Drive Train Axles Bearings problem
2007 Infiniti G35 6 cyl All Wheel Drive Automatic 42000 miles
HI, I just recently bought new set of michelins pilot sport a/s plus for my 2007 G35x sedan with OEM wheels/rims. A week after this, I installed new sport rotors from EBC (3GD Sport) and brake pads from Bendix (ceramic CT3).
My problem is that the steering wheel was vibrating at 60-75ph. I had the tires and wheels road forced balanced 3 times but the vibration is still there. So I went ahead and checked all brake parts and suspension parts for looseness and play. No there was no play in either those parts nor the hub bearings. So I put the wheels back on, this time putting them on very flush against the rotors hub, tightened the lugs by hand before lowering the car and torqing the lugnuts to 80 ft/lb.
This remounting of the wheels helped a little bit. The shimmying was very small and not too noticeable now. I think the wheels were not mounted fully flush against the hub/rotors.
Ok so, another week after this, I'm experiencing an excessive road feel in the steering wheel and shift knob (very high frequency vibration?) At city driving speeds. Also even on the floor boards, I can feel vibrations with my left foot. These vibrations can be felt accelerating from 0mph - any speed. As I push the gas pedal to accelerate, I can feel this "excessive road"/high frequency vibration in the pedal traveling through the steering wheel and the shift knob and a little bit in the seat.
Could this be an engine mount? Or a worn bushing? Or stuck caliper maybe (the brakes are very smooth by the way, no pulsations or feedback from the brake pedal)?
Please help. This is getting to be very annoying. I cannot drive for more than 5 mins without my hands becoming numb.
have the same problem?
