Steering Wheel Never Stays Centers & Bumpsteer

My 99 GS3 steering wheel never stays centered . I done changed every front suspension part except sway bar , I changed rack bushing , LCA 1 & 2 , UCA , endlinks , ball joint , tires all that and got an alignment , the problem is sometimes the steering is centered and I might turn a corner or just keep driving next thing I notice steering off to the right or off to the left , never stays center but pretty much track straight until about 70mph is where I start noticing bump steer when going over bumps or anything uneven , kinda feel like the tires are bouncy . I am running 18x8 with 225/45 OEM Lexus wheels in the front and fender is sitting right at the top of the tire .. Coulda RCA help me with this ? Or any suggestions ?

Was going to say rack bushings but you changed those. Hmmm, Upper arms? maybe the upper bushings are shot, or the rack itself.

Are you trying to self diagnose or the suspension shop has done examination?

Reason I say that is the lift that the suspension shop has can configure loaded/unloaded situations and those guys can easily stress the joints with levers. At home I could not do much other than look for play min the steering link.

I just recently removed the Lower control arm and now waiting to get the alignment. I plan to go to a speed shop for alignment and not one of the speedy chain. Will cost ne 2x.

Have you checked the tensioner on the steering rack?

I just changed UCA last February with Megan UCA . I was thinking maybe the rack , but it doesn’t leak or anything , I installed steering rack bushing last February also . You think it could cause the play like that though ?
