okay i just did a 3 inch lift on my 84 4x4 pick up. i feel vibrations coming from upfront does anyone have an idea of what it can be? i know that the stabilizer bar almost makes contact with another bar that connects to the axel, but wouldnt that only make contact upon turning. the jerky/jumpyness i feel is at take off the quicker the more it does it sometimes it doesnt, and i dont mean a burn out launch i mean a normal take off. when i go slower i hold the clutch in a lil longer and giving it gas so its not so rough on the take off. what might cause that, so if anyone knows please let me know thanks

 

bump

 

Aw man that could be anything. Take the lift out and see if it goes away. If it does the truck might be too high.

Very possibly SOMETHING is too high...

First place I would check is for binding. Both hubs are unlocked? Wheels spin freely on jack stands, exhibiting behavior typical for open diff?
