I have had the steering wheel wobble on my GS 400 for the last 2 yrs and no one can get rid of it. I have 109,000 miles on the car and the wobble has been a severe annoyance from 50,000 miles. All the dealer told me was that my after market Milia wheels were the cause so I recently bought new original equipment wheels(17 inch) and new tires and it is still there. My tire shop guy who has been in the business for 20+ yrs. has turned the brake rotors and checked the suspension for looseness many many times and he says it is tight. The dealer did install some new suspension bushings at about 90,000 miles that helped a little. It almost feels like the steering wheel is loose. It happens of course right between 60-75 mph. If anyone has any ideas I would greatly appreciate it. I absolutely love the car and want to keep it a few more years but this makes driving it almost intolerable.
