Clunk on Aceleration from a stop

[8500lbs]

If the clunk is on acceleration and braking then it sounds like hubs might be bad or as you have already fixed bearings. If the clunk is is when turing the wheels left or right and so forth then I would look into the steering components more. I have had both of these problems and I am curently in the process of re-doing the entire steering system. This including new pitman arm, new Idler arm idler support, pitman support and idler block, with new tierods to finish it off.The clunk sound on acceleration was fixed for me when I replaced the HUB.

thanks
