Well I have just got my car back and had installed 3.73's, vigilante 2800, and pcmforless. I have found somethine weird though. When I am moving at really low speeds like just out of park I can seem to hear the gear and pinion it sounds like gripping one another, is this normal? I have only driven it like a couple miles and after I drove it for the first minute the noises from the rear went away. I am thinking that it is ecause the gears are not lubricated well yet. Is this normal???

 

Give it some time to break in and I Think you'll be ok, as long as it doesn't feel like they're binding up I think you're fine.

 

I let it cool down and took it for a spin again right now. I am pretty sure it is just because they are breaking in because now it hardly did it at all.

 

Just remember to change your differential oil in a little while, to get all the shavings out.
