I just had my rearend rebuilt in November '03. Parts include Eaton posi, moser 31 splines, and all new bearings. The only used part includes my FRPP 4.10 and the axle bearings.
After maybe 600 miles and about 7 trips down the strip, I noticed a high pitched noise from the rear end. I replaced my U-Joint and the noise is still there. If the car is cold, it takes about a mile for the noise to start and is only heard between 5-40 mph.
Does this sound like the pinion bearing and why would a new bearing go bad. Poor Install??? I ordered all the parts and had them installed locally. The installer said it would cost me another 2-4 hrs of labor ($110-$220) to replace the pinion bearing if it is the problem.
Any suggestions? Does this sound fair?
