I just bought a used gs300. I get a "thump" feeling coming from my right front tire.. it is EVER so light.. you really have to be feeling for it to realize its happening. It coincides with the rotation of the tire and to me seems to happen every time the tire turns.. it is very hard to detect and unnoticeable on bumpy roads.. The tire looks almost new the rim seems fine... what could it be???

 

make sure your wheel is on there tight.

 

check your wheels first if wheels are ok and tight on there. check the shock and the top if it's roose from there it might make thump noice everytime you move or hit some bump or something. if nothing is wrong there you might want to check out your bushings and other stuff if it's tight. it's good idea to move forward and back while someone else look at the wheel. if the wheel moves back or forward while the car is moving that might make thump noice when car i moving...

 

Yea check suspension especially the strut rod bushing! they always seem to be bad

 

or just a flat spot on the tire from sitting too long or skidding to a stop.

 

make sure the tire is balanced.

 

check if the tires are balanced. a bad control arm could make a thump noise as well. or a blown shock.
