Have you 'wobbled' the car from side to side at either front or rear fender? What you will be checking would be bearings, or anything loose that might swing into something. Next, try pushing down at each wheel from the fenders (all 4) so as to deflect each wheel to a low point for any noise/thumps. Do you have a lift available? If so check each point where the rubber Guibo's and the u-joint is located. The rubber breaks down and of course the u-joint mught be worn out. Good luck!
