My 2wd f150 just started clanking recently when I drive over bumbs. It doesn't do it when I sit still and turn the wheels. Also I've jacked it up and checked the ball joints with a pry bar and had 2 other decent mechanics look at it and ride in it. They said they really don't kno what it is. Could still be ball joints could be spring boots or shocks. Any ideas?

if it happens also when you're braking. I'd start looking at bushings. Radius arm bushings, axle pivot bushings. You really need to try and reproduce the sound when it's sitting still, if that makes sense.

Yea I understand I believe ichanged the radias arm budging last year and i remember it would thunk really loud when you would turn the wheel. This one is difrent it's like a rattle/clank if u get what I'm saying when I hit bumps it like rattles.

Where is the pivot bushing?

Flareside Thunder has it radial arm bushings they make a thumping sound when they are worn out. When this bushing goes it is usually time for a complete bush replacement job front end wise thankfully with the modern Poly "U" bushes you will not have to do it again.

It's the end of the TTB that doesn't have a wheel/tire on it.

See the parts list below from LMC Trucks. Look at the radius bushing and the axle pivot bushing. Have fun.

It's not making a thumping noise that the radias arms did it only does it when I go over bumps or tracks it will like rattle like maybe the shock idk it's difrent not very loud just enough it aggravates me.
How could Make it reproduce the noise if it's te axle pivot?
