I Have a thumping sound when applying brakes or throttle quickly. If i ease into brake or gas i usually don't hear it. i replaced gearbox, ball joints, outter tie rod, inner tie rod, hub assembly, alignment. I am getting alignment re-done next week. THe sound is like putting a weight on a rod and shaking it so it slides and hits each end and makes a thump sound. i bought a new intermediate steering shaft. a local garage told me it didn't need replaced, just the gearbox. any ideas what this annoying sound can be from?

 

Welcome to DF
I will move your post in the section that can help you out.

 

If you hear it on both braking, and acceleration, I would start looking at u-joints.

 

+1 on checking U joints.

 

.i replaced u joints on both sides of front end axel. its just one thump/clud sound when applying break or gas. it doesn't always do it either. sounds like something is lose. i was told it could have something to do with slip joint in steering shaft???

 

They are more referring to the u-joints in the rear driveshaft, but inspecting your steering components can't hurt anything.

 

Where abouts are they located? Its my first 4x4.

 

So maybe that has always the problem I've notice a clunk loose feeling from back end when driving up hill and turning left onto road. I would feel a clunk coming from bed of truck....like almost a wiggling feelingut

 

Check mounts and such too. U-joints are easy to see, they are basically the same things you changed in the front axle, just a bit bigger.... should be two, one on each end of the shaft.

 

what mounts do you mean the ones that support the bed?
