    Help, I just bought my Blazer and the 10 bolt in the rear is making noise. It only does it when Im on the gas, when its coasting it goes away. My friend thinks its the pinion bearing. Any one out there had this same problem before?

    Mine did the same thing on my '91 10 bolt rear. Made a horrible screaching type of sound under acceleration, it was the pinion bearing.

    Right now I dont have a shop and this thing is still under warranty, do you know how long it would take to swap the bearing?

    I had mine replaced by a shop, and it took them about 6 hours or so I beleive to do it, but I also had them put new seals and bearings in the entire rear end. If it's under warranty, call whoever you bought it from and make an appointment to have it fixed.

    It could be alot of different things, but to make sure it is the rear I would pull off the driveshaft and check the u-jt's. If they are ok check the diff fluid in both the diff and the tcase. Make sure they are full. Next I would pull the rear diff cover and look for metal, teeth, etc.
