Hello everyone any on this problem would be helpful 91 Camaro 700r4
The problem is it makes like a humming or wow wows noise in drive not coasting
Ive put new alminum driveshaft
Transmission rebuilt
new rearend done by driveline shop its not coming from ring pinion
I have put 2 inch lowering springs in it could it be pinion angle
it cant be tires it only does when u push gas
any suggestions would be very helpful

 

Sounds kinda like a pinion bearing/problem u never know the bearing could be bad /shrug

 

Pinoin bearing would they replace that on rearend rebuild where that bearing at

 

Sopunds like a bearing in the rear end or the rear end is not set up correctly. I would say that it is for sure in the rear end. Lots of people say that they know how to do rear end but most can just get by and get it close. I would have a reputable shop take a look at the rear end.
