Sounds like a tire may have a flat spot on it, causeing it to make a thump noise. the main cause for this is bad shocks or struts on that side.

SOURCE: thumping noise in the front end

Rotate tires front to back and test drive if same thumping is felt then tires not the problem.
Next check out ball joints/ tie rods
Dont believe it is the rotors unless thumping happens only when applying brakes
Good luck

SOURCE: Right front is making a loud thumping noise

Better check CV joints. No vibration on higher speeds?

2002 olds intrigue shakes while idling with brake on in drive


The cause is too low an idle and engine is starving for fuel so it shakes like that.The thumping sound you hear is most likely just the exhaust being too close to the floor amd bumping against it when in drive with brake on.You said yourself that it stops when you put it in nuetral,well the engine speed goes up when there's no stress on it.With some one holding the brake and it's sitting there thumping,set the idle speed up just enough to make the engine stop rocking that way.

When i put it into gear Drive or Reverse it makes a thump sound. It is fine when driving. Any thoughts


Obviously something is going on in your transmission. If your not having any issues with it other then that thump sound, then I'm not sure there's a problem with it. If the "thump" is very loud or enough to shake the car substantially, then you may want to get it checked out my your local mechanic.

2010 camry click sound at the front, as the car start firt acceleration in drive gear. thanks


yes, i just bought a 2010 camry in Decmber 09, it hasn't been a month yet, and I hear that light "thump" sound coming from the hood, when the car is put into drive after turning it on. As i drive off, and the spee reaches 15 mph, i hear that thump sound. The dealership said that that is due to the ABS system being initialized. How many other people hear that. For some people it might not be a thump type of sound it might be a loud "click" type of sound. Please let us know. Thanks.

A BEARING MAKES A GROWELING NOISE.
