My 2005 RX330 has taken to shaking badly when I hit 70 mph and above on highways; also shakes when I first start braking at those speeds. Shaking comes right through the steerinf wheel as well.
I'm not sure if the problem is warped rotors (front? back?), tires out of alignment, or if there a specific RX-type problem anyone is aware of, like bushing slipping.
Tires have 50,000 miles on them, so they need to be replaced anyway. I'm thinking of replacing them with same Michellins as came on care (real pleased with tires so far).
So, I was thinking of getting tires replaced, seeing if that fixes problem. If not, going to presume rotors need to be rebalanced/replaced.
Any thoughts or recommendations?
