Yet another rear end question

[Cobain03]

we installed the "pumpkin" today and we now have another noise comin from the rear. Its liek a wineing noise and its only there when you hit the gas. We also have the previous roaring sound. Any suggestion would be helpful thanks

I am assuming you mean you installed a rebuilt rear end? Was it done by a shop? It sounds like your bearings are making noise, did they install new ones? Maybe they didnt set the backlash correct? Some noise is normal as the new gears first mesh, but what you are describing sounds like it wasnt done correctly.

we done it ourselves and, it was our first one we have done. it could be bearings

gear tolerance

When you installed the gears, do you know what the angle is supposed to be and the tolerance ?
Or did you just wing it ?

Not criticizing, just curious so we have more info.........

Sounds like you need to try it again. Pinion depth, backlash, and bearing preload must be off.
