ive read several threads about people hearing a clunking noise when going over bumps and im having the same problem coming from the front. but i was wondering how you know for sure if its ur lca's or uca's that are causing it? is it just by looking at the bushings? mine looked fine. the only thing i noticed was that my upper ball joints had some grease coming out of them. not alot but you could see it. any suggestions or help would be appreciated

 

Its hard to tell unless you take it apart. The bushings will seem fine (unless they are really shot) when its on the car... but all the ones I had worked with, as soon as you unbolt it, the bushings fall apart.

You can unbolt the upper without messing with the alignment and see if the ball joint is weird.
