Mercedes models are popular for their sleek designs, sophisticated features, and reliability on the road. However, these characteristics are not possible without the various components that perform various functions to help keep the car running. One such component is the flex disc. Although it is important, it is also commonly overlooked.
The flex disc in a car can fail at any time and when this happens, it leaves a devastating effect on the car and its systems. However, understanding the common causes and the signs of failure can help you take better care of your car.
Common Causes of Flex Disc Failures in a Mercedes
The flex disc is a rubber coupling material that holds the driveshaft with the transmission (at the front) and the driveshaft with the differential (at the rear side). Its main function is to absorb your car’s vibrations and prevent engine noises.
However, the flex discs in your Mercedes can fail due to the following reasons:
- Aging: This is one of the major causes of failures in most car systems and sometimes, it is unavoidable. The older your car gets and the more mileage it has, the more likely it is to experience wear and damage as a result of frequent or continuous use. However, with proper maintenance, you can reduce the chances of this happening.
- Material Degradation: Another major cause of failures in the flex disc of any car is the degradation of its material. The flex disc is made of rubber material and over time, with increasing stress, exposure to heat, and other external factors, the rubber material will constantly expand and contract, leading to wear and damage.
- Contamination: The presence of contaminants in the flex disc area can also be a cause for its failures. For example, if oil, fluid, or other chemical substances leak onto the flex disc, the rubber material may become affected, degrading in the process and leading to a failure in the disc’s functions.
- Physical Impact: This is a major cause of flex disc failures, especially for careless drivers. Due to the location of the flex disc, it is constantly exposed to various external factors. Hence, if you frequently drive through rough road surfaces or hit bumps, sooner rather than later, your car’s flex discs will get affected and eventually fail.
Symptoms of a Failing Flex Disc in Your Mercedes
If you are wondering how to recognize when your car’s flex disc is faulty, here are some signs to help you.
- Trouble Shifting Gears: If you notice that it has become more difficult to shift the gear in your car especially when shifting from park to drive or park to reverse, then there is likely a problem with the flex disc. This is possible because the flex disc holds the driveshaft to the transmission and if it is faulty, then the transmission system can be affected too.
- Unusual Vibrations and Loud Sounds: Another sign of flex disc issues in a car is when your car begins to vibrate excessively or make loud knocking sounds especially when you try to increase the speed. The main purpose of the flex disc is to prevent noise and vibrations when driving. If it fails to do this, then there is an obvious problem.
- Obvious Signs of Wear: Another way to tell that your car’s flex disc is faulty is when you notice signs of wear or damage on the flex disc body on inspection. This is why it is important to conduct regular checks and inspections on your car components. Hence, if you see signs such as cracking, missing sections, or torn rubber pieces, then the flex disc is bad and can fail.
