Ok, here's the deal. I finishe my swap a little over 3 weeks ago. First two weeks, everythings running fine, no codes, grinds, etc. I let my friend drive it, and a day after, I hear a thudding sound when the car is rolling. At first I think wheels are loose, but their good. I check the axles and cv joint, those are straight. I can't figure out what that thudding sound is. Maybe wheel baring? When I accellerate, the car shakes, but when I', cruising it's ok. Any thoughts? Thanks in advance.

 

bad axle? are they from autozone or something similar? might want to check it again. you might have a bad reman. axle.
