     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.

#2: There is no such thing as impossible, it just takes longer.

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.

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.

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.
