Car swaying at highway speeds

Car swaying at highway speeds
Car hydroplaned into a guard rail and now after repairs it randomly sways at high speeds on the freeway. The accident cause damage to the rear quarter panel and front passenger panel. Things replaced were (right) rear hub assembly and rim. Front end, the right ball joint, drive axle, control arm, and tie rod end. My friend also replaced the rack and pinion. Alignment and new set of tires were put on and just as I thought that would fix everything at high freeway speeds around 55+ the car feels like it's swaying like winds are pushing it? Any ideas as to what else needs to be checked?

Hi, My `04 is doing the same thing. I have a rear sway bar and a front tower brace sway bar as well as the front sway bar bushing upgrade. Just recently replaced stock struts on front and still have "wind pushing effect" I have researched and found its also called "Bump Steer" and is affected by road surface more than anything else. I just found the air pressure at 45lbs on front drivers tire and 32lbs on passenger side. Corrected and hope it fixes, will find out on drive home tonight. The alignment is my next step, after that I guess I will have to check tire rotation and maybe wheel balance. Also my steering wheel has minor vibrations at 60-70MPH that comes and goes with change in speed.. Bump Steer is caused by "caster" adjustment according to most research on internet.
Will post up results of tire pressure adjustment, over inflation could cause excessive/hyper feedback from road surfaces???
