have you cleaned the mating surfaces between the hub/rotor and between the rotor/rim? I recently wire brushed mine, and it made a HUGE difference to my shake, at both 60 to 70, and while lightly braking.
It's a really easy, cheap thing you can try at home... and if it doesnt help, no harm done, no money wasted, only an hour or two.... all I know is I had the shake anywhere from 60-80 mph, even with brand new tires, which made it almost go away, but not quite.... a few thousand miles later and it was back again... cleaned up my surfaces and I now have no shake at high speed, and I only have a slight shake while lightly braking... cleaning the surface between the rotor and the hub/bearing assy seemed to make the most difference.It is really bad right at the 65 mark and goes away a bit at 70. I can't see how a dirty surface would cause this terrible rattle.
Yes, Yes, No... if any of these surfaces are moving relative to each other while you drive, you're about to be driving a 3-wheeler (had it happen on a 300M)Thanks for the input, it is worth a shot. So you just use a wirebrush to clean the surfaces? Thats it? Does the dirty surface just make parts that should be moving smoothly "catch", causing the vibration?
