i have an 01 gs300 with about 50k miles , i ve noticed that when iam on the highyway at about 60 mph , my steering wheels starts to shake real bad , it keeps going until i pass the 80mph mark . i was wondering if anyone has the same prob. ? i dont have rims just the stocks and no lowering springs either...

 

welcome to the club, Stan.

 

damn it , u too???

 

Yea I got some hub centric rings, it helped a little, although I do have aftermarket 18's.

 

Alot of us have this problem, including me.. Getting the daizen bushings installed next week, hopefully some relief.

 

hmmm , has anyone on here ever had the bushings changed .?? let me know luciano if it helped.....

 

Yep that should pretty much solve it, also get your wheels balanced, that should help for now and check the tire preasure to be the same in all wheels, Stan.

 

My steering has alot of play and feels unstable at high speeds.. I went to get a province inspection to renew my plates and the car didn't pass. Mechanic told me the lower control arm bushings are shot. I have over 100K Miles though.

Some things to consider:

Wheel balance with the Hunter 9700 machine for precise wheel balancing.
Daizen bushings or replace lower/upper control arms.
Adjust steering pre-tensioner (worked for some I believe)
Ball joints if you havn't done them.
Check tire pressure like mentioned already.

I'll let you know how it goes with my Daizen bushings install.

 

i really wonder if it's wheel balance problem

 

I had the same problem with my car when I first bought it. It would shake right at 60mph, but if I accelerate to 70mph or so, it goes away.

I had to get my front wheels balanced. That solved the problem. Do that before you spend a lot of money on bushings.
