That's a good next step... If a lot of the suspension components haven't been replaced, I'd lean toward replacing them all (shocks, shock bushings, bumpers, boots etc., tie rod ends, rack boots, sway bar end links, sway bar bushings, rack bushings, etc.) You'll be amazed at how much of a difference it'll make in the handling of the car... I waited until about 150 or 160K to replace everything in the list, and I thought the car handled great - had no idea what I was missing!
Just noticed your location... if you're ever passing through Columbia let me know and I can listen to it for you and give you any suggestions I can think of. -Bring a hash-a-plenty from The Beacon in Spartanburg and I might actually fix it!
