Title: Rear End Leaking.
Post by: Unofficial on August 14, 2008, 10:38:32 pm

I've noticed for a long time now that I've been leaking something. When I put headers on my truck, I pulled the oil dipstick out of the block, and ever since then, it hasn't been in right. I thought all the spots where I park at were from oil leaking out, but I noticed that my rear end cover was wet at the bottom. I smelled the stuff on the ground and it was gear lube. I've noticed a clicking noise in the rear axle area when I'm driving slow. Could this have anything to do with my problem? Has anyone else had a problem like this?

Does fluid cover the bottom side of the housing in a trail that begins at the pinion seal or is it just wet at the bottom of the cover.  If it's the latter, it's a quick easy fix.  Take out the fill/sight plug and see where your fluid level is at.

I think I saw some wetness on the end of the driveshaft before the differential, is that what you mean? What's involved when fixing a broken pinion seal?
