic last year (2022) at 236Kmi it was a great car. Still have my 07 Camry CE w/ about 171Kmi. Easiest maintenance schedule for me is always using synthetic fluids as applicable and changing oil/filter, air filter, cabin air filter, tire rotation at every 6Kmi; this includes checking the battery cell fluid and adding distilled water as needed (my batteries always last at least 4-5 or more years). Then change at every 30Kmi all fluids including also steering, brake, radiator, and transmission - and now these transfer cases on my new 2022 AWD CRV. I’m also anal by tracking all this in an Excel file.
Yes 60 thousand miles
Do to recommend this procedure to older cars?I have a 2006 ford explorer with 110k miles on it. Thank you.
Diff/trans gear oil replacement is never a bad thing.
I've replaced them twice in an 05 Highlander....get it done
I will never buy an AWD, RWD or 4WD again. I have had the driveshaft bolt back out on two cars. In the 5 years I have owned my 2002 Toyota 4Runner, I have engaged the 4WD for 10 minutes. I live in Michigan. Just not worth the headaches. So many more parts that can fail.
Look up the manufacturers recommend oil some of the newer transfer cases use Atf or a specific oil.
2:30 Am I the only one that LIKES the smell of gear oil?? :D
God, please bless Scotty and his family and all his grandchildren for all Scotty's kindness to people around the big World.
Question, I have a 2016 Ford utility police interceptor AWD 114K miles and have no police maintenance records . Should I change it .
I was honestly expecting you to tell people to clean everything up and pour the used gear oil back in...like you do for transmissions.
What Scotty still works on cars? 🎉❤🎉
75w90 or 75w85 which one is the right one for 16rav4?
Easy as pie, if you can take the fill and drain plugs, my 2011 highlander came from New Jersey and I guess they are corroded in place, any ideas??
My 2011 AWD Durango is leaking from the transfer case and transmission fluid but runs and drives fine I’m i in trouble yet ? 👀 w/ 200,000 miles though…
what about cars that have 4WD but almost never use it, does not changing the rear differential still cause damage since its not being used?
Also does it matter if it is front wheel drive or rear wheel drive?
The fluid that came out didn't look too bad. Good that they are changing it now.
