91 explorer axle under

[sryan]

I have 1991 explorer, did axle under added or took nothing else. Question, do i have to adjust pinion angle?

no, you shouldn't have to. some have to get their driveshaft extended, some don't...but that's pretty much it.

Thanx, I lifted my explorer about 2 years ago, thats when problem started.After axle swap I adjusted pinion angle, why, because a freind told me thats what I should do!Ever sense then I have had vibration at 65mph plus. I march, put 33's on. with 456 gears.That little vibration became bad.. so I went back to the begining to realize I should not have
screwed with the pinion angle.... thank you for backing up my suspitions!
