My rear is leaking oil. So im gonna put in a new gasket. Im a poor man right now, cant afford to rebuild it. What oil do i use? And how do i put oil in it?
 
Since you are really poor, just use RTV and skip the gasket completely.

You use 85w-90 gear oil with 4 oz. of friction modifier. Both can be had at autozone or it's equivalent.

The only way to drain it is to remove the cover. Just leave the top bolt in, remove the rest and pry the bottom. It will start coming out. Then clean the surface really well on the cover and diff, add some rtv and reinstall the cover. There is a plug on the front of the diff, which takes a 3/8 or 1/2 square to loose (i.e. socket extension).

After 30 minutes or so, when the rtv is dry, add the 4oz of friction modifier first, then add gear oil until it comes out the hole. Then put the plug in and you are done.

Check for leaks after you drive it and get the diff warm.

no dude, i wouldnt use the gasket if someone gave it to me for free. use rtv, its the best way to go.

As far as the low on oil thing goes, I cant forsee you being low. its not an engine, it doesnt burn it. your 1-tire fire is a diff problem.
 
Where is it leaking? If at the pinion seal, messing with the cover isnt gonna help it.

As mentioned, if you have one wheel peel, the trac lok has perhaps seen better days and a rebuild could be in order (the kit is about 50 bucks).

3/8" square ratchet fitting for the fill plug. Wear your mechanics gloves when you break that fill plug loose - there have been a couple guys on here who ripped their hands open decently when the plug broke loose.

Good luck.

but it does leak.

:bang: whoops. sorry about that

Im in agreeance (sp?) with Hissin. Make sure its coming from the cover and not the pinion seal. Im sure the leak is obvious... probably a nice ugly mud spot where it is. although, when i owned my 95, my pinion seal was leaking, but it was such a minimal amount i didnt notice until i was changing the fuel pump.
 
Use RTV like mentioned above. I clean the differential cover real good and make sure the differential housing is real clean, then using black RTV put a bead on the diff cover and spread it flat with your finger, I let it tack up for about 15 minutes and install it. I've never had one leak by using this method.

ok thanks for the tip on the gloves. And yes it does seem to leak from the cover. The pionion is were it connects to the DS right? If so no oils coming from there. I seen there like 40 bucks ro rebuild but i wouldn't be able to install. Im sure a shop would rape me like always, unless i go to Nogales, Sonora again like i did my gears lol
 
You got it. A pinion seal leak normally slings oil on the rear of your mufflers and into the axle/tailpipe tunnel.

Have fun swappin fluid. If you dont plan on being in there again for a little bit, synthetic might not be a bad idea. Figured under 20 bucks for a couple bottles. If you leave the friction modifier out of whatever fluid you use, it might help with the one wheel peel. If the rear chatters too much and bothers you, you can always add the modifier later (it's only like 4 ounces).

Going to Nogales for gears - :nice:
 
lol hell yeah it cost me 70 bucks for the install and whinning either!!!! It was a pita!!!!!!!!!!! Putting the fluid that is!!!!!! Oh god!!!! I put cheap oil. since hopefully i rebuild it soon.
