Hi,
I have an 03 RX300 and I noticed lately that when I hit just below 40mph the front end starts having pretty heavy vibrations, almost like a shaking. I can feel it through the steering wheel and the pedal. The worst is between 40mph to 45 mph. It tapers off at around 50mph. It's still there but lighter at higher speeds. It only seems to be present on acceleration. For some reason, and maybe it's me but it seems to be coming from the front passenger side. If I let go of the accelerator and stay at that speed or I am going down a hill at that speed, no vibration. The rotors and pads are only a few months old and they are OEM. The tires have a lot of tread left and are in good condition. Just before winter I had the tires installed and balanced and they were fine before this. I had it in a snow bank and there was ice stuck to the wheels. I thought it was that so I used a blow dryer to melt it off. It still had the same issue afterwards. If anyone has any ideas that would be greatly appreciated.
Thanks,
Mark
