C219 CLS63 Rear vibration at speed - not rotors - HELP!
Hopefully someone can shed some light on this frankly exhausting subject that I've been battling with for months.
The car is an 80,000 mile CLS63 2006. Violent high frequency vibration from the rear wheels only during braking any speed over 80mph. Also, rear wheels feel imbalanced over 90mph and get worse and worse.
Taking a technician out in the car to replicate the fault has been hit and miss. It does it 100 times out of 100 for me. When I drove it up to speed with the tech on board and hit the brakes it was smooth as butter on every run. Typical.
Work so far:
-3 sets of brand new rotors/discs and pads - OE quality, replaced back to back when I assumed it was just bad luck and the new parts were bad
-New Continental tyres
-Wheels balanced up perfectly - checked and re-checked 3 times
Prop bearings checked, no noticeable bush/ball joint wear, gearbox mount seems good.
What am I missing? Any ideas from someone more knowledgable and experienced than I would be greatly appreciated as I'm at my wits end with what is otherwise a spectacular car.
