??'s about p.s.

[BUXMAN66]

just recently i've replaced the ball joints (both upper's and lower's... both sides) idler arm,tie rods (inner's,outers,and adj.sleeves) wheel bearings (rollers)..both inners and outers,and replaced the p.s. pump (pump and hoses were bad) and it still seems as though the steering seems to want to wander some. p.s. is working great...at least i can now paralell park at cruise-ins.the problem seems to be that at high way speeds or even at residencial type speeds the steering wants to wander a bit....steering is tight...it responds to the least bit of motion to the steering wheel.it seems to not want to correct itself after making a left or a right hand turn...shouldn't the power steering bring it back to center?the only thing i can think of would be the gear box,but it seems to be working fine,hell i can drive w/ 1 finger on the wheel if need be.what seems to be the problem?.....the only frt. end parts not replaced were the upper and lower "A" arms pivot bushings.the lowering of the frt. (3") has seemed to magnify this problem somewhat.....the lowering has gotten rid of alot of the body sway associated w/ the steering "wandering" problem.anyone got any idea's??? sorry for the long post.....
