What were your symptoms? Vibration at what speeds?
Would the car pull strong still? Where could you feel it?
|
Vibration during hard acceleration particularly in third and above. I could feel it in the seat and the floor most of all.
|
I have this exact thing, i feel a alot of in the floor. So you replaced the bushing?
And it went away?
|
Yessir. Make sure they torque the nut properly. I had a clunking after they did it and they had to retorque.
|
Would aftermarket bushings have the same effect?
Also what year was your car? Did you pay out of pocket?
|
I'm not sure about the aftermarket. Car was a 3/2017 build M2. Did not pay out of pocket.
