I just had my 2004 TJ re-geared which included new axle seals, bearings, pinion seals & nuts, etc.. Broke the gears in properly and re-filled the diffs. with non synthetic fluid (Chevron Delo ESI 80W-90) since I had a Tru Trac LSD installed in the rear. Just the other day I noticed the rear pinion seal weeping fluid. The shop will make good on this as the work is under warranty. The shop is a well known Jeep shop and I am certain the seal was installed correctly but is this unusual? The front pinion seal is fine. The rear diff. was not over filled as my cover has a dip stick for checking proper level. Anybody else ever run into this?
