Weird REAR Vibration/Shaking M35..

[tolete212]

'06 M35 Rear shaking when hittin 50 mph and up...the faster i go the stronger it gets. when i brake doesnt shake like if was the rotors so i believe the rotors are not the problem its only when i hit the gas.
and i checked the hub bearings too they're perfect and rims are perfectly balanced... what could be the problem??? the differential? idk help/// forgot to mention i did cut a layer on my rotors.

On a rear wheel drive car you could have and out of balance drive shaft. Your wheels and/or tires could still be a problem also. Were your wheels just spin blanced or road froce balanced. A bent wheel will sometimes still spin balance fine. How do you know all of your wheel bearings are fine?

i guess the bearings are fine because theres no sound coming out of it..theres a clicking sound when i put the car in Reverse.

I would still check on the bearings. I found out you can have a busted (out of alignment) bearing with no moaning noise. This happened with my last car 2004 pontiac Grand prix.

Had this problem when I had my 06 M35x...the problem for me turned out to be a frozen rear caliper...replaced the caliper and solved the problem...
