Can anyone help me with the problem with my 98 Lexus GS400. I get a vibration on the steering wheel on and off at different speeds. I have gotten the wheels balanced, aligned, and also have bought new rims and done the balancing and alignment, but the vibration is still there. I have taken it to the dealer but haven't gotten anywhere. They tell me to balance and do the alignment which I have already done. It usually happens at around 60 mph and higher. Any kind of help would be great.
