Just got back from driving the car after putting in a new wheel bearing in the front. Of course that did nothing for the vibration, as I figured it wouldnt.
So next question..could a bad motor/transmission mount cause this vibration? And if it did, wouldn't it stop/change if I put it in neutral on the interstate?
The engine seems to have a good amount of movement...if I put it in drive with my foot on the brake and give it some gas the one side of the motor lifts up a good amount..maybe this is normal.
I can not think of anything else that could cause this..all bearings are good, all rotors good, all wheels road force balanced and good, I just don't know where else to look. The vibration is bad enough that if I look over at the headrest of the passenger seat when it starts vibrating, the seat is actually shaking..I can't drive 1800+ miles like that.
Never had this problem a few months ago before I put it up for sale, so of course it has to do it now..
