I have been getting a vibration from the front end. It usually starts when hitting a bump and stops the same way or a decrease in speed. Its in the front right hand side. I've taken it down to the hub and see nothing loose. Anyone have a suggestion?

 

I also am having the same vibration and on the same side, i have checked the U-bolts on the leaf springs and found one of them loose, called the local ford dealer and got the torque specs and tightened them and it did not help the problem. i have looked at the leaf spring and found the two leafs are off set from one another, but are not wearing on any thing. as of right now i don't have a clue as to what is causing this vibration.

 

I do not know if I have the same problem but mine is also on the right side.A roar isnoticeable when the truck is heavily loaded or when making a left turn which places weight on the right front. I have replaced the entire front axle components as I was told this was the fix. It was not. I only hear the roar when RPM's are above 2000 and the pitch of the roar seems to change with engine RPM's.
