My clank in the rear end turns out to be partially very warn spider gears in my 1997 Chrysler 8.25 rear end. I'm paying $350 to replace the outer seal where the drive shaft connects (it's leaking pretty bad) and the spider gears. Does that sound reasonable?

Please don't suggest I do it, I am unable, does this amount sound like it's in the ball park?

 

$350 for a pinion seal? RUN to a different mechanic.

 

I would call other shops see what they say its gonna cost you.
