Suspension components like Stabilizer Bar Links wear out over time often resulting in poor handling or a clunking sound over bumps. Check for excessive play in these bushings replace if necessary. Sway Bar links/stabilizer bar links connect the sway bar to the chassis and are an often overlooked replacement item. With age sway bar links, particularly links with ball joints, can develop play and will make knocking noises over bumps or when rocking the vehicle from side to side. If your sway bar links are in rough shape we recommend immediate replacement to restore your Volvo's handling. Always replace sway bar links in pairs.
