How to avoid failing your MOT on suspension

MOT Advice

Suspension is one of the most common reasons for a vehicle to fail its MOT. It’s system has many moving parts and the constant movement means they can eventually wear out. One of the things that can damage your suspension is hitting a pothole, if this has happened it would be a good idea to get your vehicle checked out as it may have affected your suspension, wheel alignment or tyres.

Unless you confidently know your way around a car, van or motorbike it is strongly advised that you consult a professionally trained technician if you suspect you have a problem with your suspension. If you are unsure, we have outlined some of the issues which could indicate your suspension has gone and needs repair work:

Bumps in the road

If you can feel every bump in the road or the car jerks when the road surface is uneven it may be time to visit a garage to get your suspension looked at.

Difficulty turning

If you experience a drift or pull when you’re turning it could mean the shocks have worn out. Shocks are what keep the vehicle balanced against the force of a turn so it is imperative this is taken to a workshop as soon as possible to get it looked at by a vehicle technician.

Uneven tyre treads

If you begin to notice one tyre is wearing more or starting to bald on the same axis as the other, it could be an indication that your suspension is uneven. Disproportionate amounts of pressure are applied to the tyres when suspension is uneven and should be readjusted as soon as possible to prevent accelerated wear of your tyre.

Dips when stopping

It isn’t just your brakes that can affect your ability to stop. If your vehicle dips forward when you apply the brakes firmly, this could be a sign that your suspension shocks are worn out. It is important to go and get this checked out as over time it can increase the time it takes you to stop leading to only more problems.

Oily shocks

If you can get under your vehicle safely to have a look at the suspension system and notice the shocks are greasy or oily, there could be a chance they are leaking fluid. This will impede their performance so it’s advised you go visit a vehicle technician as soon as you can to get them checked out professionally.

The bounce test

If you suspect you do have a problem with your suspension you could perform the bounce test. The test is not 100% accurate, but could prove helpful when other symptoms are taken into consideration.

Park your car in a safe place and remove the keys from the ignition. Firmly push on the bonnet, but be careful not to damage the bodywork. When you release your weight the car should return to its original position without further bouncing. If it does continue to rock or bounce this could mean your shock absorbers are becoming weak. This same test can be carried out on the rear suspension by firmly pushing on the boot or hatchback.

It is always recommended you have a professional give you an accurate diagnosis if you suspect you may have an issue with your vehicle. Book in online with one of our great garages today.
