i cannot figure out what the clunking sound coming from my driver side front side is when i go over bumps or potholes dont se nothing loose or wrong.does anyboby else have this problem?

What year is your truck? (post in your Sig). How many Miles?
Could be a bad shock. OEM shocks suck.
Could maybe be a wheel bearing that many seem to replace at 60-80K miles. Driverside seem to fail more than passenger side. To check loose bearing, jack wheel off ground, grab top and bottem with hands, and rock back and forth to look for play.
Maybe a sway bar loose or something?
Just a couple guess'

I'm gonna go with the wheelbearing. dave

Kind of sound like the intermediate streering shaft. Is it more noticable when you turn to the left? If you think that's it there is a quick and simple fix in Do It Yourself.

steering shaft...my 04hd did it my 06 did it, and everybody I know who has a chevy does it, the dealer can fix easy of do it you self

It could be a ball joint???? I had one go on my passenger side and it made a clunking sound. Just a thought.
