Suspension bushes and tyre health

A common MOT failure is excessively worn tyres and it is amazing how many tyres we see that have worn unevenly, and prematurely. It is rarely a fault with the tyre and is usually a suspension issue.

One of the most common suspension issues we see in the workshop is ‘bush wear’. In fact, bush wear is a common MOT failure and you may have already experienced this problem in the past.

Suspension bushes are rubber mountings that link your vehicle’s suspension arm to the chassis. The rubbery material is vital for absorbing movement and vibration when travelling on the road. If all suspension components had rigid metallic links and hinges, the ride would be harsh, noisy and very uncomfortable, so these rubber bushes are vital for a smooth and enjoyable driving experience.

And, because it’s your vehicle’s suspension that holds the wheels in place, worn or soft bushes can have a detrimental effect on wheel alignment and ultimately lead to premature tyre wear.

As cars have advanced over the years, wheel alignment has become crucial for the safety of road users. Modern vehicles, with traction control and ABS, must perform to strict guidelines and tolerances to ensure road users’ safety. If the vehicle does not drive or brake correctly the ABS/TCS may not be able to prevent an accident.

So, if you notice; uneven tyre wear; or your steering wheel is not pointing straight when driving straight; or the car pulls to the left or right while driving or braking; or you hear a knocking coming from your suspension, you should take it to your garage for a suspension check and wheel alignment, as soon as possible.
