How to service your Ford F150 Front & Rear Differentials | *WARNING* Ford won't tell you this!

[@brad1179]

Don't forget to crack the fill plug BEFORE you take the diff covers off if you're reusing the stock cover. You'll be up shit creek if you drain your oil and can't refill it due to a corroded fill plug.

[@Boobtube.]

yea, what he said.

[@rickreese5794]

Bingo PAL 💯👍😎

[@eddiearchuleta615]

You obviously don’t have a breaker bar and cheater pipe

[@brad1179]

@@eddiearchuleta615 I do have both but I've done shit the hard way for too long in life and learned to take a few extra seconds to save a headache later.

[@victorvillasana3409]

This happened to me on a 20 year old Illinois blazer. Couldn’t break the fill plug loose, ended up stripping the square peg. Had to fill it through the vent tube. Was thinking about making my own hole on the cover.

[@WalkerTexasplumber]

Banks did a great video on the issue with flat back diff covers

[@BackroadDriver]

Agreed. I got a lot of info from their content.

[@mll7674]

I use the same cover but I chose to use the factory gasket. In my experience they are great. Never deal with leaks from them. As long as they don’t get damaged.

[@salsuginusrex5196]

[@J.W.W.]

Stock or Banks for me, but this diff cover looks good too

[@jamestone265]

None do what the Banks do. It’s what you want if you tow a lot.

[@paulcondie2520]

I did front and rear differential at 46,000 miles. Also did my transfer case as well as a transmission flush. Will drop transmission pan and change filter at 60,000 if not before.

[@mcmuskie2563]

Yup, easy to do. I changed all my fluids at break in (40,000) even antifreeze…all Amsoil

[@hansvanhouten1781]

​@@mcmuskie2563what did you guys use for front/back differentials, 75w90? Ford states we have a non limited slip differential unless you have the elocker, so what's the use of the friction modifier everyone adds to their gear oil? I'm assuming having the limited slip additive doesn't hurt a thing tho..

[@ypisoni]

@@hansvanhouten1781 I believe that valvoline 75w90 he used already comes with the friction modifier just in case, BUT and I might be wrong here, I don’t think the e locker style on these need friction modifier, I thought only the raptors have a limited slip on the front differential that needs the friction modifier.

[@Roger-il8iw]

Don’t ever flush it lol. I’d rather do multiple pan drops than flush these.

[@baljeetseggzy7746]

Maybe I’m just an idiot but when I was trying to suck the fluid out the fill port I couldn’t get more then a half a quart.Maybe it’s my pump idk

[@mcmuskie2563]

I brushed Black Tremclad on my rear axel when it was new, still looks new.

[@blackwolf22303]

Thanks! Did these changes a few months ago. My yard still smells like death afterwards due to some spills lol

[@mcmuskie2563]

Ya that fluid stinks like hell

[@drunkenfarmer]

I have a 21 f150 with about 40K miles on it. I just did my transfer case fluid change, which i barely use, and it was super dark. (ford wanted 400 dollars for it, i did it for 30 dollars including the pump) I was planning on doing my rear and front diff's and this video is excellent. I am a big fan of the gasket on my model vs the silicone on the earlier models. no need to wait for the gasket to dry. I will be going back with the stock cover until banks makes one for the f150 tho.

[@666dynomax]

that bronco looks sweet man. love the white.

[@uNkLeRaRa4]

I had my diffs and trans fluids swapped around 120k km's. 150k mile change interval is crazy

[@donnieflame]

My trucks got 280,000km 😂 I've owned it since 220 and idk when it was done last 😂😂😂

[@CandyMan69007]

Glad i seen this video im new to the truck world and never knew anything about this. I have a 23 stx eco boost but only have 7k miles on it.Thank you for making this video

[@sacbluesman]

Geez. Some of the comments you guys have to deal with. This cover looks awesome. I’ve been wanting a curved cover and haven’t been able to find a decent one. The FOrd racing one is nice but that cast iron ain’t doing nothing for cooling. Nice job guys! Hope to see you running around Knoxville one of these days.

[@BackroadDriver]

Thanks man! We don’t worry too much about what people say on the internet.

[@henryford2736]

Just had both diffs checked at 130k. Oil still ok so Ford's 150k is spot on. The transfer case needed new fluid tho. It was really dark. I'm surprised you didn't do your transfer case. My F150 is stock....

[@BackroadDriver]

The diffs might still have fluid in them, but where was it going to go? Was it clean and still within spec? That being said, I'll be doing the transfer case and trans in a video soon. I already have parts on hand. Thanks for watching!

[@fdhicks69]

Oil level may be OK but you have no idea of the viscosity, silicon or particulate contamination levels, water contamination, additive conditions, friction modifier condition (if applicable), evidence of improper top ups (wrong lube), or other elemental contamination whether ferrous or non-ferrous. I first change it out between 20K and 30K when new after break in. Yes, I have easy access to an oil analysis lab.

[@JnitraM078]

Love the Harbor Freight bucket in the background 😉

[@cwqrpportable]

I always enjoy your videos guys! Nice work, appreciate it.......

[@wtfd95]

Did my 19 350 Super Duty diesel at 42K and replaced with BANKS and used Amsoil 75W-140. Very happy! Also replaced front differential with PPE diff and used Amsoil again of 80W90. Really like the collapsible bags to get all the oil out. Great video and service tips. Thanks! 🇺🇸

[@mcmuskie2563]

Did mine at 40,000 as well. Oil is expensive. Around $7.00 per quart. I forget now, but you can Google amount needed. I also brushed Trem Clad onto the rear axle housing, still looks good at 110,000

[@TheLumberJacked]

Man, how is 7$ expensive when you only need to touch it every few years? 🤷🏻‍♂️

[@Liquormans]

Thanks for the Video . I'm picking up my first 4x4 2020 f150 xlt sport on Friday. I've been checking out maintenance videos. Saw this love the cover mod... I'll definitely change the fluids before 150miles or 241000 kilometres. Thanks from Toronton Canada

[@birddog79]

Keep them videos coming guys

[@sixshooter4570]

Factory OEM spec is 33 lb. ft. on the rear differential bolts.

[@ranger178]

reminds me of my boss on my first job bought a heavy-duty pickup for hauling supplies and snowplowing his driveway. so he had garage change rear diff and they forgot to put plug in or tighten it so his truck sprayed all the oil out as he drove on 3 lane highway till rear seized up right in middle of road he tried to move over but truck stopped between two lanes blocking both and it could not be moved or pushed off the road quite a traffic mess that caused till tow truck got him off the road.

[@cristianc6185]

Thanks for your video.I ended up buying one exact differential cover and installed in my 2019 F150 The only thing I want to add is the oil level when you fill it back up it’s not at half glass sighting . I filled it up to half as you suggested and then I opened the original fill plug and put my finger inside the hole and I cannot touch the oil in the differential.I ended up adding a little bit more oil where now it’s 3 quarters full on glass sighting

[@commonduck10]

man, I Haven't seen your channel in 2 years. Great y'all still have your truck. Never new they had something like this in the aftermarket.

[@BackroadDriver]

Stick around a while. Thanks for watching. F150’s get just about everything in the aftermarket.

[@97widerider]

changed mines at 125k for first time in my 2013 5.0. Fluid was dirty but not black. Gears looked good. No scarring or marring of gears and teeth on gears were perfect. Measured almost exactly 3.1 quarts drained and put same back in of Motorcraft gear oil. Did not use permatex green but a Felpro gasket from Advanced Auto and no leaks after several miles of driving. Very easy process so do not be intimidated.

[@itz2klevi412]

Might do this today on my 2017 f 150 but going to keep same cover until later, I got the 3.5eb should I do it?

[@jasonmcdonaldhandmade7900]

i tow a lot hauling shop machinery, trucks and tractors. Have the same rear. I've got 382k miles on it. As well as the 6 speed trans. Great drive train. i also drilled my front diff I the bottom and installed a plug.

[@flyingjeff1984]

Gale Banks will inform you as to why the factory diff cover is the best. He wanted to sell his own so he tested them. It has to do with the fluid getting slung correctly.

[@kelley71]

I bought the Ford Performance one on my truck. It is much easier to service.

[@Rexamillion16]

Banks main point was the flat back covers caused fluid flow issues. The cover he used in this video had a similar round back to direct fluid flow where it's needed.

[@jeffkuipers1030]

when i changed mine on my ranger i used AMSOIL price was more but the protection is most important.

[@brandonmacon3317]

My 21 came with the sealant on the diffs. Will eventually get a banks cover with an actual gasket seeing as how ford has fixed my rear diff twice already and it's leaking a third time.

[@ChristopherSeaDawg]

I replaced my super 8.8 with B&M differential cover. Same awesome features your replacement has. I also used the lube locker gasket. However, I use nothing but Amsoil products, so I went with the severe gear lube.

[@BackroadDriver]

Nice choices. Love Amsoil products. I plan on changing fluid often enough it shouldn't be an issue and keep costs down. Brad has a b&m on his super 8.8.

[@ChristopherSeaDawg]

@@BackroadDriver Also I forgot to add that the B&M holds more fluid, and has carrier support bolts. Helps keep things centered up for launching!

[@ChristopherSeaDawg]

P.S. I love your truck!

[@pmaint1]

My 19 ranger has drain plugs on the opposite side of the axles. Just below the fill plugs.

[@bobmartens1089]

Yup i do it every 60,000km with trans as well

[@mcmuskie2563]

Ya me too, I changed my tranny fluid after I bought a pump for $90,00 and sucked it out. Used Utube to show the process. Tranny fluid had grey particles in it. Change tranny fluid and filter, immediately the shifting was smoother with no hard interruptions some times.

[@coreyyancey9272]

My mom's boyfriend put 80w90 in his 9.75 that called for 75w140...locked that bitch up...starved pinion bearing. He paid me 750 to swap in a junkyard axle so whatever but I would always use exactly what it calls for! Side note it was a 1999 truck and it had a metal tag on one of the diff cover bolts that clearly said 75w140 ONLY.

Wish Dorman would come out with a reasonable Rear diff cover for the 8.8 12 bolt over 300 dollars for a rear diff cover just to get a drain is more then I am willing to pay. Try a biscuit on a angle die grinder on the machine service cleans up like brand new.

I zip tied that line to the hardline above the diff. I might source some longer studs. These lines mount differently on almost every vehicle no matter which rear end you have. I assume that's why most companies don't include new studs, just new regular hardware. I wouldn't recommend trying to reuse the three factory studs.
