How can I tell the suspension springs are worn out?
The signs of worn suspension coil springs are a reduced ride height, vibration, knocks, jolts when driving – especially when driving over bumps – and body roll in corners. The car sways from side to side when braking or accelerating abruptly, or sags on one side. In general, driving comfort is reduced. During inspection, you can see rust spots and traces of contact between the coils of the spring.
Is it safe to drive with a broken coil spring?
No, since the absence of even a small part of the component results in increased loads on other parts of the suspension: shock struts, shock absorbers, strut mount bearings, and bump stops. This leads to their premature wear and so to impaired vehicle handling.
Can I replace only one spring?
No. Coil springs should be replaced in pairs. The properties of a new and a used part may differ significantly, which adversely affects the suspension performance. In addition, failure of one usually means the other will fail soon.
