Pontiac Montana Sway Bar Link
About Sway Bar Link
The sway bar of the vehicle is fastened to the car via a sway bar link. It is what connects the sway bar to the vehicle, this link is fastened with the help of a bushing and nut on one end and the other end is bolted to the suspension. The length of the sway bar links is usually between 4 to 4 inches, however it may vary in different vehicles, they are located at a 90 degrees angle to the sway bar.
What is the purpose of Sway Bar Link?
The sway bar helps in reducing the body roll during cornering; it is part of a car or trucks suspension system. It is also known as an anti-roll ball. When any vehicle is driven around a corner at a speed, the inside of the vehicle lifts as weight is transferred to the outside of the corner. The sway bar acts as a level and forces the inside wheel towards the ground which reduces body roll. The sway bar is a rigid piece of tubular steel that connects both opposing sides of the front/rear suspension. The sway bar link is a component within the sway bar, which secures the sway bar to the vehicle.
How Sway Bar Link Works?
When a car is driven around a bend on a road, the suspension of the outer wheels is compressed relatively more than the suspension for the inner wheel, this makes the inner wheel rise but the axle is attached to it lowers when the link is connected. Here is where the sway bar link comes into play, it transfers this change in the position of the control arm to the sway bar, the away bar then gets raised at the side. After undergoing torsion the sway bar gets twisted to be able to resist the movement which results in the spring on the other side expanding. In this way the sway bar link transfers a change in spring compression to the sway bar that raises the spring constant for the other spring. In this whole process the difference in compression gets cancelled out and the car is able to remain parallel to the road. The away bar link is also responsible to maintain the camber angle of the inner wheels in order to control its direction of motion. The sway bar links will come into functioning when either of the wheels out of the pairs present at the front or rear suffers a bump or a dip. When the level of the wheel axle traverses through the links it enables the sway bar to twist to equalize the compression in the two ends. This in turn result sin neutralizing the 'bump' or 'dip' among connected pair of wheels.
