I have a clunk/rattle when driven over manhole cover or road cracks.
Recently replaced tires, shocks, ball joints, pitman arm, steering gear, sway bar bushings, and sway bar end links. Steering is good and ride is nice. But WHen I hit a bump at any speed it clunks. Steering joints are good. The sound comes from the driver side wheel and i can feel the clunk on the floor board/gas pedal. I also replaced the drivers side brake caliper. My control arm bushings are checked but intact. THis clucnk is driving me crazy chasing it. I was hoping to let my son drive the truck to school, but not until i solve/correct this clunk. Any ideas? Thanks!

 

I would take a closer look at the control arm bushings.... jack it up, and shake things around, see what happens.

 

I got the same problem with my 96 4x4 and have replaced everything under the front end except the shocks can't figure it out but I can get on 95 and 80 to 85 and runs like a dream even in town but like u said when u go over bumps I got the same rattle/clunk I gave up trying to find it I'll know when it brakes I have put it on a lift and checked every thing but everything is tight and up to par I just took a 300 mile trip and made it there and made it back game today and it's no worse but it does drive me up the wall and machanic

Check shock mounts. These have to be TIGHT...crazy torque value ....iirc....

 

clunk or thump under driver or passenger feet is loose lower shock bolt.
tighten to about 105 foot pounds.

 

Just torqued the lower shock bolt. IT was tight and not far off from 105 ft lb. Will test drive and see if clunk is gone.

 

Not to scare you, but just a heads up. I had the same problem. It would clunk/bang/rattle/whatever when going over potholes, speedbumps, etc. And then my tire fell of. Sheared all five studs off the rotor. I figured it to be under tightened lugs.

It's unlikely, but it's possible. Sometimes the simplest things...

 

I had pretty much the same symptoms and it turned out to be bad ball joints....
