I have a whobbling/thumping noise somewhere in the front of my car. I especially notice it in parking lots going slow. I asked a mechanic about it and he thought it may be something to do with a tire. I don't believe that is it, because I replaced my two front tires about a month ago. I do sometimes feel a small vibration in the accelerator and my steering teters (not shake) left and right a little when I let go of the steering wheel while in motion like on the highway.

Any thoughts? bad alignment? loose ball joint? bearing going bad?

something loose or worn in the suspension?

The first thing to come to my mind when you list your symptoms is wheelbearings. They'll cause most of those symptoms. I wouldn't rule out tires, though just because they're new doesn't always mean good. You may have a loose cord that wasn't fully seated when the tire was manufactured. I'd try rotating the tires before anything else. Good luck with it.

I had a 77 Cutlass that had a similar problem. I just put new tires on the front end and had it aligned. It shook,wobbled, shimmied, and thumped at all speeds. I couldn't figure out what was wrong. I checked the suspension, bearings, and every thing else I could think of. Finally took it to my mechanic and found out it was a broken cord in the right front. I had the tire replaced and it solved the problem.
