Part of the Suspension and steering guides.

Springs carry the load; bushings and mounts decide how much of the road you feel. These guides cover coil, leaf and air spring selection, press-fit and bushing quality, and the mount wear that turns a comfortable car into a noisy one.

Coil springs, leaf springs and air suspension

Spring rate, free length and vehicle load decide the correct spring far more than the model listing does.

Bushings, press fit and NVH

Bushings are a press-fit component; installation quality determines service life.

Frequently asked questions

Can I replace a coil spring without replacing the strut?

Yes, but the strut should be inspected while it is apart, and the spring must match the vehicle’s load and rate. Mixing a new spring with a worn damper often produces a ride complaint.

Why do new bushings sometimes make noise?

Usually installation. A bushing that is twisted rather than seated, or pressed in dry or at the wrong depth, will bind and squeak. Press-fit quality matters as much as the compound.
