I love these kind of videos when he sits down and feels like he’s talking to you one on one. I actually finish the video knowing I’ve learned something new.
He's talking to me one on one, not you.
It's so intimate *blush*
Talk to me all intimate, Toyotasenpai
I suffer badly from anxiety and watching this guy takes me away from my troubles and all the troubles of the world.Thankyou.
Yeh, he's a relaxed calm, smart person.....try to surround yourself with people like him & avoid hyper, loudmouth, drama-queen people who are up themselves & your anxiety will improve tremendously 👍
@@mrgarrison3516man that sounds great! Where do I find people like that?!?! 😮 😂
@@steved0603
Until u find those people, become like those people & they might find u 👍
The new Lexus "full time AWD" from what I've read (latest NX and RX, not sure about other models) is very similar to the standard AWD shown in the video, except it simply uses an upgraded magnetic clutch and keeps the rear wheels at least partially driving at all times.
Excellent video on unitized awd systems. Most people don't realize that they decouple at 25 mph.
Do they still do that? I thought they stopped that with the newer ones?
Ditto
I had to show that to numerous owners that 25 mph limit, because they thought that Toyota has some kind of "high end AWD" in their "cute SUV" segment...
No Limited Slip, no central differential...
PS: I have a RAV4 too... not a hater, just realist.
i heard about that i had a coworker who had a 4x4 toyota FJ Cruiser and said it goes away after 25mph
Not all of them decouple. The earlier Sienna and Highlander systems are on all the time.
Because of You Sir and other Social Media Specialists, I purchased a 23' GX at a great discount and feel Secure/Safe . Reliability plays a huge role IMO in these times of uncertainty.
Newest tech on transportation does Not fit well for me until most kinks are fixed which can take many years.
Again Thanks for your knowledge .
PS.... Wish you had a Shop in Southern NJ😂
Another great video. You explain it so a non mechanical person can grasp it. As a past wheel/track mechanic in the army i always look forward to you passing on your knowledge. With technology the way the new cars/trucks are it is a great way to keep up from your videos.
Thanks for the very educational video! Could you do a similar video on the AWD system in the newer Hybrids?
On the Prius AWD, we have a small electric motor on the rear wheels that provides 10HP and is activated from stop up to around 10 mph then whenever the front wheels spin…works great on icy roads and up icy hills.
You don't seem to know much about Toyota and Lexus 4WD.
I believe it's been covered in several already. There's a second electric motor/generator in the rear and no physical connection to the front. Works great in my Rav4 hybrid in snow and on gravel roads. It also applies brakes to specific wheels to help minimize slipping.

Thanks for this video. Very informative and helpful.
2 years ago my 2013 Venza's coupler was leaking oil and spraying all over the back and into the trunk. I think the bearing was worn out. Dealer quoted me 4000CAD for the coupler and labour. I looked up in ebay and found a reseller from Japan . Paid 800 for the coupler. Fixed the whole thing for $1800 including labour and tax.
If it was spraying or leaking oil it was probably the pinion oil seal. That could be replaced relatively cheaply without replacing the coupler. I've read about some people changing just the bearing too.
It’s possible. I also remember fidgeting with the pressure release cap that sits on top of the differential. It was rusted but definitely not stuck. And judging by the spray pattern i was convinced it was the coupler.
I learn so much from this guy. Watching his videos inclines me toward buying Toyota products in the future, I have owned plenty in the past. I am also a Honda fan, currently driving an Acura.
This is not right, You should be on Toyota’s payroll for life… no one explains things better than you and it’s clear to understand with details… I really appreciate the time you spend on this channel… Thank you
Scotty Kilmer is our wise old grandfather Toyota loving mechanic and AMD is THE best high school auto mechanics Toyota loving teacher we could ever have. I wish he'd been my auto mechanics teacher back in high school, but super glad we have him now this way! My first video of his was his 3rd gen Prius traction battery cooling fan filter video where he very kindly and thoroughly explained the need and installation. Been watching ever since.
AMD, Thanks! You have answered questions about Toyota AWD systems that I did not even know I had. 🤩
You couldnt possibly have watched the entire video within 2 minutes of the video being posted to have all your "questions answered".
When he sits down, it’s serious 😂
Excellent video. I have a 2006 Matrix 4WD with 218,000k miles. It has the non-electronic viscous coupler that has been repaired twice: First, the larger VC bearing was replaced at 88k (sounded like a jet engine), second the VC housing was replaced at 193k (the larger steel bearing had worn out it's seat in the aluminum housing, creating play as it rotated). Also, I do a drain and fill every 30k on transmission (Type-IV), transfer case, and rear differential (Mobil 1 75w90 gear oil).
Excellent video. thank you for creating it!
Thank you for an excellent explanation of all wheel drive, that was easy for a regular person with very little mechanical knowledge to comprehend.
Thank you, this has been amazing to watch!!!!!!
Awesome video, did not know about the towing issues with all wheel drive vehicles
Thanks 🙏
Another Excellent Video. Waiting for the next one.
always learning something new from AMD, yet another super informative video, keep up the great work!
Thank You CCN. Love your vids. I can view them to the end cause you explain things properly.
Excellent commentary, love the educational value in all your videos.
I can't get enough of this channel!
I've heard about torque vectoring for about a year. I think I finally understand it with this video. Thank you!
Another great video thank you. Learnt a lot
Another educational video, Thanks AMD!
Great video, learned something new!
Great video. I have always considered AWD to be marketing noise because it can mean almost anything. It is great to see what it can mean for the different Toyota configurations.
Love videos very informative, watching it from Sydney Australia.
Well that was very interesting. Thank you Sir!
Wow, amazing and super clear explanation, thank you!
Best explanation I’ve seen! 🏆🏆
WOW. such a really cool video. Really do love your work.
I absolutely love this series. Just how the background is set with the lighting and have the actual equipment right on the table, and speaking to us like it’s a one on one
Will you ever do a video of how simply set the background and the lighting? Maybe even as a shorts?
This was great. Thank you.
Great video AMD!
Very nice video too. Thanks!
Great video AMD! 👍🏼
love your videos always so very informative. 👍
Thank you for very good information
You’re one of the most knowledgeable techs that I would even begin to listen to here on UA-cam. Your content is factual, and based on actual experience rather than theory. I can appreciate the time and candor that Troy put into a video for us viewers and other mechanics who need this type of information! Thank you greatly!
Excellent. Watched tons of your videos now - I am one of those people who used to say 'I know nothing about cars'. Well, not any more thanks to you. Thank you for your time and talent.
Another interesting and informative video. Thank you.
Another excellent video of how things work.
Thank you very much for the clearly spoken and basic Understandable instruction on Toyota Oil changes and Torque Vectoring .VG
You're videos. Just keep getting better and the lighting as well. Excellent 👍
Very helpful thank you.
We have another winner! Quality expert advice everyone loves.
Very interesting information. Thanks.
Thanks! Great Video!
Thank you very much for your excellent infromative videos👍
My 5th Gen RAV4 is pretty great in the snow. I got stuck once because I bottomed it out and the snow froze. That was totally my fault though, I'm still learning this winter stuff.
This guy is amazing, Thank you Car Car Nut Channel, keep up the good work.
Will you be doing a similar video on the 4WD, like a Land Cruiser? Thanks for you excellent videos
Thanks! I've always wondered how my AWD 2016 Lexus RX operates. Great breakdown and tips! Glad I went with LEXUS genius simplicity, quality and dependability . . .
I learned a lot, thank you!
I enjoy how you explain things.
Very informative, your vids are the best.
Excellent!
I have a 2015 RAV4, learned plenty, thank you.
Thank you, very good information!!
Great video 👍
I learn so much from watching your channel. Thank you!!!!
Thank you! Very informative!
Terrific explanation. Thank you very much
Always enjoy your videos, and have found them to be very helpful in keeping my wife’s 2014 Sienna AWD on the road. I’m going to add a comment to this video in particular in the chance it may help another Sienna owner in the future. At approximately 110k miles her van started making a very high pitched whining noise from the rear end of the vehicle. I checked both rear hubs and they were fine, so I did some looking online and found a description of the problem that appeared to match the one I was experiencing. It had to do with the bearings in the AWD coupler you mentioned in your video.
I know the internet can be a place where issues can seem to take on a life of their own, but looking through the various posts and videos this NOISE did not seem to be that uncommon of an issue on Sienna’s. As you mentioned the coupler itself can be replaced as an assembly but after seeing the price for the OEM part I decided to go the route of replacing the bearings, seal and dust ring. The parts were available for well under $200, and since I used to turn wrenches for a living a long time ago I figured I had little to loose other than some time and possibly some money making the fix vs replacing. There’s a couple of videos out there showing the process, so I watched them and then tackled the one on my wife’s van. This is NOT something I’d recommend for those who aren’t mechanically inclined, but it also wasn’t something where you needed to be a master technician to accomplish. Made the repair about 50k ago and am happy to report the noise immediately went away and my wallet was very thankful I took the chance at making the repair. Just thought I’d throw this out there for anyone who’s so inclined to repair the coupler themselves.
Again, thanks for all your videos and sharing your tremendous knowledge with Toyota products.
Good informational video , thanks I have the front wheel drive highlander . Nice too know how the Toyota AWD drives works
Beautiful video. Thank you buddy. God bless
Thank for you for the informative video on Toyota AWD system.
I really appreciate you sharing your knowledge as a more informed and better educated consumer prevents those crooked mechanics from taking advatange of us hard working folks.
We are willing to pay, if we know we are NOT being taken advantage of.
Honesty and integrity from mechanics is priceless and you are one of these dying breed of mechanics.
Keep these videos coming, I feel like you are a mechanic professor and this is how you make this world a better place by making these videos!
Excellent video 🇦🇺
Great channel!
Thanks for today's lesson.Verry interesting !
Thank you for that information you’re the best on this business God bless you
Great video
Brilliant, thank you 😊
Wow! Even though I don't have Rav4 at least I have knowledge how this AWD works and the do and don't! Thank you so much.
I was thinking about this and suddenly CCN makes a video. perfecg
Thank you AMD! I never heard the AWD system explained before.
Thank you for this video. I appreciate your balance of the technical talk. It's not so deep, that I fall asleep, its not so simple, that I don't learn.
AMD does AWD! Very nice video with excellent explanations. Super interesting. Thanks.
Truly one of the most intelligent descriptions of how this Magic works....
Many thanks for informative video 👍can we have similar video about latest rav4 hybrid i AWD system?
Thank you Amd. I always wanted to learn how the awd system works. Thought of converting an older Corolla to awd but cost prohibitive and with rear disc like the Matrix or Vibe.
It would be nice if you did a video like this but for the V8 model 4runners that are AWD also, love the video's keep up the awsome content.
The AWD 4Runners just have a center differential that is lockable. By having a center differential, you don't need to worry about front and rear axle speed difference anymore. The only drawback is it's always sending power front to back which causes drivetrain drag and reduce fuel economy. It is however a better system because it is a full time AWD system meaning it always send torque to all wheels regardless speed. Most car AWD systems are "part time" meaning it will disengage above certain speeds to have less drive train drag to better fuel economy.
Very good explanation for a neophyte as I am. Interesting system.
Love these tech videos
Great contribution to the society for a better, safter living.
I intentionally bought a non-AWD 2015 RAV4 because I didn't want that rear diff running when it wasn't needed....Learned something today. Thanks.
You’ll save on tires too because on AWD systems all the tires have to match.
Just went and replaced my coupler this week. Wish this video came out sooner.
Excellent
These are the BEST videos, IMHO (how components work). I never knew that towing an AWD vehicle with wheels on the ground will damage the drive train. This is also true with Toyota Hybrids without AWD. On Hybrids, you can generate electricity if towing with the front tires on the ground and potentially start a fire.
I don't understand wheels on the ground.
How is the trailer going to move if it has no wheels on it.
@@Mr-pn2eh what he means is if you are getting your car towed. Not to have the wheels on the ground of you ruin your car's awd system
@@Mr-pn2eh Put it on a flatbed truck or put a dolly under all wheels.
Great video! I have 2IS AWD, 3IS AWD, GS350 AWD, Sienna AWD, & Tundra 4WD. The Lexus is setup is different but you've cover that in other videos.
I am looking for that video (how 2IS and 3IS awd system works), can you please share it?
thank you!
Interesting video. We previously had a 10' RX350 AWD. Previous owner replaced thr transfer case, for what reason we'll never know. When we got it the passenger output seal leaked. New seals and a new axle never solved it. Which led me to assume maybe the t-case was replaced due to this issue and the problem returned, and they dumped it and then i was the lucky new owner of the problem. We never did figure it out and at this point doesnt matter I guess, but still perplexed me and many techs. Ended up dumping it ourselves to Caravana, and then followed the vin. It ended up at auction and shipped to Ukraine of all places.
Great video for young technicians like us
Thanks!
I recently bought my son a Rav4 XLE Hybrid for earning his doctorate in mechanical engineering, and it's such a nice vehicle I'm now thinking about getting one for my wife. It's tough to beat 41 mpg, all-wheel-drive, Toyota Safety Sense, great engineering and reliability all in one package. I'm waiting on a next gen 4Runner for myself.
What Toyota & Lexus models are equipped with a 'torque-vectoring AWD system'? By the way, what a kind man you are, making such an informative lecture available for us! Thank you.
Google can tell you easily.
I'd love it if you can do another video about the beefier systems in the trucks, like the Torsen and diff locks in like a 2008 4runner. I think Torsens are one of the most beautiful things ever created
Yet another brillant video, AMD! Keeping abreast with preventative maintenance such as changing the Gear Oil in differentials on a regular basis (I recall from a previous video that you recommended it be done every 30k miles) would be a key factor for long-term reliability, besides the other issues to avoid that you mentioned in this video. How often should the Gear Oil be changed in the transfer cases?
I always learn something with your great videos. Thank you! May be add trick about removing rear diff stick air breather (press fit. Rav4 2015)
