2" x 3" drive shaft alignment.

[lftnwhls]

I recently lowered my 1999 extendacab 2" and 3". I used the beltech kit. I can adjust the drive shaft vertical adjustment but not the horizontal should I notch out the holes in the hangar bearing bracket? :fire: I have a decent vibration :whacko: when excellerating.

You might try shimming your pinion angle first. That will probably take care of most, if not all, of a mild vibration.
