The rear differential on my 94 is leaking and I'm pretty sure its leakingfrom the pinion seal. I was wondering if this was an easy fix or if its a job best done at a shop?

 

What is your mechanical background/ability? It really isn't all that difficult to replace, but does require the removal of the front yoke.

 

After reading/talking to a couple of people I don't think itsabove my ability level. I read the chilton manual and they list a couple of special tools; pinion holder/remover and seal installer. Are these necessary, or can it be done with out them?
