What are rubber bushings used for on suspensions?
CARS.COM — Bushings are cushions made of rubber, polyurethane (often shortened to “poly” or “urethane”) or other materials. They’re mounted on car suspension and steering joints to absorb road bumps, control the amount of movement in the joints and reduce noise and vibration.
What is the purpose of rubber bushings?
A rubber bushing, sometimes simply called a bushing, is a kind of vibration isolator. Its main purpose is to serve as an interface between two parts, acting as a buffer and absorbing some of the energy produced by the interaction of two parts.
Do shock absorbers come with bushings?
Most shocks will come with fresh hardware, locknuts and rubber bushings, which I recommend replacing even if the old ones look fine. Remove the upper bolt from the shock’s central damper rod and remove the shock from the vehicle.
What is the best material for suspension bushings?

|---|---|---|
| Hardness | Harder and less pliable | Softer and more pliable |
| Lifespan | Life of vehicle | Same as original bushing |
| Squeaking | Small chance of squeaking | No chance of squeaking |
| Maintenance | Greasing every 4-5 years | None |
Can shock bushings be replaced?
Often made from steel with a nylon / PTFE coating, the bushings inside the eyelets of your rear shock are designed to wear over time, and thus – they are an easily replaceable part with the right tools and a little care. …
Are bushings part of the suspension?
Bushings are rubber pads that are attached to a vehicle’s suspension system. Bushings can be found on any component along the suspension where two parts of metal form a joint. The purpose of the bushings is to prevent the metal surfaces from grinding against one another and causing unnecessary stress and friction.
What type of rubber is used in car bushings?
Comparison of Rubber and Polyurethane Bushings
