Hey guys, I have a thumping coming from the pass side (sounds like right under the floor board). Its driving me crazy! I first noticed it after I hit a large pothole that I didnt see in time to avoid . I think its a ball joint poss and it gets louder (or more noticible) as I slow down....

1. How to check if its the ball joint? Lift the wheel and try shaking it up-down, back and forth right?

2. How hard is that to replace?

3. Could it be anything else?

Thanks,
Matthew
