How Much does a Suspension Bushes Replacement Cost?
With every drive you make in your car, rubber or polyurethane components isolate moving parts to eliminate noise, reduce vibration, and keep you in control of your car.
These parts are known as suspension bushes and they are seldom spoken of.
During everyday use, suspension bushes are pieces of your car that go unnoticed. They experience wear over time, especially from rough road conditions, and will degrade due to exposure to grease, oil, and environmental fluids.
Suspension bushes normally last anywhere from 60,000 to 100,000km and sometimes more.
The average repair cost for suspension bushes replacement is $250 to $700, depending on which bushes need to be replaced and the type of car you drive. A mechanic will need to inspect your vehicle first to confirm this for you.
As a rule of thumb, the more movement bushes experience, the more wear will occur.

What are Suspension Bushes?
Under your car, moving parts like the control arms and stabiliser bar use suspension bushes to reduce wear on metal mounting surfaces.
There are also bushes used on your engine mounts to prevent vibration and allow slight movement. These bushes are constructed of synthetic rubber and/or polyurethane for durability and resistance to weathering.
In many situations, a metal sleeve is formed in the centre of the bushing and a metal ring on the outside helps suspension bushes hold their shape.
Cracking can form in the bushing material, or impact with the road can tear the bushing loose from the sleeve.
As well, suspension bushes can wear, causing suspension noise and affecting your car’s handling, thus they’ll need to be replaced.
