Anti-Roll Bar Links — Knocking Noises and Replacement

Worn anti-roll bar links cause a knocking noise from the suspension on uneven roads and allow excessive body roll during cornering.

The anti-roll bar connects the left and right suspension to reduce body lean during cornering. The drop links that connect the bar to the suspension strut are a common wear item, especially on vans that carry heavy loads or are driven on poor roads. Symptoms include a metallic knocking or clunking from the front or rear suspension when driving over bumps or turning, and increased body roll in corners. Replacement is inexpensive and straightforward, but if left too long, worn links can cause accelerated wear to other suspension components and bushes.
