Bad vibration was alxe-wrap

[LukeNukem]

I threw a driveline a while back. I had a gnarly vibe under load ever since even with all new ujoints. After stiffening up my springs by switching out a few leaves, not only does it ride nicer, sit lever and ride 2 inched higher overall, but the vibe is gone...totally. I can accellerate hard 1-3rd and no funk at all. Nice to kill two birds with one stone.

Could it also be because your pinion is now aligned with the driveshaft properly?

I've noticed vibes when my pinion wasn't properly alligned. Usually when it was pointing above the driveshaft angle(would cause more vibe during accelleration).

I agree with OB_Wan.

Sounds like you had vibes because the angle was too great (above) where it should be. Under load, the pinion points up even higher.

Since you're sitting 2" higher now, the driveline is probably a lot better because of the height change.

Yeah, and I was under the impression that Axle-wrap was usually caused by being SOA.

Plus, you have a mad shackle lift, which I've heard can cause problems.

I would also look at your CV. Make sure it is nice and gressy. You can get a needle attachment on a greese gun that works good. Are your u-joints allined?

[LukeNukem]

allined with what?

Your u-joints should be lined up with each other with no more then a 3* angle from rear axle to transfer case.
