Suspension Coil Spring
Your coil springs are not especially prone to failure, but if they have been cut, clamped, or heated to have the vehicle lowered, your 2001 Volvo V70 might benefit from replacing the strut springs. Excessive rust can make the springs more prone to failure. Contact your local Volvo service department to have your suspension system evaluated.
