Rear leak

New hear. Been browsing the site for a few days. Lots a good info here it seems.


Anyway I just bought an 04 TJ with 23K miles. I've noticed the last two mornings when I back out of the garage there is a small oil spot on the floor. It looks to be somewhere in the back right corner of where the jeep was parked. Any opinions on what it is. Rear seal? I have to leave it overnight for the spot to appear. Doesn't leak enough to show up in the day while out driving around.

Welcome to WF!

Need more info. Go to the carwash and spray the hell out of the underside. Get under there and eyeball where the leak is coming from. Could be a simple diff gasket or it could be the yoke shaft seal. Either way, it's a simple fix.

Let us know how it goes.

I thought it should be an easy fix. Just figuring out where it's coming from will be fun though. I'll clean the underside up good. The only thing is I have to let it sit all night for the leak to appear. Thanks for the info and the welcome.

Wipe it down real good with a degreaser and watch where the drip comes from. If the drip is near the rear cover, then you know it the diff. cover seal. If the drip flows from under the front portion of the housing (from the yoke shaft seal area), then you know it's the shaft seal.

Very easy to find, just takes a little time. Let it sit overnight.

Is there any oil or heavy dirt build up on the inside of the rear wheels? What about the differential covers?
