What is a Shock Absorber MOT Fail?

Shock absorber MOT fails have been a common issue among car owners in the UK. Shock absorbers are essential components of a car’s suspension system, responsible for reducing the impact of bumps and vibrations on the road. They play a crucial role in maintaining the stability and safety of a vehicle, especially during sudden stops or turns.

During an MOT test, shock absorbers are thoroughly inspected to ensure they are in good working condition. If they are found to be faulty, worn out, or leaking, they will fail the test. This can be frustrating for car owners, as shock absorbers can be expensive to replace and may require additional repairs to the suspension system. However, it is important to note that a shock absorber MOT fail is not just an inconvenience, but a safety hazard that should be addressed as soon as possible.

Overview of MOT and Shock Absorbers

During the MOT test, one of the key components that are checked is the shock absorbers. These are the parts of the vehicle that are responsible for absorbing the shocks and vibrations that are produced by the road surface. They play a crucial role in ensuring that the driver and passengers have a comfortable ride and that the vehicle is stable and safe to drive.

The MOT test for shock absorbers involves checking the condition and performance of these components. The tester will inspect the shock absorbers for leaks, damage, and excessive wear. They will also check the rebound and compression of the shock absorbers to ensure that they are functioning correctly.

If the shock absorbers fail the MOT test, the vehicle will not be deemed roadworthy and will need to be repaired before it can be driven legally on the road. It is important to note that worn or damaged shock absorbers can affect the handling and stability of the vehicle, which can increase the risk of accidents.

It is recommended that the shock absorbers are checked regularly to ensure that they are in good condition. Signs of wear or damage include excessive bouncing, uneven tire wear, and a bumpy or uncomfortable ride. If any of these symptoms are present, it is important to have the shock absorbers checked by a qualified mechanic.

In summary, the MOT test for shock absorbers is an important part of ensuring that vehicles are safe and roadworthy. Regular checks and maintenance of these components can help to prevent accidents and ensure a comfortable ride for the driver and passengers.

Common Reasons for Shock Absorber Failure in MOT

During an MOT test, shock absorbers are checked to ensure that they are functioning correctly. If they fail the test, it is important to know why. Here are some common reasons for shock absorber failure in MOT:

1. Leaking Oil

One of the most common reasons for shock absorber failure is leaking oil. When the shock absorber starts leaking oil, it loses its ability to absorb shocks. This can cause the vehicle to bounce excessively and lead to a loss of control. During an MOT test, leaking shock absorbers will fail.

2. Damaged or Broken Mounts

Another reason for shock absorber failure is damaged or broken mounts. If the mounts are damaged or broken, the shock absorber will not be able to function correctly. This can cause excessive vibration and lead to a loss of control. During an MOT test, damaged or broken mounts will fail.

3. Excessive Wear

Shock absorbers are designed to wear over time, but excessive wear can cause them to fail. If the shock absorbers are worn out, they will not be able to absorb shocks properly. This can cause excessive bouncing and lead to a loss of control. During an MOT test, excessively worn shock absorbers will fail.

4. Incorrect Fitting

If the shock absorbers are not fitted correctly, they will not be able to function correctly. This can cause excessive vibration and lead to a loss of control. During an MOT test, incorrectly fitted shock absorbers will fail.

In conclusion, shock absorber failure during an MOT test can be caused by a variety of reasons. It is important to ensure that shock absorbers are regularly checked and maintained to avoid failure during an MOT test.

Inspection Criteria for Shock Absorbers in MOT

Visual Inspection

During an MOT test, the visual inspection of shock absorbers is a crucial step. The tester will check for any visible damage, such as leaks, corrosion, or broken mounts, which could compromise the proper functioning of the shock absorber.

Furthermore, the tester will check if the shock absorber is securely mounted to the vehicle and if there is any excessive movement or play. Any visible issues with the shock absorber may result in an MOT fail.

Functionality Test

The functionality test is a critical part of the MOT test for shock absorbers. The tester will check the shock absorber’s ability to dampen the vehicle’s movement by pushing down on the vehicle’s body. The tester will then release the vehicle, and it should return to its original position without bouncing or excessive movement.

If the shock absorber does not function correctly, it may result in an MOT fail.

Leakage Assessment

Leakage is another critical factor in the MOT test for shock absorbers. The tester will inspect the shock absorber for any signs of leakage, such as oil stains or dampness around the shock absorber.

If there is any evidence of leakage, it indicates that the shock absorber is not working correctly, and it may result in an MOT fail.

In summary, the visual inspection, functionality test, and leakage assessment are the three critical inspection criteria for shock absorbers in the MOT test. It is essential to ensure that your shock absorbers are in good condition to pass the MOT test and ensure the safety of your vehicle.

Consequences of Driving with Failed Shock Absorbers

Driving with failed shock absorbers can lead to a range of negative consequences, both for the vehicle and its occupants. Here are some of the potential issues that can arise:

Reduced Control and Stability

Shock absorbers play a critical role in maintaining control and stability while driving. When shock absorbers fail, the vehicle’s suspension system becomes less effective at absorbing bumps and vibrations. This can cause the car to bounce and sway, making it more difficult to control. In extreme cases, the vehicle may even become uncontrollable, putting the driver and passengers at risk.

Increased Wear and Tear on Other Components

When shock absorbers fail, they can cause increased wear and tear on other components of the vehicle’s suspension system. This can lead to more frequent repairs and replacements, which can be costly and time-consuming.

Reduced Braking Performance

Shock absorbers also play a role in braking performance. When shock absorbers fail, the vehicle’s weight can shift more dramatically during braking, leading to longer stopping distances and reduced control.

Increased Tyre Wear

Driving with failed shock absorbers can also lead to increased tyre wear. When the suspension system is less effective, the tyres are forced to absorb more of the impact from bumps and vibrations. This can cause the tyres to wear down more quickly, leading to more frequent replacements.

In summary, driving with failed shock absorbers can have a range of negative consequences for both the vehicle and its occupants. It is important to have your shock absorbers checked regularly and replaced if necessary to ensure safe and reliable driving.

Repair and Replacement Options for Failed Shock Absorbers

When a shock absorber fails its MOT, it is important to have it repaired or replaced promptly to ensure the safety and stability of the vehicle. There are several options available for repairing or replacing failed shock absorbers.

Repairing Shock Absorbers

In some cases, shock absorbers can be repaired rather than replaced. This can be a cost-effective option, especially if the shock absorber is relatively new and the failure is due to a minor issue such as a leak. However, it is important to note that not all shock absorbers can be repaired and it is essential to have a qualified mechanic assess the damage before attempting any repairs.

Replacing Shock Absorbers

If a shock absorber cannot be repaired or if it is too old or worn out, it will need to be replaced. There are several options available for replacement shock absorbers, including:

  • Original Equipment Manufacturer (OEM) parts: These are shock absorbers made by the same manufacturer as the original parts that came with the vehicle. They are designed to fit and function exactly like the original parts and are usually the most expensive option.
  • Aftermarket parts: These are shock absorbers made by third-party manufacturers. They are often less expensive than OEM parts and can offer improved performance or features, such as adjustable damping.
  • Reconditioned or remanufactured parts: These are used shock absorbers that have been refurbished and tested to ensure they are in working order. They are usually less expensive than new parts but may not offer the same level of performance or longevity.

Choosing the Right Replacement Shock Absorbers

When choosing replacement shock absorbers, it is important to consider factors such as the make and model of the vehicle, driving conditions, and personal preferences. A qualified mechanic can help recommend the best options based on these factors.

In conclusion, while a failed shock absorber can be a serious issue, there are several options available for repairing or replacing them. It is important to have a qualified mechanic assess the damage and recommend the best course of action to ensure the safety and stability of the vehicle.

Preventative Measures and Regular Maintenance

Regular maintenance of shock absorbers can help prevent MOT failures and ensure that they function correctly. Here are a few preventative measures that can be taken:

  • Inspect the shock absorbers regularly for any signs of damage or leaks. If any damage is found, the shock absorbers should be replaced immediately.
  • Check the suspension system for wear and tear, as this can affect the performance of the shock absorbers. Any worn or damaged parts should be replaced.
  • Keep the shock absorbers clean and free from dirt and debris. This can help prevent corrosion and damage to the shock absorber components.
  • Ensure that the vehicle is not overloaded, as this can cause excessive wear and tear on the shock absorbers.

Regular maintenance of the suspension system and shock absorbers can also help to prolong their lifespan and prevent costly repairs. It is recommended that the suspension system and shock absorbers are checked at least once a year, or more frequently if the vehicle is subject to heavy use or harsh driving conditions.

In summary, regular maintenance and inspection of the shock absorbers and suspension system can help prevent MOT failures and ensure that the vehicle is safe and roadworthy. By taking these preventative measures, drivers can avoid costly repairs and ensure that their vehicle is in good condition for years to come.

Legal Implications of MOT Failure Due to Shock Absorbers

When a vehicle fails its MOT due to faulty or worn-out shock absorbers, it can have legal implications for the owner. Driving a car with faulty shock absorbers not only poses a risk to the driver and passengers but also to other road users. Therefore, it is essential to address the issue as soon as possible.

According to the UK law, a vehicle must pass an MOT test to be considered roadworthy. If a car fails its MOT due to faulty shock absorbers, it is illegal to drive it on the road until the issue is resolved. Failure to do so can lead to a fine, penalty points on the driver’s licence, or even disqualification from driving.

Moreover, driving a car with faulty shock absorbers can also invalidate the vehicle’s insurance policy. If an accident occurs due to worn-out shock absorbers, the insurance company may refuse to pay for damages or injuries sustained in the accident. This can result in significant financial losses for the owner of the vehicle.

It is important to note that regular maintenance of a car’s shock absorbers can prevent MOT failure and potential legal implications. Car owners should have their shock absorbers checked regularly and replaced if necessary to ensure their safety and compliance with the law.

In summary, failing an MOT due to faulty shock absorbers can have serious legal implications for the owner of the vehicle. It is crucial to address the issue promptly to avoid fines, penalty points, disqualification from driving, and potential insurance issues. Regular maintenance of shock absorbers can prevent MOT failure and ensure the safety of all road users.
