Track aluminum control arm 31121096169

The automobile's control arm or wishbone is a nearly flat and roughly triangular suspension component (or sub-frame), that pivots in two places. The broad end of the triangle attaches at the frame and pivots on a bushing. The narrow end attaches to the steering knuckle and pivots on a ball joint. The upper control arm can clearly be seen at the top portion of the suspension components. The roughly A-shaped design with the top of the A near the tire and the bottom two points connected to the frame inside the body's space. Two such devices per wheel make up a double wishbone suspension, while one control arm per wheel makes up a part, usually the lower part, of a MacPherson strut suspension or of various other configurations.

Excessive noise. Given the crucial link between the suspension system and the chassis, it stands to reason that any problem with the control arms will impact safety. A loud banging or clunking noise may indicate that your control arms are going bad.

Poor steering control. Steering problems might not be due to steering components. If your control arms are starting to rust or become loose, you may notice a slight tremble in the steering wheel, especially at higher speeds - say, anything over 30 MPH. If an inspection of the universal joint, steering rack, alignment or similar steering issue comes up empty, the next logical choice is the control arm.

Wheel instability. If you notice a little bit of "wheel wobble" when your car is safely jacked up, it might not be a CV joint. Check the control arms for signs of wear and tear.
