I just had the whole front control arm bushings replaced, and last week I had the front stabilizer bar links replace from horrible squaking noise when going over bumps/speed bumps.

Ever since the bushings was replaced, if I am driving straight down the road, and say I purposely go over a man hole cover the rear end of the car will shimmy outward the opposite direction from the front wheel that hit the bump, and it's very scary during wet conditions also.

I had the shop look at it twice (once after doing control arm bushings and a second time from another shop when they replaced the links) and they're saying it could be my tires because he said my tires aren't high performance, so I checked and they are and they're brand new, so I'm not sure what the issues is. This all started right after getting the car back from when the bushings was replaced.

Any ideas?

First thought is summer tires not reacting well to new england cold. But that's just a wild a** guess.

Have someone drive behind you and check and see if the front and rear tires follow each other. If whilst driving straight it appears from behind that you are driving at angle. Could be the trust angle if when you floor it with the wheel held straight you walk left or right.

Either way the tire excuse is bull. Troubleshooting 101, it's almost always the last thing done which in your case was suspension work. Do keep us posted though!

Wow!! Thanks Gary, I'll get right on it and let you guys know.

Any update to share? Did you try an alignment?

I sense a shimmy or floating sensation from the rear when going around corners with rough pavement or changing lanes and driving over road reflectors or uneven pavement. Would you say this is the type of sensation you are trying to address too?

Hey all, well I'm not 100% sure, but it was either the tires or the alignment that was way off.

It's very cold here and I still had summer tires on, and the tires were hard as a rock, so when the car was in the shop for an alignment, we received a pounding snow storm, so I wouldn't of made it home with the car (I barely made it there with the summer tires before the storm, it was just dusting on the ground and the car was all over the place) so while it was still at the shop I went to tire rack and picked up some new snow tires and wheels (19's) and now the car is super fine, no shimmy over minor bumps in the road, no jumping lane or slight fishtailing.

So you have proved that 19's really do fit on D4 S8. Cool!

Do you happen to know if you have 380mm or 400mm front brakes?

Oh, and what size rubber is that (width and aspect ratio)?

Kingmoe82

Wheels are 19 x 8.5
Tires are 255 45/19

I have 400mm fronts as well.
