tried that I switched to a set of stock wheels but did not do any thing i think i might pull the plate off the diff to check the gears i ment to say that i checked the fluid level. but come to think of it the guy that i bought it from just did axle seals mabey some chunks tore up the seals:jawdrop:

It also could have kicked off a weight of the Driveline. Have your Driveshaft checked for balanced or if your lowered it could be a pinion angle problem
