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
