Anyone fix "the clunk"

When going over bumps I can feel a solid clunk right under my feet like someone is under the truck with a hammer. Been underneath many times lookin for the culprit but nothing is loose. Does anyone have a similar problem or maybe a fix?

Could be ball joints, spring bushings, loose or worn out shock.....

Re-torque the trac bar mounts and bar ends.

There was a body mount right under my feet in the excursion and it made a thunk on bumps and under heavy braking.

The clunking sound that I had in the past, turned out to be the front (driverside) bushing on the swaybar. It had came out of the bracket holder. Popped it back in, and has been fine since.

The only clunk I have had is the track bar. It was easy to find because I could cause the clunk by turning the steering wheel back and forth.

Take your sway bar completely off and see if the clunk is still there. Then you'll be able to narrow it down.
