When I'm driving, occasionally a loud rhythmic thumping will come from the driver side wheel well, like something is catching with every wheel rotation. When I let off the gas and the vehicle slows a bit it stops, then I can get back up to speed and it wont happen again for a while. any ideas? its not a squeak nor does it start and stop with the application of the brakes. It appears to have to do with the speed, though it has happened between 30-60 mph. I would ignore it, but I'm worried it may become more frequent. there is also a lot more vibration of the vehicle than before. it isn't the engine, I had it checked. thank you for your time.

It could be many things. Have you checked to make sure the wheel is tight? Have you checked the tire to see if the tread is worn evenly? Have you checked for a shifted belt in the tire? Have you checked wheel bearings, CV joints, and all steering components?
