Vehicles that are equipped with oversized tires have excessive weight at the front wheels — weight that the manufacturer didn’t intend. This can produce excessive steering feedback in a rapid frequency, which can be uncontrollable. It is called a ‘death wobble’ due to its frightening and often dangerous shaking. A steering damper assists in solving a death wobble, and many trucks and SUV’s are equipped with one. A steering stabilizer absorbs much of the vibration that causes a death wobble due to the dampening effects of a fluid-charged cylinder. It's design is essentially that of a suspension system’s shock absorber, which eliminates bounce in a vehicle. The steering stabilizer may be lighter duty than necessary for applications with oversized wheels, or it may be worn out.
