Re: I'm getting an odd 'thumping' noise that seems
My guess is the rear axle CV-joint.
Once a CV-joint bearing surface gets pitted they will cause a random knocking or intermitten knocking at the rate of the CV-joint rotation which is the wheel speed. Often more noticeable when starting off or accelerating at lower speeds rather than at a constant cruse speed. My Porsche would knock more when accelerating out of a turn in one direction more than the other.
The rear wheel bearings typically cause a higher frequency constant rumble.
The drive shaft center bearing and CV-joint failure indication is similar to the rear axle except the frequency is 3 times the rate of the wheel rotation.
However, if your having other issued like tramlining or rear wheel shake it could be a loose rear wishbones or guide link ball joints.
