Are shims enough (1 Viewer)

[rayho91]

ok so i have a 4 inch hell creek lift and about another 1inch lift on a shackels
so a total about 5 in and no doubt it vibrates like a mother &%$#
so i installed some shims and was wonderin if that would do the job
or am i goin to have to do somethin to the other side of the drve shaft

Can you describe the vibration?

Does it happen in 4wd or 2?

What are you pinion angles?

Did you shim front? Rear? Did you measure caster?

What year 40 are we talking about?

Any chance tires could be out of balance?

it vibrates in 2wd at about 25mph and up
and for sure its becasue of the lift cause i had it for ten years and just lifted it
i put the shims in the rear cause when i eye ball it the rear looks like it needs it
i corrected the pinion angles back to original using the shims
so i was just wonderin if its enough
i havent put it all back together yet

Did you take your shaft apart?
