My rear diff is leaking from the front where the driveshaft goes in. There is diff fluid sprayed on the mufflers and the body above the diff. I have had the rear seal replaced at least twice in two years. Is there something that could be causing the rear seal to fail? Perhaps a problem with the yoke, pinion angle, or the actual housing itself? Any help would be appreciated...

sounds liek something might be misaligned, bent or out of balance. I'd start with the driveshaft.

Not likely. All seals will eventually fail, this is no different. Just replace the seal and clean the area.

This problem resulted in me having to rebuild the rear end about a year ago. Is it reasonable that the seal would fail again that quickly? How difficult is it to change the rear seal? Does the fluid need to be changed as well? If I use Mobil 1 75W 140 do I need the friction modifier? Thanks for the help.

There is a good chance that it can fail again. Now how quickly, that depends on if the seal itself was bad or the install damaged it.
