I have a 2000 X and evertime I drive over a bump or a pot hole, I hear a "clunck" noise coming from underneigh the front right side near the a-arm. A friend tried rocking the X back and fourth while I checked underneigh. I heard the cluncking noise but I could not see where it was coming from. Does anyone have any idea?

First guess would be a-arm bushings, followed by a bad shock.

skibum1111,

I will replace the shocks first because I have not replaced them yet.

Thank you for the reply and please accept my apologies for my poor manners.

i heard a clunk noise while hunting in 2003 . After coming back from my trip, i brought the xterra to the dealer and they put grease under some connecting parts on the front side. It did the trick.
I don t remember exactly the part. its a stopper of some kind hitting the table when you hit deep holes. Im sure its nothing but get it checked if you want.

I just replaced the front shock absorbers and wala...noise is gone!

Thanks everyone.
