Hello,
I have removed my rear differential to update seals, wheel bearings, bushings... but I never opened the differential which itself seems to be in solid condition. It was leaking from the front, and I intend to replace the pinion seal.
My question is, does the pinion seal housing ever leak? Is removal and reinstallation straight forward or do I need to worry about anything that is not obvious? Since the axle is out, I want to take care of anything that could be a problem now, but I also don't want to fix something that isn't broken and create an unintentional problem. From my experience differential covers don't leak that often but I also have read of a recommendation to remove the front housing cover.

Thanks!
