What does a rear shock absorber do?

Shock absorbers are responsible for your vehicle’s smooth drive over bumpy or uneven roads and are an essential part of your suspension system. Your shock absorbers are gas-filled tubes that are compressed by a piston, dissipating kinetic energy to provide a comfortable ride for you and your passengers, regulating the rebounding of the car.

Lexus

Lexus is the luxury division of the Japanese automotive manufacturer Toyota.

The Lexus brand was launched in 1989, is marketed in more than 70 countries worldwide, and has become Japan’s largest-selling make of premium cars.

How popular is Lexus in the United Kingdom?

For such a high-flying global leader, Lexus has a seemingly modest 156k cars on the road in the UK today.

Luxury executive vehicles for the discerning driver

In the UK, the Lexus brand focuses heavily on the NX and RX SUV models, it’s the fastest growing market for family cars after all; but each of the hatchbacks, saloons and coupés in its range come with the same high-level of luxury and sophistication for their £25–£76k price tags.

Lexus design and technology

Lexus was born to present itself as a luxury brand, something Toyota wasn’t in a position to market to their typical customer given their existing brand perception. To achieve a true luxury standard, they have targeted both vehicle development as well as their lavish presentation.

‘Lexus Musts’

Each vehicle has to achieve 500 specific must have standards known as ‘Lexus Musts’, all of which are to attain the high-end presentation and performance of a ‘true’ luxury marque.

Although they might not all be ‘Lexus Musts’ you can expect to find criteria such as leather seat stitching, smart key entry, remote touch control systems, surround sound and reduced cabin noise that utilises acoustic glass, in your Lexus vehicle. And the driving technology is just as impressive: Lexus introduced continuously variable transmissions, regenerative brakes, hybrid and electric fuel options, as well as vehicle stability and integrated dynamic handling management systems.

How often should shock absorbers need replacing?

You can expect shock absorbers to last at least 50k miles. Your owner’s manual may specify a different mileage or duration, as this figure is only a guideline. You should also have your shock absorbers checked after heavy contact with potholes, curbs or large rocks in the road.

The law, vehicle regulations and your MOT

What causes a shock absorber to stop working correctly?

If a shock absorber is leaking fluid, from malfunctioning or damaged seals, it will fail to operate correctly. A damaged, broken or bent shock absorber will also fail to operate as intended. This can happen through continual use, general wear or through damage from an accident. Some of the smaller internal parts will eventually wear out, which will prevent the complete component operating correctly.

Symptoms of a malfunctioning rear shock absorber

Excessive bouncing and an uncomfortable ride

If your car is providing uncomfortable ride quality and is bouncing excessively, it could be that your shock absorbers aren’t operating correctly.

The car feels unstable

When navigating corners or over uneven ground and your car feels unstable, this could also be due to suspension damage.

Driving over speed bumps is difficult

When driving over speed bumps or raised road elements causes uncomfortable and excessive bouncing, it is likely that your shock absorbers are damaged.

If you spot signs of leaking

Any puddles of oil-like fluid on the road around your wheels could be escaping from leaking shock absorbers.

If your wheels leave the ground

If your tyres lose contact with the road when driving over bumpy or uneven surfaces, then your suspension isn’t working properly and could be down to a faulty shock absorber.
