Control arms are essential suspension components that allow wheels to move up and down over bumps and road irregularities while maintaining tire contact with the road surface. The upper control arms work in conjunction with the lower control arms and are connected via ball joints and bushings that can wear out over time. Symptoms of worn control arms include clunking noises when hitting bumps, vibrations, steering wheel wobbling, and uneven tire wear. Professional wheel alignment is recommended after control arm replacement to ensure proper suspension geometry and tire wear patterns.
