What is the reason for the abnormal noise in the front shock absorber of the Mercedes-Benz GLC?
3 Answers
The abnormal noise in the front shock absorber of the Mercedes-Benz GLC may be caused by damage to the dust cover of the shock absorber, allowing foreign objects to enter the shock cylinder. In this case, it is necessary to inspect the shock cylinder. Below is some relevant information: 1. About Mercedes-Benz: The Mercedes-Benz GLC is a mid-size SUV under the Mercedes-Benz brand. The dimensions of this car are 4764 mm in length, 1898 mm in width, and 1642 mm in height, with a wheelbase of 2973 mm. 2. In terms of power: This car is equipped with two engines, one is a low-power version 2.0-liter turbocharged engine, and the other is a high-power version 2.0-liter turbocharged engine. (1) The low-power version 2.0-liter turbocharged engine has a maximum power of 197 horsepower and a maximum torque of 320 N·m. It can output maximum power at 6100 rpm and maximum torque between 1650 and 4000 rpm. This engine is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block. (2) The high-power version 2.0-liter turbocharged engine has a maximum power of 258 horsepower and a maximum torque of 370 N·m. It can output maximum power at 6100 rpm and maximum torque between 1800 and 4000 rpm. This engine is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block.
When it comes to the front shock absorber noise issue on the Mercedes-Benz GLC, I've pondered this problem multiple times. There are quite a few common causes, such as aging shock absorber cores leaking oil, where the noise becomes more noticeable after long-distance driving. The rubber bushings in the suspension system tend to wear out over time, leading to creaking sounds on bumpy roads. Loose or deformed components connecting the springs are also not uncommon, especially in high-end SUVs like Mercedes-Benz, where the design is so precise that even a minor flaw can be magnified. I've tried inspecting it myself by driving slowly in circles to listen for the source, but most cases still require professional shops with diagnostic equipment. Don't delay repairs, as this could increase risks like unstable steering or tire blowouts. During regular maintenance, ask the technician to focus on the suspension. Although replacing parts can be costly, it's worth it for safety. In short, addressing the issue early saves a lot of hassle.
The rattling noise from the shock absorbers on the Mercedes-Benz GLC is indeed annoying, likely caused by component fatigue – such as deformed spring buffer rubbers that creak on gravel roads. Another contributing factor could be damaged internal seals in the shock absorbers leading to oil leakage, which makes bumps more noticeable at high speeds. As an owner, I recommend first ruling out simple issues: check if the tire pressure is uneven or if the vehicle is overloaded, as uneven pressure can also cause noise. If unsure, avoid DIY disassembly—Mercedes OEM parts have high standards, and improper repairs might damage the control arm. Instead, head straight to an authorized service center for a chassis inspection, where they can accurately diagnose the issue and replace parts. For prevention, avoid rough roads and replace bushings regularly to extend component lifespan, saving money and ensuring safety.
