     Start with what Irish said, if not then move to suspension lift.  I know it sounds out of place, but if you do not align the suspension when you install it and get both axles straight, it will make it travel down the road sideways.  But like always, start with the easiest things first.

You replaced your brake lines, right? Go bleed them again.

Your axles can be off a little. Measure tube to tube (f to r) at each side (l and r), and diagonally.

i'll give it a shot...i may haul it.....but what can they do to a straight axle vehicle? ???

A proper alignment will reveal if there are any issues by taking into consideration SAI, Set Back, caster, camber, toe, toe out on turns, Thrust angle etc. Knowing those measurements you can easily determine what the problem is. Say the steering arm or knuckle is bent. Do you think you will have correct toe out on turns? Of course not so an alignment is key.

i agree that a proper alignment check will find problems. but what i dnt understand is how they adjust anything on a solid straight axle ???

If you find everything is in spec you set the toe and the steer ahead. Unless you install eccentric ball joints that's about all you can adjust.

Post by: Irish_Alley on January 20, 2011, 05:08:25 pm

You have tie rods to adjust. One thing you can do is take the tires off put a couple lugs back on to hold the rotor back on and measure the front of the rotor on the left side to the right side then do the same for the rear see what's different

Also maybe the axle nuts on one side or the other could be to tight of lose
