Make sure the aft end of the control arms are fully seated in control arm bearing lollypops.

Also did you buy new bearing lollypops and if so did you buy a left and a right?
Those bearings effect your caster and shift the wheel in the opening fwd and aft.

Or possibly you have those bearings flipped.

Last thing. The lollypop bearing bushings you installed are the centered type and not the offset type? The offset type are for adding-removing caster and can cause what you described as well.
