Last August I had the pinion seal replaced in my rear diff. I pulled the 3rd member myself and took it into Rearend Specialties. That seal was maybe a year and a half old. Now, 7 months later, I'm leaking again. I don't have time to pull the 3rd member so I'm dropping the rig off to them tomorrow to check it out.

Any thoughts as to how/why a seal is blowing again? What should I/they look for when digging in there. I wouldn't expect the seal to trash this often!
