Just changed diff fluid on my dads 2014 3.5, this is for sure a better way to do it, the fluid was pretty pricey, but that's what's called in, Thanks next time,
Solid videos man! I think I’ve watched all your F-150 videos. Can you do a coolant flush? No one has a video for a coolant flush on Gen 2 eco boost engines!
If that was the first time the fluid was changed you should have removed the cover to clean all of the break-in fluid out... hope you don't get metal swimming around in there.
@@stevenc9207 not dumb at all. There is a sump area at the very bottom of the housing that holds quite a bit of oil. This is where most of the debris from gear wear or lsd clutch wear will settle out. Pulling the cover allows for a better removal of this oil containing the debris, which gives a better resultant fluid change out. That debris cannot be removed from the vacuum method shown, this will cause accelerated bearing wear if left in place.
How bad is it to use 80w90 in the rear diff? My 16 f150 called for 80w90 in the front and 75w80 in the rear, but the mechanic put 80w90 in both. Wondering if it's a big deal and if I should take it back.
I'm sure the oil weight will be fine. Hopefully he put in a good synthetic that will hold up for a long time. The rear diff gets more heat and load abuse than the front diff. Conventional oil will be fine too, I'd just do a follow up service a little sooner than if it was synthetic (like 30k instead of maybe 60k)
@@MasterJacks sorry. Meant to say 75w85 for the rear (not 75w80). It's not that much of a difference. I think it was a synthetic blend. I sort of treat synthetic like it's normal oil. Yeah the oil might not brake down as quick, but it's all the stuff floating around in it that will mess things up haha
@@kenj.8897 theirs also a little bottle of anti friction additive your suppose to ad but most full synthetic wont need but if you frel it chattering add the additive its like 10$ from ford.

What gear oil would you recommend for a 2018 f150 with the electronic differential? I was thinking Amsoil or royal purple or even valvoline but all of them contain some friction modifier additive would it be ok?
Ford calls for Motorcraft 75W-85 Synthetic in all their 2018 rear diffs. Using an alternate brand with a similar protection range (with or without a friction modifier) is acceptable.The friction modifier helps keep limited-slip friction plates from sticking. It it doesn't have limited slip, it will have not effect. The electronic locking rear diff is not affected by having or not having a friction modifier.
I always wonder on mileage... my old Tundra is was 100k... I really dont know on Fords. It says 100k somewhere in my documents but I do not trust that...
Industry standard is around 30-60k, but it really depends on the extremes it's exposed to. Heavy towing or a lot of around town start/stop would have me lean towards or more frequent interval. For most users, 100k is probably fine, just nice to stay ahead of the game before grime starts taking out seals.
I'm not sure if the raptor has limited slip or not. Adding a friction modifier will not harm a standard differential, but it is necessary if it is limited slip. Short answer, if you put some in you're safe either way. If you bought the fluid from your dealer, they could decode your vin and let you know what you have.
@@sacem52 found this on the web "All differentials use gears, bearings and shims. Limited-slip differentials have additional clutch packs. Since there is nothing in any differential that is not in a limited-slip differential, there should be no harm in using a friction modifier in a non-limited-slip differential, although there is no need for it."

So I have an extractor... is it a good idea to do this or do I need to remove the cover to clear the magnet?? I dont pull anything.... I'm at 39000 miles with a rear wheel drive 3.5 standard engine
Pulling the rear cover allows you to check out the rear gears and to clean any settled grime that may have accumulated. At 39k, I don't think you'd see much wear.
@@MasterJacks My Dodge Durango has a magnet epoxied in the sump to hold the debris. Pretty good idea, however I didn’t know it was there the first time I serviced the truck, and got a needle sharp piece of gear debris skewered into my fingertip while wiping out the oil left after cover removal.

The TopSider is a great extractor. It will outlast any of the plastic models for sure.
One hint , don't put pressure on top of can , it will collapse. Ask me how I know .No foot on top
Thank you!

Thanks! I've got a coolant flush in the plans, hopefully I'll get to it sooner than later. I'm a man of many projects :-)

That's a valid consideration. I'm not sure if it was the first service, but likely it was.
How do you do that?

No additive? Mine had the grinds multiple times, needed substantial amount of friction modifier added.
Good video, I made an incorrect comment an Thamac15 called me out on it, good looking out mate.
Friction modifier is only for limited slip differentials. This one in the video is electronic locking. You’re lame!
@@Thamac15 lol yeah I was wrong, I saw a few vids back then an didn't know only the LS Diffs needed it. I will change my comment. Cheers
How many quarts for a 2017 f150 with traction control? Thanks
Hi
Do you have link where I buy canister pump like your
Thank you so much
I have the Amazon link to the pump I use on my website. Thanks for watching! www.masterjacks.com/2016-f150-trans-service
Like the suction method, but how can you be sure you got all of it out?
Check the service manual to see how much it holds then pump it out and measure. As long as it you get the majority out you should be good.
@@Timothy2890 Ended up doing this myself by taking off the cover and re-sealing it. 2.5 Quarts removed, 2.5 added 👍.
Do you have to use Ford fluid?
74-140 gear oil lucas works like butter..
Butter 🧈 isn’t a good gear lube tho.
The idea of pulling the cover is to inspect it. That's why there is no drain
and yet so many other vehicles have a drain
So what? Still doesn't mean a drain plug wouldn't be helpful or nice. Removing the cover to drain is dumb

No there’s no drain plug? It must be extracted?
Typically on a read diff, you pull the rear cover to drain it. Extractor is another option.

would it be okay to use 75w90 instead of the 75w85.

Is LS additive necessary on a '20 Raptor?

Short answer, if you put some in you're safe either way. If you bought the fluid from your dealer, they could decode your vin and let you know what you have.
If the Raptor has a L6 (elocker code is on the driver door label) then no modifier is needed....only a limited slip diff requires modifier
What 75w-90 would you use for the front & rear diff?
I would feel fine with any full synthetic in that weight.
MasterJacks does it matter if it’s a limited slip hypoid fluid like Valvoline Synpower 75w90?

Do you know how many thousand mile do I need to change I use oil gear Ford
Thx so much
Probably around every 60k miles. More if towing often or a lot of city driving.

Thx so much for help me

How many miles should you do this?
Depends how much towing you're doing. Industry average is about every 30k.

I did my first one at 60k. All regular driving no towing. If you’re towing id do it ever 30k.
There are better more professional videos on UA-cam that shows you the correct way to do this job.
This is not the right way to change the fluid. You didn’t clean off the magnet.
I just changed my 2016 F165 @ 89,000 miles. There was still some brown in the oil.
Wow. What an aweful way to do it.
Need to check and clean any metal shavings.

Pulling the rear cover allows you to check out the rear gears and to clean any settled grime that may have accumulated. At 39k, I don't think you'd see much wear.
Also, the magnet is built into the fill plug. They don't put one in the bottom as it can dislodge and take out bearings.
