Answer
Hi warren,

This is a very general question that can have many answers, but I will try to assist.

The first thought that comes to mind is, bent or damaged wheel, bad tire, flat spots on a front tire from being out of balance, missing wheel weight, or front suspension problems.


The front end needs to be inspected first. Are ball joints, idler arm (if so equipped) tie rods all tight?
The tires and wheels must be inspected and balanced.
Balancing will commonly reveal a problem with the tire or wheel.

The problem could be as simmple as getting thetires balanced.

Good luck!
