Causes Behind the Classic Flex Disc Failure in Your Mercedes
The Mercedes Benz is distinguishable by its trademark: the three star symbol. This symbol represents air, land, and sea. However, your Mercedes is also known for its optimal driving experience, luxury design, amazing selection and world class performance.
Even these high-end automobiles suffer from the occasional mechanical or engineering breakdown. No vehicle is immune to problems or the need for potentially significant repairs. The classic flex disc is an often overlooked component of a Mercedes that can deteriorate over time. If issues arise in relation to the disc, it can lead to severe and costly repairs. Let’s dive deeper into what the disc actually is, the purpose it serves and reasons that it may malfunction.
What is the flex disc?
The flex disc is also known as a giubo. The giubo, in simple terms, is a coupling device that is composed of rubber. There are actually two flex discs in the Mercedes; the front disc connects the transmission to the driveshaft and the rear giubo connects the driveshaft to the differential.
What Does the Flex Disc Do in Your Mercedes?
Both of the flex discs in your automobile serve two distinct purposes during operation. The first is to isolate and protect the drive shaft from vibration while the transmission transfers power to the differential. The second important job of the giubo is to absorb the excessive torque that occurs during accelerating or decelerating. When either of these is done more than normal or at above average force, the torque will become more extreme.
Why do flex discs fail?
Let’s take a closer look at why the flex discs may fail in your vehicle.
- Age of Your Car. As a car gets older, many components tend to show signs of wear and tear. Over time, they can become faulty and need to be repaired or replaced. The flex disc is designed to last approximately 200,000 miles in your Mercedes. However, extreme driving conditions can alter this scenario. Your automobile will experience a lot of suspension activity thus causing the nuts and bolts of the disc to work their way out or become stripped.
- Alignment of the Drivetrain. The misalignment of the drivetrain in your vehicle can lead to a number of serious issues. One of the most common of these is the negative result it has on the flex disc. The misalignment causes the rubber disc to stretch beyond its normal flexibility. This extreme stretching leads to tears, rips, cracks and other detrimental consequences.
- Environmental Elements and Extreme Heat. Since the flex disc is composed of rubber, it is more susceptible to damage caused by the elements. Heat is one of the most damaging as it causes the rubber to expand and contract. After this is done over and over, it will lead to the breakdown of the disc. Other elements such as sand, salt and dust that are routinely encountered in certain environments can also eat away at the giubo over time.
When your Mercedes is in need of repair, it is best to have it evaluated by professionals. Being aware of unusual sounds or performance issues is key to having issues addressed early, keeping the potential severity and cost of such repairs to a minimum. It is also important to stay on top of the regular maintenance schedule for your vehicle.
