Does it get worse when turning right? Is it constant, or does it increase with your road speed? Is it a clickety kind of thump? Sounds like your CV joints are knackered. If you can see if the rubber boots that go around the CV joint is torn or greasy, or even gone, that would give you a big clue. Check in the local paper for someplace specializing in CV joint replacements, I have seen as cheap as $99 a side. If that is indeed what it is, do yourself a favor and replace both half-axles. Good luck, hope that helps.

The engines timing could be advanced to much. If it's a front wheel drive a CV joint could be going bad. Knowing a more precise area of where the sound is coming from might help to identify the problem.

Gears inside the motor break and the door starts to move and drops back down when hitting the broken gear = thump thump thump.See "Related Questions" below for lots of help with changing this part - not too hard nor terribly expensive.
A noise from the front end while accelerating could indicate several potential issues, such as worn-out CV joints, a failing wheel bearing, or problems with the suspension components. If the noise changes with speed or during turns, it may help identify the source. It's advisable to have the vehicle inspected by a professional mechanic to diagnose and address the issue before it leads to further damage. Ignoring such noises can compromise safety and performance.
