I would recommend not prying the cover off from the bottom, some covers are REALLY stuck and you might even warp it unknowingly. Pry it off at the top - at least that way IF you do leave a small leak area its ABOVE the fluid line and not below. Just preventative.. very close to that porsche bonnet - id be careful!
Make sure you check you can take the plug out, you dont want to be stuck with an empty rear end and no way to fill it up.
Good advice on a Friday night.
Did you end up disabling that failure parking brake system? I am thinking of doing the same on my 02 Silverado
U made it look easy!!! Awesome..
Torq specs for rear diff 99-07 Tahoe/Suburban/Silverado are 30 ft pounds.
Use 75w90 without LS additive if you have a G80 diff. Which most are. Or use 80w90.
can 80w90 be used in place of Synthetic 75W90. My owners manual calls for 75W90 for the rear and 80W90 for the front diff. 2004 Tahoe Z71

Great Video
I have a 99 gmc yukon denali will this video work for it ? Also it makes a whining noise mechanic said it was differential but not where its located but sound real loud from under my driver seat is this something anyone can do themselves? Please help im carless
Great video! Question? I'm replacing the rear differential fluid on an 07 Chevy Tahoe LT. I'm using the AC DELCO 10-4016 or GM 88900401 full synthetic 75W-90 gear lube. Is there any additional additives required? I did not see any on this video being added. Thanks...
If it's a limited slip differentia will then yes go to your local dealer or AC delco part store or look on Amazon and get the limited slip additive. If it's a straight differential than no attitude is needed and yes run the 75-90 synthetic gear oil. I run Lucas you can use Valvoline you can use mobil one it doesn't make a difference I just suggest using the synthetic in the rear but caution you are to use 8090 in the front differential non synthetic
@@j.cooper2246 synthetic gear oil already has the limited slip modifiers
Great video! :)
Thank you, good video.
Thank you for watching!
Can I use a positive differential on my chevy tahoe 2001?
very weell and thank you very much for you time and help
+Jose Carvajal you are welcome
Nice work..thumbs up
Thank you for watching!
wat type of oil did u use
Do u need a tork wrench ?
Do you need to let the RTV sealant dry before putting the cover on so that it will not contaminate or react with the newly added oil?
+gig777 no you let it get a skin on it. the directions are on the rtv I lrt it sit for several hours after but probably dont need to
Very easy awesome, ty, great video!
Glad it was helpful!
I really like your video. Please turn down the loud irritating back ground music so your conversation can be understood.
On the plastic tag, up and to the left of the fill hole, it states to only fill until fluid is 15-40mm below the fill hole. It appeared to me you filled it until it reached the bottom of the fill hole. Would that not be overfilling it???
Yep.... people be posting horrible how to vids wit incorrect info all the time. Sickening
The owner's manual says the fluid level should be 5/8" to 1 5/8" below the fill hole. The rear differential in this video even has a blue tag saying similar information. Why did you fill it until the oil is coming out of the fill hole?
I know my front differential on my 2004 States what you just said but the rear differential as always been filled to just wear your pinky it's fluid in the fill hole. My Haynes manual does validate that
@@j.cooper2246 for my 2004 silverado it says front fill up to like 0 to 5mm below so pretty much till it runs out..... then rear is 5/8 to 1 5/8 below the fill plug
@@j.cooper2246 right
I just bought at 1995 chevy suburban k1500 4x4 and it did not come with a manual so I can't tell what kind of gear oil it will take in the rear and front
Uses Synthetic 75w - 90w. Mobil One or any comparable brand. Originally had 80w - 90w from the factory but has been updated and GM issued a service bulletin regarding.
Is the differential sealant only applied on one side of the seal?
It's not needed at all. Bad not recommend if using a gasket.
My 2009 Suburban 4x4 only functions properly in "2up" and "auto." Could changing the differential fluid fix the problem? When I change to "4up" or "4down," starts dragging clunking and dragging when I try to drive.
That is a complicated question, if you go to our website www.2carpros.com and ask a question for free, an expert will be along shortly to help! Thanks for watching!
Very nice
is that a drain plug on the bottom of the diff? shown when you are filling it
Yeah but if you're going to be opening it up and cleaning it out, might as well not open one more thing that you don't have to.
Thanks dude
Thanks for watching!
Does anybody know what that bar infront or the differential plate is called?
Sway Bar or stabilizer
what are the intervals for changing the differential fluid for a 2003 silverado ls 2wd?
Ideally every 50k miles
If you value your truck.gear oil is way cheaper than a differential rebuild..i change mine every 30,000. And i dont do a lot of towing .
Very cool
I have an 07 Silverado Z71 1500, and I was looking for the fill plug on the rear diff housing/transfer case, and didn't see it anywhere, but the differential cover has a plug on it, towards the center and to the right that looks like a socket extension can fit into it; is this my fill plug, or the diff cover magnet?
Thanks.
+Skot Ward Yes it is. Mine has the same plug.
After how many miles does the fluid has to be changed? I have a 2010 Silverado but I lost the manual.
Around 100k is the general rule. Thank you for watching!
Every 50,000.. Unless you're doing a lot of towing I would do it every 35 to 40,000. And if you're going to do a lot of towing upgrade your differential cover so it has a fill and drain plug will be very time saving in much easier for fluid changes. My G to cover cost me 150 there are other covers in the market for around a 100 that contain a drain and fill plug. These covers are aluminum and a help to dissipate heat quicker.
You're awesome man, thanks for saving me money.
Thank you so much for watching!
2CarPros can I use gasket sealant? I couldn't find differential sealant.
Do you know if the Eaton G80 requires Friction Modifier Fluid?
I found the answer: SAE 80W-90 Gear Oil that is API "GL-5" compliant.

i HAd the Same 3/8 Snap on Impact
Was Very Expensive and Not Very Powerful
Ingersol Rand Titanium Much Better
now have a m12 KMilwaukee
I like my 3/8's Snappy but there are other good stuff out there. Thanks for watching!
Whats the torque spec..good-n-tight...lol... Rule of thumb is always make sure the fill plug can be removed before you start the differential fluid change. Also IGM rear and typical torques back 25 to 30' pounds and the fill plug is a national pipe tap doesn't need to be more than 10-12' pounds. Also if its A GM vehicle with a limited slip differential make sure you add limited slip additive available at dealership and on line. Or local AC Delco part store.
You are using Motorcraft 75w-140 in a GM rear end? My '95 1500 calls for 80W-90. I usually only see Fords taking 75W-140.
It could be possible that he/ they buy gear oil in bulk (pail) just happened to have that empty bottle.
Scott Haddick Thank you for posting this because that is exactly what happen. Plus we like the top of the motorcraft bottle. Some mechanic's are stuck in there ways of doing the repairs and unfortunately the camera catches it making it hard to explain to the public.
did your differentials insides look like this one cause my 95 silverado looks nothing like this
Your must be a limited slip unit, which looks different, go here to see th-cam.com/video/zarxKsspr3s/w-d-xo.html
2CarPros it looks more like the first one on this video but still different, so i guess i just have a plain open diff, really sucks, anyway thanks
What kind of tool do you use for the plug?
for most cars and trucks just use your 3/8 extension with your ratchet thats all !!
you need to rename this to "Fluid Change".
I do not have any fill hole in the axle housing !
sealant only on one side of the gasket?
It is a gasket the silicone is not needed, we only use it to be a little bit of an overkill.
gotcha. thanks!
So is it important to take the cover off or can you just siphon it off and refill? Obviously taking off the cover is better, but wondering if that big a deal? How often should you replace? (Every 50k? 100k?) Thanks for the video.
If you use Mobil 1 synthetic 75W140 gear oil , you gotta have nothing to worry about it in the next 100K.
Andy Caraway If you do not remove the rear diff cover you wont be able to clean off the old seal and replace it, you also wont be able to clean off the magnet which generally has some metal shavings on it, and if there is a lot of shavings you wont be able to see that as well
Taking off the rear diff cover gives you a chance to clean all that out, replace the seal, and inspect all your gears to make sure there are no worn or missing teeth
Why can't I find the hole to refill it? I've looked and felt a million times but nothing is there. What did I miss?
Just go slow and grab a flash light then look all around the pinion side of the differential. There has to be one.
There is a drain plug at the bottom is there not? I mean, I get the time saving measure of just unbolting the back cover, but there IS a drain plug
icek9a It would also be nice if torque specs were mentioned on the drain/fill plugs as well as the rear bolts on the diff cover
+icek9a Did you see all the built up crap on the inside of the diff cover? You can remove all the metal particles and gunk by taking the entire cover off.
So what's the torque spec for this?
Evidently variatably snug is the torque spec.
@@ablejohnson thanks
You didn't use any brake clean to clean out the gear box and the cover. I would have wanted to get all of that old fluid out of there
The brake cleaner doesn't do any damage right ?
@@clopez6444 No
how much liter oil in differential
I'd buy 3 containers worth. I believe it is 2.4 quarts. But you just fill till it starts coming out. Thanks for watching!
No proper torque procedure "2CarPros"?
20 to 30 pounds would split the gasket and make it leak, just snug is what you want, re-tighten as needed in a few days
@@2carpros Pounds is not a unit of torque.
Why is the plywood in the upper left corner!
It is a piece of 2 by 3 to hold the rear down from the frame as far as possible giving you more room and clearance to work.
Motorcaft fluid on a Chevy? that's a sin! Hahaha
David Stewart jajajja good eye jajjaj he's using ford gear oil, for chevy vehicles jajjaa
I'm glad I'm not the only one that noticed
Was wondering when someone else would catch that also... only came to the comments to see if anyone else did!!
Why not just drain the gear oil out of the drain hole at the bottom of the differential? I saw the drain plug at 4:40.
flapjackthemermaid hard to get all the sludge out by only dropping the oil.
+ricerust they is not a drain plug,, it is a fill plug only and is where the fluid level should be at when the differential is full.
ricerust It is so you can get the bulk of the oil out before taking the cover off. The drain plug is for oil but you must take the cover out and wipe the sludge off with a rag.
There is a magnet inside the pumpkin cover that catches metal flakes that might harm the gears in there. It's the circle you see when he wipes the inside of the cover. You want to get it free of any debris. Also, the gasket has a shelf-life. These are the main reasons for doing it. There are several others...a little gasket compound and a couple paper towels are considerably cheaper than a diff. replacement, doyoyink??
Josh_Outdoors the drain plug is for when Jiffy Lube does your diff. service, the fill plug is for actual mechanics.
what were the torque specs for the bolts
+Polo Ramos we really don't have specs you just want to have them snug but don't over tighten and them recheck them in a few days to make sure they are not loose.
+paulseyes thank you sir
34 lbs for the rear differential. Allow them to sit snug for a bit before torqueing so as not to force any sealant if you use into and contaminate the gear fluid. Same if you just use the gasket bare as I would recommend, to much torqueing initially will split it. Tighten comfortably at first and retighten after a few days.
I seriously think my 2007 chevy suburban has an aftermarket or junkyard rear differential. The drain plug seems to be on that back plate and not on the side like all the videos I’ve seen.
Different years are like that mines on the back plate as well chevy tahoe
great video. The music is kind of annoying.
I have a 2009 Silverado 1500. I went to the dealer to buy a rear gasket, the parts guy said you do not need a gasket, the cover is a reusable non gasket. Needless to say, I haven't changed the fluid yet for fear of not knowing if its going to seal
Get a Gasket. He must have misunderstood the question.
Maybe you upset the guy, what was on your shirt?!
It's called a gasket
thanks for the comment please subscribe
Hahahaha..hahaha
Motorcraft fluid in a gm lol
We used the container of the motorcraft fluid for the nozzle to attach the hose easier we used the appropriate GM gear oil. Good find though Bobby Taylor
Ah, ok lol
Pop me sunba eldiferencia" soi carlos
I use vaseline to keep the gasket on the cover. The gasket will come off easier the next time.
Vaseline will eventually degrade the gasket. Do not use.
I do it this way: ...clean the inner surface and flange of the diff cover and the flange surface of the diff housing...secure the paper gasket onto the clean diff cover by inserting two diff cover bolts opposite of each other into the diff cover bolt holes...marry the diff cover to the diff housing with the two diff cover bolts...insert the remaining eight diff cover bolts...tighten and torque the bolts per spec...vaseline not needed.
so empty the fluidreplace gasketput it backfill fluid up that's it? wtf okay why charge me $250 ill do it my self thanks man
That's it. Thank you for watching!
Always change the cover bolts, Do Not Reuse old originals.
+paulseyes u can reuse them, why would u replace them
Why do people show their ignorance by not using proper punctuation and grammar? Adrian I would suggest taking it to a professional.
So empty the fluid, replace gasket, put it back, fill fluid up and that's it? WTF? Okay why charge me $250? I'll do it my self, thanks man.
@@poorwhiteboy6594 you missed some commas there, fella.
fyi, drain plugs are your friends!
Don't all have one. You need to get in there to clean it out and inspect it properly.

It’s not recommended to use rtv for the rear diff 🤦🏽♂️
Yes it is. I just had a car come in with no RTV, just a gasket and the rear end is leaking like a sieve. Replaced it just like I did in the video and now doesn't leak a drop. Thanks for watching!
2CarPros I’m not saying you can’t use it, I’m stating GM doesn’t recommend using RTV, nor do they use it from the factory. I use a gasket alone, no leaks ever. Most people just think the gasket is just a piece of paper, but it’s the reaction to the gasket from the oil that they forget to think about. Nice video nonetheless 👍
You are very lucky. Everytime I get a car with a leaky rear end it always has just a paper gasket.
I even just got my new diff for my 1967 Camaro custom build by a professional differential shop with 3.73 gears and a detroit truetrac with just a paper gasket. That leaks too at least a couple drops per day. Huge puddle under my car now. So now I get to redo the seal and use RTV, then it won't leak. Thanks for watching!
@@eclecticvisionz2846 probably no leaks because it's no more fluid left!
They don't make any money if you use RTV, they'd rather you not.
All gaskets have an expiration date, it's against the laws of physics for them to never fail, they'll effectually become dust.
RTV expands with the metal and fills micro gaps, hats off to the inventor.
Robert Smith That’s why there’s a thing called service intervals! If people followed them they wouldn’t have to worry about random failures on anything outside of manufacturer defects (OE or Aftermarket) and/or vehicle recalls.
Why do not use , a very good quality differential fluid , like a Mobil 1 synthetic 75w140? and don't worry in your next 100K .
If you use 75w90, make sure it doesn't have the LS additive in it. G80 diffs do not need additive and will be hard on the diff.
Differential fluid smells awful.
Its Grape scented usually ... wouldn't eat a grape that smells like that !
