Mercedes MOT Reveals Worn Suspension Component at Our Walsall Garage

We had a Mercedes in recently for its MOT. The car looked well kept and the owner had no particular complaints about how it was driving. That is something we hear fairly often. Suspension wear creeps up gradually and by the time it gets serious most drivers have simply adapted to it without realising.

A Clear Knock on the Shaker Plate and Visible Play in the Front Suspension That Could Not Be Ignored

When we put the car on the lift and worked through the MOT checks we found significant play in one of the front suspension components. The movement was not subtle. We demonstrated it by hand and you could hear a knock as the component moved. That knocking sound also showed up on the shaker plate test, which is exactly what that test is designed to catch. When we jacked the wheel and checked again the play was confirmed. There was no grey area. The car had a mechanical fault that needed sorting before it could go back on the road.

A Worn Ball Joint or Tie Rod End Feels Like a Knock at Low Speed and Becomes a Loss of Control at High Speed

Suspension components like ball joints and tie rod ends are what keep your wheel in the correct position while you are driving. They carry the load of the vehicle and allow the steering and suspension to move as they should. When there is excessive play in one of these parts that control is compromised. At low speeds you might notice a knock or a vague feeling through the steering. At higher speeds, or in an emergency where you need to brake and steer hard at the same time, a worn component can behave unpredictably. In the worst cases a ball joint that has been left long enough can fail altogether. At that point you lose control of the wheel entirely. It is not a risk worth taking and it is not something we would let leave the garage unaddressed.

Worn Component Replaced, Car Reinspected and MOT Completed Once the Repair Was Done

The worn component was replaced, the car was checked over properly, and the MOT inspection was completed once the repair had been carried out. There is no shortcut with something like this. The part needed changing so that is what we did. Once it was sorted the car was safe and the owner drove away knowing the issue had been dealt with correctly rather than just noted and passed over.

If your car is making a knocking noise over bumps or through corners, if the steering feels vague or pulls to one side, or if you have not had the suspension looked at in a while, it is worth getting it checked. These things do not always make themselves obvious until they are already well worn. We carry out MOT inspections and suspension checks for customers across Walsall and the wider West Midlands and are always happy to take a look. Bring it in and we will tell you exactly what we find.
