Rubber arm bushes (also known as control arm bushings) are crucial suspension components that cushion and connect the control arms to the vehicle’s frame or subframe. Made from durable rubber or a rubber-metal blend, these bushes help absorb road shocks, reduce vibration and allow controlled movement of the suspension parts during driving. This results in a smoother, quieter ride and better handling.

Over time, rubber bushes can wear out, crack or harden due to heat, stress and exposure to road elements. Worn bushes can cause clunking noises, uneven tire wear, poor wheel alignment and a loose or unstable feel while driving. Replacing them restores proper suspension geometry, improves comfort and enhances vehicle safety and performance. They’re a small part with a big impact on ride quality.
