I have a 89 pickup and I just lowerded it a couple days ago and for some reason everytime I give it gas and let off it seems to pull to one side. Anyone knows why that might be.
Measure each side of your axle to a reference point on your frame. If you did not put the centering pins back into the leaves, one side of your axle might be forward or back from center, making it want to drive out from under the truck.
