Suspension Coil Spring - Repair or Replace
Your coil springs are not especially prone to failure, but if they have been cut, clamped, or heated to have the vehicle lowered, your 2011 Lexus GX 460 might benefit from replacing the strut springs. Excessive rust can make the springs more prone to failure. Contact your local Lexus service department to have your suspension system evaluated.
