Rear diff. leaking

Post by Nubster » Sat Feb 21, 2009 3:13 pm

The rear diff is leaking on my "new" Jeep. Do I just pop the rear cover, drain, clean, seal back up with RTV, and refill with fluid? Just want to make sure so I don't screw it up. And yeah, something this simple I could screw up...lol

And what should I refill with and how much? It is a D35 if that matters.

Cool. Thanks for the fast response. Just standard diff. fluid or is there something else that might be better recommended?

Just your standard gear oil will be good.

I already got and used the red. Everything went pretty smooth especially for me. Now just gotta see if it holds up.

I've always used red also, but any color will work for a differential, blue, black, etc.

-take all the bolts out except the top most bolt, just loosen it.
-give the cover a couple whacks with a rubber mallet to free it, let it drain completely.
-scrape all the old RTV off, i used a razor blade. one of those scrapers they use for inspection stickers would also work well.
-check everything to make sure it looks good.
-you can use some kinda brake parts cleaner on the cover to clean it up.
-then put the new RTV on and match it up, hand tighten the bolts and let it set. i let it set for about an hour, then filled it and tightened the bolts down.

i think that's it, pretty straight forward. i wasn't too sure about it when i did mine, but it was pretty easy.

lol...yeah...that is how I used to do it. I got it all sealed up and looking good. Now fluid is leaking out of the plug hole >:(

Anyone interested in a 1996 DD Jeep Cherokee? I'll make you a great deal.

I used to have gear oil leak out of the crappy rubber plug after I changed my fluid too. After a few days the level will drop slightly and you'll be ok.

I RTV the rubber fill plug before I put it back in. Hasn't leaked out around the plug since.
