A control arm bush is made from a tough rubber and installed on the front and rear control arms of vehicles to ensure that they are fitted securely to the suspension system. The control arm of a vehicle is responsible for allowing the smooth movement of tyres in line with a vehicle’s body.
The control arm bush is a crucial part of the suspension system and should be maintained like any other part of the vehicle. Should one fail, the control arm will have more give and could potentially fail, meaning that the drive will be very uncomfortable over bumpy surfaces.
Because of the rubberised material of the control arm bush it is possible that it could crack and deteriorate, particularly if it comes in to contact with oil or dirt. If one of these bushes becomes worn it should be replaced quickly as vehicular damage can escalate.
You may notice that your tyres are not wearing evenly, or wear quickly or the drive has become more awkward and bumpy. If this is the case you should also examine the control arms for signs of damage and wear and replace as necessary.
