thumping noise above 30

I have a wierd noise that is only when my car is moving, that usually starts at above 30MPH.

It's like a "thump, thump, thump" noise, not quite at fast as every wheel rotation. I can't hear it with the front end off the ground, only when I'm driving.

For a while I thought it was just road noise, but there is also slight vibration in the floor at the same rate as the thumping.

Since I've had this problem I've replaced the Wheels and tires, both ball joints, both drive axels, both sway bar links, and one control arm.

Help...

Why heck, how about front wheel bearings...normally, you would hear them at slower speed.

Do you have a thermal-gun, to evaluate temperature? I'd drive it, and see what the bearing temp is.

I'd say wheel bearings, make sure that you put the new seals in the steering knuckles or you will have to put another set of wheel bearings on. You will have to get the drive axles out to get to the seals. The seals come with the bearings in the box.
