Rear Stearing Problem?

[Esc]

Hi guys.

i did search but couldn't find anything on this.

i have a 33 gtst s2 and when i drive and go over bumps. ie. train tracks.

i can feel the back end move around a bit.

i was wondering. would it be something wrong with the 4 wheel steer?

i thought maybe its loose or something so when i hit a bump the back wheels move causeing me to feel the movement?

thanks.

What is the centre of wheel to guard height? Sounds like bump steer, and is usually caused by excessive lowering.

340mm is the best height for handling and comfort. Lower than that you are sacrificing handling and comfort for looks

may also want to get your shock absorbers checked out....does the rear skip around at all when you hit a bump whilst accelerating or under brakes?

thank you both for your input.

I don't think the car has been lowered much. i know it has sports suspension. the car has 17inch rims with tyres 255/40/17 on the rear and 245/45/17 on the front.

the rear left shock absorber makes a noise when you hit a large bump. (go over a speed hump to fast)

and it moves around whenever i hit a bump, whether accelerating or braking.

i think more so by accelerating.

if i accelerate around a corner and hit a bump. it moves around alot it feels really light asif the back is bouncing around (which i know it isn't lifting off the ground lol) but yeh.

its really annoying because it doesn't even have to be a big bump. jsut driving on a crappy road with a few pot-holes makes it move.

i know i need new tyre's rear ones are completly bald. which i am going to get new ones when it goes for compliance.

also i'm going to get a wheel alignment on all 4 wheels. and i'll get the rear left shock absorber checked out. and see what happends from there.

any more suggestions would be great.

thanks

Ive got the same problem with my car, im thinking its the wheel alignment as i have just replaced all 4 shocks with bilsteins.

Ive had this problem from the moment i got the car so hopefully someone can get the answer.

Ill be getting a wheel alignment in a couple of weeks so ill let you know if it fixes the problem.

Rear wheel alignment is most likely out.

Mine did the exact same thing, took it in, got it aligned, it HAD been running 7mm toe in!

Hey guys, i know this is an old thread but just thought id let everyone know that i had the same problem with my car and it ended up being my wheel alignment.

The rear of the car was running 12mm toe out on one side and 7 or 8mm toe in on the other side.

The car handles much much better now.

Thanks, Mike.

Had the same problem. It was simply a shock absorber (driver's side).

Replaced it and the problem was gone. Should check wheel alignment also. I get mine done every six months or so.
