How to Check & Maintain Your Suspension

Keeping your vehicle performing efficiently for as long as possible will save a lot of stress and money. Suspension plays an integral role in this, both helping a car's parts work well together, as well as ensuring they each experience as little impact and damage as possible during use. The suspension is therefore a crucial component to maintain overall functionality, and owners must frequently inspect them to ensure they’re in adequate condition.

To help, suspension issues can cause certain indications that they need replacing. Becoming familiar with what these signs are can help ensure you check and maintain your suspension regularly, keeping your car running smoothly and protecting its parts. Pro Speed Racing supplies a range of car suspension components, and with our extensive experience in the industry, we are well equipped to provide insight into your suspension inspection and maintenance schedules.

3 tips to check and maintain your car suspension

Measure the height of your wheels

With a tape measure, you can measure the height of your front wheels regularly to assess the condition of your suspension. Start with the distance between the top of the tyre to the bottom of the bumper on both wheels. If there is a large variance (above 2.5 centimetres) between the lengths of each side, this may mean that the lower side has an issue with its suspension. However, if the distances are similar, it’s still possible that both suspension sides have similar wear issues and have remained the same height.

Visually inspect the strut mounts

Without much effort, you can inspect the strut mounts to detect damage or rust that could be inhibiting the suspension. Open the bonnet of the vehicle and actively look for the towers located on each side - they typically run from above each wheel through to the fender, stabilised by nuts and bolts. When located, examine their condition, considering that clean and uniform mounts mean they’re in a healthy condition. If you find damage or rust or notice they’re loose, you should have them checked and repaired in order to maintain the condition of your suspension.

Inspect components from underneath the car

A more demanding but effective way to monitor the condition of your vehicle's wheels and suspension is to lift it using a car jack and undertake a visual inspection from underneath. Be careful to follow the guidance in the owner’s manual when lifting your car with a jack and always adhere to the designated jack points to ensure a safer lift. You can also use a torch to increase visibility when inspecting under the car.

Once in position, identify the rubber bushings on each wheel that separate the metal parts of suspension systems to reduce their wear. Inspect the bushing for tears, cracks or a non-uniform shape that indicates damage and the need to be replaced. You can also determine their colour, which is typically black, but turn grey when they wear over time.

As rubber bushings mean that the metal components don't scrape together, when bushings are in poor condition, suspension can be damaged quickly. If you notice any problems with the bushings or any are missing completely, it's important to have your suspension inspected professionally and replaced if necessary.
