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 ?

Have you checked the tensioner on the steering rack?

I recently changed Lower control arm , like 3 weeks ago as the alignment shop told me to do it before getting alignment. Didn’t take it to a suspension shop though did all the work my self n with the help of some buddies .. I got It aligned at a popular shop , wasn’t a chain .
i actually tighten the steering tensioner a lil bit which made it a lil better and former .


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 ?
