My RX330 has less than 9,000 miles - I have experienced wheel shaking a few times since 5,000 miles - the first time the dealer "fixed" it via replacing brake pads, etc - that time the shaking occured as I stepped on the brake lightly.
But the problem occured again recently. Basically I went rather stable at around 75mph and after 10-15 miles the shaking will gradually start and increase in magnitude, to a point where it was so rapid that I had to pull over. Totally not related to the braking this time. I waited for 30 seconds or so and started again, and the shaking went away.
WIll this be as simple as tire balance? Or something more serious w/ the transmission, etc.? Thanks in advance.
