My 8-3/4" was rebuilt a year ago with all new bearings, seals, and a new clutch style sure-grip unit. It gives me a pretty heavy popping sound that you can feel when coming out of a slow speed tight corner. It never does it on a straightaway. At first I assumed it was the tight new sure grip unit struggling a little to slip around the corner. It also will turn over the inside tire a little bit on tight turns. But, its been a year or so now (approx. 2500 mi.) and its still making this noise. Could something be wrong in there? or is this normal? It was set up by a pro and I'd take it back to him, but it was a used gear-set and he said he wouldn't warranty it because of that. I may still end up taking it to him to check out, but what do you guys think of this....
