Control Arm Bushings
Rubber or polyurethane sleeves pressed into the control arms to pivot smoothly, absorb road shocks, and maintain wheel alignment.
Control arm bushings are small but crucial suspension components that act as pivots connecting the control arms to the vehicle chassis. Typically consisting of a rubber or polyurethane sleeve bonded to inner and outer metal sleeves, they allow the control arms to swing up and down as the wheels travel over road irregularities.
In addition to allowing pivoting movement, these bushings isolate the passenger cabin from harsh road vibrations, tire noise, and impacts. Because they are constantly subjected to twisting forces, road grime, salt, and heat, the rubber eventually degrades, dry rots, tears, or sags.
Worn control arm bushings can cause the wheels to shift alignment under braking or acceleration, leading to steering wheel shimmy, uneven tire wear, pulling to one side, and loud clunking noises over bumps. Replacing worn bushings (or the entire control arm assembly) restores steering precision and a quiet ride.
