- Welcome to 2CarPros! In this video we are going to cover how to service the rear differential for a Ford F-150 from the years of 2004-2008.
In this video we showcased the 9.75in rear end with a limited slip differential. If you have the 8.8in or 10.25in you need to double check the amount of fluid needed, which gasket you need and, if it has a limited slip differential or not. It could be different.

You are a good man and understand what you do, and I benefited from you, God protect you and take care of you 🫶
Thanks for watching!
I'm doing this on my 1986 F150. Never been done! Great video. Thanks.
I'm a recently hatched DYIer and can do nearly everything. Nearly.

Very cool! Thanks for watching David!
Smart decision.. you will save a lot of money and know things are done right
Always pull your fill plug first!!
How come?
@@rcrbrewster7840 If you can't get it off you are already dead in the water since you can't fill it back up. You will need to wait on taking the oil out until you can get it off. An undrivable vehicle is much worse than just old oil.
You’re right. Always make sure the fill plug comes off first
Thank you guys very helpful definitely getting parts from a good tutorial video case
Glad it was helpful!
Tip.. use a loose stud inserted in top of the diff to align the lid. then thread it out when the other bolts are in
Good on you for trying lol I just can't vlog no matter how much I want easy youtube money....
Short and directly on point is how you will get my vote lol amd any other actual mechanic's
That's so nice of you! Thanks for watching Joey!
Can I do this on my 2005 f150 4x4 with 150xxx mileage I don't know if the previous owners did it before? I watch you videos of the trasmision too can I do It on my trasmision too? And transfer case too?
Yes definitely. They most likely haven't. I have videos on all of those by the way if you want to check those out. Thanks for watching!
I have a 2005 v6 manual trans f150. Subbed.
Thanks for the sub!
Great tutorial bro. Keep up the good work
Thanks for watching!
What does the top left cable does the big one in my car looks like is cut? Can you please tell me what is for?
Great video.
I will be doing this on a 2006 f150
Nice! Thanks for watching!
great video, very helpful, you should also do tutorials on Toyota pickups/4runners.
Thanks for watching!
Good video; however, those bolts need to be torqued down 30 ft-lb, not run the impact all around full force. Most of those 9.75" diffs take 5.5 pints (2.75 qts).
When do you recommend replacing the fluid? I’m getting handed down a truck that has nearly 200k and it has never been changed...
100k is always a good mark according to manual. Personally I enjoy doing the work so I don't go over 60k. You really should change all the fluids if you are getting a truck with a 200k on it. Luckily for you I have plenty of repair videos on this truck for you to check out. Thanks for watching!
@@2carpros already watched the transmission one too 😂 I’m ready and excited to get working on it! Thanks for putting out these videos
@@hunterprice287 did you O ready did it sir if yes how is you truck running I'm thinking to do it on my truck with 150k
@@mambito14 running great. Did the transmission fluid and both differential fluids.
@@hunterprice287 nice I will do my this weekend is you truck running better then before ?
Hi Brian, I own a 2007 F150 5.4L Crew. How do you tell the gear ratio on your rear axle. Also I have 150K on the vehicle when should the rear axle fluid be replaced? Thanks.
So there is 4 ways I can think of right now. You can count the teeth on the ring gear divided by the pinion gear. It is sometimes printed on the ring gear. If your differential tag is still attached it should say it on there. Sometimes if you can find the online Vin decoder it will tell you there. I was lucky enough to still have my new car sticker and it has the 3.73 limited slip differential. You should change it every 100k miles or so. Thanks for watching!
I heard 9.75 rear end came with all 5.4 V8 f150s.
I have a question about it, my truck is 2wd the 8.8in differential need the limited slip additive? Or just with the oil it's enough, or on that case you recommend me a good additive for preserve better the differential
You need to have that information. But you can put limited slip additive in a non limited slip application. Heck a lot of gear oil just comes with it in built it. Thanks for watching!
How do you know the size of your differential so you know how much fluid needed, and how do you know whether you have a limited slip differential? Thank you in advance for your answer!
Can you just use automotive rtv gasket material without the cloth like gasket?
I have seen others do it. I'd do it in a pinch if I had to but I like the gasket. Thanks for watching
I also just used the black stuff hooe works
Wouldn't the gasket itself be okay? or is the rtv required? I am about to do this tomorrow.
Lots of people just use the gasket. I don't because it almost always leaks. The RTV is there to prevent it from leaking. I just got my rear end built for my 1967 Camaro by a professional differential builder. They didn't use RTV and it leaks like a sieve.
I was wondering about that myself. I have changed my differential fluid before and used only the gasket. I was afraid I would goof up the tube of stuff. The gasket has not leaked and it's time to change it again.
I was thinking possibly the reason it leaked on the Camaro is that the housing was not cleaned properly.
Just my 2 cents. Jesus bless.
Good job, all the keyboard warriors will never stop. The end of the day you got the job done. Some people say you have to use gear oil RTV. I use whatever RTV is in stock and/or on sale and I've never had a leak. I went against the the grain and used 75w140 in my 2019 f150 that calls for 75w85 I'm guessing b they changed it for fuel mileage reasons and people beat me down on it. I had a surplus of 75w140 amsoil.
75-140 ...better!
Can I just use the silicon and no gasket at that point
Yeah you can. I like using both but thats me. Thanks for watching!
Should I top it off after warming it up? Or is it supposed to seep out when cold
I took it for a test drive about until the transmission warmed up and then it let me add a few more ounces. Figured it couldn’t hurt?
Transmission or diff? Because this video is for a diff. Thanks for watching!
2CarPros for a diff. I just used the transmission getting warm for an example of how long I test drove it
Is it really necessary to use silicone IF you use the FelPro gasket?
It's cheap insurance if you ask me. Thanks for watching!
Suggest using Gear oil proof Silicone RTV... regular RTV can dissolve when contacted by Gear Oil ... also let the Silicone RTV cure for a few hours too before adding Gear oil , so as to not contaminate the gear oil
It's automotive grade RTV so it's oil proof. Thanks for watching! :)
I have a 2004 f150 fx4. So it’s got the 4wd. Do you know what size my rear diff is either the 8.8 or 9.75? Also I don’t know if I need the 4 oz of the additive or 8 oz
You can type your vin into RockAuto and it should tell you. If I had to guess since yours is an FX4 pretty high trim level it is 9.75 and you need 8 oz. Thanks for watching!
Impact gun is a great way to snap bolt heads during installation. Lol. Make sure to point out the gun is on a low setting. Someone is bound to hammer them to oblivion with a 1/2in 🤣
Im thinking impact best for removing then, while it’s empty, stick to hand tools. Better & safer.
thanks this helps me
Glad to help! Thanks for watching!
I have a F150 2005 when its in the over drive gear and i gas it up it vibrates a little. What you think that causes that?
Sounds like a misfire. You can attach a scanner after you feel that and see if the computer tracks any misfire but not enough to light a check engine light. Thanks for watching!
paul medard misfire, get a code reader. Figure out which cylinder is misfiring. Replace the coil pack. Clean the throttle body with proper cleaner. And put sea foam in your gas and oil. Should run smooth after.
Can you use the old gasket?
Nope. Thanks for watching!
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?
I would get the Motorcraft recommended stuff. Thanks for watching!
Great info!
Great comment! Thanks for watching! :)
@3:15 "I believe mine is 9 inches" Haha you wish!
;) Thanks for watching!
Hey body ..how much pounds need torque for bolts.

I don't get it why, your using silicone,if you installing a new gasket... gasket does the work when you don't have silicone... it's just my opinion.
So it doesn't leak. Check this video out if you are curious th-cam.com/video/cx9rfHvGe8U/w-d-xo.html Thanks for watching!
How many quarters of oil?
I believe it was 2.3 or so. Thanks for watching!
Until it overflows
Ford stealership quoted 1000k. A small shop quoted 420. Then another qouted 150. I think 150 is good price.
1000 bucks?!?!?! Holy moly that's a rip off and a half. 150 seems right. Thanks for watching!
I waa told it takes 4 quarts mine is spilling over at two
I do the same with my wife's differential on her Opel..😆
Use gas to clean the cover it's fast
I can't recommend it due to it being fairly dangerous and people will be mean to me. Thanks for watching!
The shop told my pawpaw it would take all day and cost him 300 bucks
Pretty sure he got ripped off
Well I kind of get the all day thing to let the RTV set. But 300 bucks? Yeah that is waaaaay too much. Thanks for watching!
Whats with the prying implement ..... were not stupid say a flat head screwdriver .... stop being silly
People complain because you aren't technically supposed to use a standard screw driver like that. Thanks for watching!
Pro tip... Before you remove the differential cover and drain the fluid... Make sure you can remove the fill plug.
And if you can't? Just going to never change the fluid? You are going to have to get it out one way or an other. Thanks for watching!
@@2carpros the plug might be rusted in and require days of soaking with penetrating oil, or you may have get a torch and heat the area, or it may have to be drilled out and use an ez out, or it may have to be drilled and retapped. Any one of these operations could take days for you to acquire the necessary equipment or to allow the penetrant to work. I guess if you're okay with having your car sit in your driveway unable to be used because you already drained the fluid while you work on the removal of the fill plug.......
