Hi there
My '96 Tahoe makes whining noise on the rear differential . When accelarating, it's loud, when the car is rolling without any force from motor or transmission on the diff, it's noiseless, when the car is decelarating (downhill without giving gas), it's also doing noise, but different then the one while accelerating. I suppose it's the differential main-bearing, but i read that it's a common problem of the Tahoe's and that, even if bearings are replaced, the noise can still be there. Of course, i want to avoid changing sth and pay money for it when it's useless. So, does the change of the bearings help out or should i use special oil or is there sth else that can be done so that the noise dissapears ? The Tahoe has about 100.000 mls.
Thanx for the hints....
