Mercedes MOT Reveals Worn Suspension Component at Our Walsall Garage
We had a Mercedes come into us recently for its MOT. On the face of it the car looked well kept, dark in colour and in decent condition overall. The owner had no particular complaints about how it was driving, which is something we hear fairly often. A lot of suspension wear creeps up on you gradually, and by the time it gets serious, you have simply adapted to it without realising.
What we found during the inspection
When we put the car up on the lift and worked through the MOT checks, we found significant play in one of the front suspension components. Whether it was a ball joint or a tie rod end, the movement was there and it was not subtle. We demonstrated it by hand and you could hear a knock as the component moved. That knocking sound also showed up during the shaker plate test, which is exactly what that test is designed to catch. When we jacked the wheel and checked it again, the play was confirmed. There was no grey area here. The car had a genuine mechanical fault that needed sorting before it could go back on the road.
Why this kind of wear is a problem and what happens if it is left
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 situation where you need to brake and steer hard, a worn component like this can behave unpredictably. In the worst cases, a ball joint that has been ignored long enough can fail altogether, and at that point you lose control of the wheel entirely. It is not a risk worth taking, and it is certainly not something we would let leave the garage unaddressed.
How we sorted it
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 could drive away knowing the issue had been dealt with correctly rather than just noted and passed over.
If your car is making a knocking noise when going over bumps or through corners, if the steering feels vague or pulls to one side, or if you have simply 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 we are always happy to take a look. Bring it in and we will tell you exactly what we find.
