I do have the symptoms of worn-out motor
mounts. But I don't know which one =( I have check everyone of them.
top, transmission, and behind the wheel. I really don't know what I am
looking for. My dogbones look like they are metal, and rubber surround the
bolts.... which part would be broken or cracked? Is it possible that
the sub-frame or that bracket that is attached to the motor could be
loose??
Cool, thanks for the help. I haven't actually
looked to see if there is
more than usual movement of the motor while
revving, but there is
definitely a knock and vibration at the beginning of
acceleration.
