The odd part of it is the vibration is not steady. It seems to vibrate
in a rythymic pattern. When I accelerate up to 65 and beyond it starts
vibrating
The rhythmic pattern you are getting is caused by both front wheels being
out of round or out of balance. One tire is slightly larger that the other so
as
they roll, they go in and out of phase giving what you describe as a
rhythmic pattern. The sensitivity of a car to wheel force inputs will be
greater if
the shocks are worn or their mounting bushings are loose.
Loose or worn suspension bushings will also increase sensitivity. The rubber
bushings in the Tiger suspensions are tuned to about 65 MPH. Hard plastic
bushings will increase the natural frequency beyond the normal driving range.
So the recommended fixes are;
* Replace the shocks and mounting bushings
* Replace the tires, balance them and check for bent wheels
* Replace Suspension bushings with hard plastic and align
