Default Thump??!!??

Could be a bad control arm bearing - basically it bangs around loosly in the socket (the socket housing gets stretched over time).

Does it sound only when you run over something or take a turn? Sound like its coming from a wheel?

i still have to take off the original lugnuts <img border="0" src=smileys/smiley19.gif border="0">
