Re: Pinion Seals
 

I would be wondering about driveline angles then. Did you replace the
bearings with the output? Same for pinion bearings. The last bout of
vibrations would have damaged the bearings to a point and sloppy
bearings will cause a leak again.

The tcase seal was replaced but I don't know about pinion seal. That
said, this is a stock TJ, has not been raised. It's my daily driver,
not a stump jumper. I never could figure out how it got a bent output
shaft the first time. Could there be something causing that problem to
return?

Sure, the bent shaft and the vibrations killed the output bushing or
bearing, same for the pinion bearing. You can keep on putting seals in,
but with a worn bearing, the seals will fast start to leak again.

Leaky seals are only symptoms of deeper troubles, something has to make
them leak.....
