- This is a guide on how to replace the diff fluid on a Ford F150 between the years of 1996-2004. The video was done on a 8.8 rear end no limited slip. So if you have a different sized rear end or a limited slip you might need different fluid and/or the limited slip additive. Thanks for watching!

First time I've ever seen anyone use construction silicone as an auto gasket sealant, LOL.
RTV is RTV as long as it has a good heat range it will work the same. Thanks for watching!
You haven't lived haha
Great suggestion for storing the silicon. Just last night I was fighting with mine to get it to flow...then I covered mine with plastic wrap and a rubberband. But I like this way of silicone storage better. Thanks.
Thanks dude. Very informative. Appreciate your time
My pleasure!

brake cleaner works too when cleaning the gears on the rear diff and cover.
Thanks for the video I'll be doing My 97 f150 4.6 2wd it looks pretty simple but it's gonna be a hastle taking off because there's always an issue when it hasn't been taking care of and still has the original!
2000 f150 4.6 V8 .The rear end held 3 quarts of 75 W 140.
John Davis thank you
Thumbs Up!!!!
Hate all the commercials, and all respect due it sounded like I was getting a tram tour at an amusement park. But you got the job done thanks.
I gotta eat too. Sorry about that. Thanks for watching!
Muchas gracias amigo ...bendiciones
You are welcome! Thanks for watching!
@@2carpros gracias por compartir tus conocimientos 😉
Thanks dude
Thank You.
Welcome!
that was a great video they want $250 at the dealership to do that job
These videos keep giving my wife ideas for me to do on the weekends. lol
You Can also use Alcohol to Clean Gasket Cover and Around the Metal area all around Works great
Question: I have a 1996 F150 XL I have replaced the drum brakes. When driving I hear a squeaking noise from the rear driver side. Will replacing the diff fluid work with reducing that squeak? Thanks for this great video by the way.
Make sure your drum brakes are adjusted correctly. I'm not sure replacing the diff fluid would help that but it is good maintenance! Thanks for watching!
What’s the purpose of the paper gasket when the silicone is put on both sides?
I was like, "Holup⁉🤔"
Hi, can I put the gasket Wit no rtv? Thanks...
Yes I want to do this this weekend but I don't have a ratchet gun can I do it with a hand ratchett and tighten bolts if I can't get him to spec ?.
Hand ratchet will work great. I just used an impact gun for convenience. Thanks for watching!
Please can you help in anyway I have a rattle after acceleration, not no heat shield nor loose bolts or gaskets on exhaust system not the crank shaft pully or the belt tensioner it's not brackets on exhaust system it's a metalicy sound and gets quiet around 2nd 3rd gear it also makes the sound in neutral only when revving oils perfect in rear diff and engine and in intermediate idc but meby too much or too little in idc ? Would that cause it ? Thanks in advance paul p.s freelander 1 ESX k series engine 1.8
Put the e brake on put it in neutral go under it and try to find the source of the noise.
Why would you use silicone the gasket is made to seal it?
That was my thought they make a gasket for a reason TO SEAL IT UP. Why spend 13-15$ on a gasket to just to silicon it in that case just use silicon LOL.
@@mentallyderanged9169 because gaskets can be put to immediate use.
@@mentallyderanged9169 have you ever done a water pump? Same thing, there's a gasket but you need a silicone seal right?? The answer is Yes
I have done MANY water pumps and thermostats NEVER use anything besides the gaskets it came with. You can use silicon if you want too and or to hold the gasket in place BUT it is NOT a must use silicon on gaskets. To each their own but if you HAD to use silicon the water pump for instance instructions would said MUST use silicon on gasket which it doesn’t. It does say MAY use a very light coat to hold gasket in place for instal.
Silicone works as a sealant. Helps keep everything in and ensures that any possible areas of scoring, digging, etc are filled so it doesn't leak
I don't think it matters, but was this a truck with an automatic transmission, or with a 5 speed manual cause mines is 5 speed maunal, 4*4 with a 4.6 engine and I'm jus only haven trouble with the tiny security screw that holds the pin in place, it keeps loosing, Red thread locker doesn't seem to work, I may need to flood it with lock tight, I really don't want to, I got the truck new in 02, and yes it has high mileage, approximately, 950,000 miles, still runs great except for the rear end issues I'm experiencing. Any advise.
Well first of congratulations on nearly a million miles on your truck there! Honestly if I were you I'd go to a wrecking yard and get a new used diff with the same ratio as the old one. Thanks for watching!
Hi great video. I have a question. Can I use a pump to suck out the old fluid and add the new fluid? I know it won't get all the old fluid out but I have so much rust on the bolts I would not want to strip/ break anything off.
No
I wouldn’t see why not. Not all of us like to pay a small fortune to pay a garage to do it, and we don’t have a car/truck lift.
could I use the Felpro RDS55341 gasket on a 1995 f-150 with a 5.0 EFI engine My diff as 10 bolts and looks exactly as yous....Thank...good viveo you made....Carl
Yeah probably, I believe it is the same differential. Thanks for watching!
Ok I replaced the rear end seal in my ford step by step but the dif is still leaking should I try and replacethe same seal again with more silicone? Or try the front seal near the drive shaft?
If it's leaking out the differential seal then yes try the silicon thing. Thanks for watching!
I have a 2000 f150, I was told I don’t need a gasket, just silicone. I got red gasket maker(don’t know how that came about, lol) question is, do I not need a gasket? And if not, will the red gasket maker work? Thanks in advance
I have seen people just use RTV. I like to use both. Thanks for watching!
Should I use the silicone rubber on the transmission pan as well?
Yep. Nice thin film. Thanks for watching!
Well it sure worked when I silconed around the bolt holes
Yeah only way to make sure it doesn't leak. Thanks for watching Lane!
Do you have to change the gasket every time you change the fluid?
Absolutely. Thanks for watching!
Extra points for knowing "Second verse, same as the first"
I played guitar all through highschool and college. Thanks for watching!
would the procedure be the same for 2000 Lincoln Navigator? Same fluid?
Really similar if not the same. Just double check on the fluid amount in relation to the ring gear size. Thanks for watching!
Where the brake lines split to the left of diff, cover?
Will it hurt if I put Valvoline full synthetic 75 140 and it contains limited slip additive in my rear end
Did you get an answer
Do you need silicone if using a gasket??
no but it’s a good safety measure if the gasket fails
Can you use break cleaner to clean all the differential better..??
It's nearly the same stuff. Thanks for watching!
I have a 2002 triton 4.6 v8 do i use aditive or no? Why the silicon and not just the gasket
Depends on if you have a limited slip or not. Your VIN will tell you. This is why both ruclips.net/video/cx9rfHvGe8U/видео.html Thanks for watching!
You said you need the separate friction mod but the oil I bought (royal purple) for mine has friction mod in it so does that mean I’m set
Yep. Thanks for watching!
@@2carpros thanks for the reply
Something he failed to mention if you're using synthetic differential fluid leave one inch of space between the hole where your adding fluid and call it good because the synthetic fluid expands! And if it has nowhere to expand to guess what it's going to do it's going to blow your seal!
I'm gearing up to do this little project myself and this is what four different mechanics have told me these exact same words leave one inch of space between the level of oil in the differential and the feel plug if you're using synthetic, and they also said that synthetic does last longer however they did recommend changing it out ever so often depending on your own maintenance schedule.
I personally just bought this 1999 Ford f150 and I'm currently going through all this stuff myself just for Peace of mind and before winter gets here so it's not going to be balls ass cold outside and I have a bad issue , I even plan on having a radiator flush done real soon the belts and hoses look real good so I'm not too worried about them.
I call bullshit. Why doesn't it expand in an engine?
@@madmikesmallenginerepair2804 Actually, he is partially correct, but for the wrong reason. My manual says fill to 6-14mm (1/4 - 9/16") below fill plug for this axle. Not sure why, as the the 10.25" axle gets filled right up to the drain plug, and uses synthetic oil as well.
There's a vent tube for your differential. I found this our when I went too deep into the water to launch a boat. Drip tube wasn't strapped down properly and took in some water and now I'm changing the fluid in my differential
Do you have to do anything to the front on a 2003 f150 2wd?
A 2wd F150 wouldn't have a front differential. Thanks for watching!
is this the same procedure that I can use in a 2004 ford expedition?
Yes it is! Thanks for watching!
There are gaskets you can buy.
Should I get a gasket or create one?
Gasket and RTV like I did in the video. Thanks for watching!
@@2carpros
Thanks for sharing!
I'm confused, you used silicone and not RTV which is what you normally reccomended. Should I not use RTV?
RTV is silicone. It just needs to be rated for oil resistance. Thanks for watching!
you dont need RTV, torque on cover is 25-35, and 15-30 on fill plug
Here's what happens if you don't. ruclips.net/video/cx9rfHvGe8U/видео.html Thanks for watching!
Is this the same process for a 2wd 97 F-150?
Yep. Thanks for watching!
I was at my local Ford dealer today. And they told me I don't need to use a gasket. And didn't have one to sell me. So I am gonna buy an aftermarket one.
I wouldn't buy one from the dealer anyways! They probably just use a ton of RTV and call it good. Thanks for watching!
lavcopricetech i knew i recognized u hahaha
Haha that feels like a lifetime ago. Thanks so much for watching!
Hey good video but why using silicone when you have a gasket 🧐
Ooooo I made a great video on that ruclips.net/video/cx9rfHvGe8U/видео.html Basically, so it doesn't leak. Thanks for watching!
does anyone know where i can order the bolts for the diff cover? i snapped one . . .
Check Summit Racing or Rockauto they usually have odds and ends like that. Thanks for watching!
Can you put the fluid in where the breather hose is?
.
My car has traveled 195,000 kilometers, is it possible to change the differential oil or not?
Yes you should do it at that mileage. Thanks for watching!
Torque wrench is free, but not the size socket you need!
I didn’t even know they make a gasket for diffs. I’ve never seen one. 😂
For American diffs they do. Thanks for watching!
Like the video. All that work to clean the steel cover, but no clean up for the bolt heads? lol
How many Fluid will I need?
2.3 Quarts I believe. Thanks for watching!
Gasket gun? Thats just a angle die grinder?
Yeah that's the technical name for it. I just call it a gasket gun due to me using it to take gaskets off. Thanks for watching!
Call me crazy but uh....what's the point of using silicone or gasket maker if you have an actual gasket?
They don't always work like you think they would and it's cheap insurance. Thanks for watching!
Do you realize you only need to pat both sides of gasket with RTV without beads and piles of excess oozing out. Just wet the gasket…
Either way. Thanks for watching!
