I know exactly what you are refering to w/ it being squeemish, all over the road as if it was swaying back and forth..Along w/ going over dips and bumps in the road, it wants @times to change lanes.. I can tell you, no one seems to know what is wrong w/ my car..I've had it at the dealer and they said couldn't find anything wrong w/ it..My mechanic, who used to work for the dealer and opened his owned his own shop, said same thing..I took mine for an alignment and found a bad tie rod end that both places missed(how can that be overlooked?) and new front struts, upper control arms bushings, strut rod bushings,ball joints,rear carrier bushings, tranny mount bushings, motor mounts, new front tires and then the alignment..It still is doing the SAME thing and people looking at me like I'm crazy...So I let a few people drive it, to see if they notice what I did..Right of the bat my Mother did and before any comments on my Mother, she is 54 and learned to drive in a stock car-race car and is one of the better drivers on the road, and not a slow poke by far..My father felt it too as well as a couple friends..So, my point is the alignment should tell what is wrong but not always, thats truth and don't spend alot of trying to find the problem...I think I spent too much and thats why I wanted to reply to help keep you from going down the same road as I, I also have recently spoke to 2 people who have done exactly as I and are still having the same problem and 1 is an SC400 owner...If you find the problem and solution PLEASE let me know!! I'm about 2 steps from rolling mine off a cliff or i could just trade it in..but I like the dramatics of rolling it off a cliff...lol...Good Luck to you and Hope my info here will help you get to the problem w/OUT spending a lot of money and time.. Peace
