The suspension arm, also called the track control arm or wishbone suspension, is attached to the wheel and allows you to direct it and keep it square to the ground. Wishbone suspensions are attached directly to the chassis of the car with a silent block and to the wheel via a ball joint.
A damaged wishbone can cause premature wearing of the tyres, shock absorbers and brake pads, which can lead to poor traction and even loss of control.
A broken wishbone can cause total immobilisation of the vehicle, as the wheels can no longer turn.
Contrary to the brake pads, the suspension arm is not considered to be a wearing part. Only accidents or small repeated impacts can damage the part. However, if the wishbone is being replaced, be aware that it rarely breaks on its own. The silent block is the part that is most usually subject to pressures. So, in order to know for sure if a suspension arm is damaged, check the state of its component rubbers.If these display cracks or tears, it means it’s time to replace your suspension arm!
The wishbone suspension should be changed:
As you now know, each wishbone suspension is linked to a wheel, with either two in front of it or two behind it. Like brake pads or shock absorbers, wishbone suspensions are changed in pairs, meaning that if you’re changing the right suspension arm, you’ll also want to change the left one.
