Control arms, or A-arms, connect the knuckle or solid axle to the body of the vehicle. Control arms typically
contain bushings that absorb impact and vibration; as well as ball joints that allow the suspension to move up
and down. Over time the bushings or ball joints in the control arm will become worn and will need replacement.
It is often easier and faster to replace the entire control arm than replace individual components.
The upper control arms include bushings to absorb the small impacts, like the cartilage in your knee or
elbow joints. Aftermarket control arm bushings can be made from polypropylene or polymer, a stiffer
substance that can tighten up steering response and handling, and will last the life cycle of the vehicle.
