I lowered my truck 00 GMC Ex-cab 2/4 (LCA & shackle/hanger) and I also put a Powertrax locking differnetal in at the same time. When I am driving at a steady speed and I let off of the gas it pulls slightly to the left and when I put my foot on the gas it goes back to the right. (Or vise versa, I cant remember) I dont know if the Powertraxx or the lowering that is doing this or neither but it is somewhat annoying.
I dont notice it until I change speeds. All of the bolts seem tight. Any ideas?

Sounds like something is out of whack in the rear end. Re-check the lowering job not just for tight/loose bolts, but double check the install and make sure that everything is where it should be.

Also, check the lug nuts and make sure that they're tight. I had a loose wheel on one of my vehicles and it acted JUST like that.

 

call a priest! that thing is possessed!

 

Its typical of a locker. I wouldn't worry about it too much, just get used to it.

 

A Powertrax will cause that? Because why? I guess I don't understand the physics of it.

pressing the gas on and off locks and unlocks the locker, causes wired things while driving. I have a detroit in my k5 and yeah its typical, just have to get used to it, eventually ur brain will turn the wheel slighty for u when u press and let off the gas.......at least mine did

 

Exactly
