Full details

This Febi 72-3442 Rubber Buffer is an essential component for Mercedes-Benz owners aiming to restore optimal rear suspension performance and comfort. It effectively dampens coil spring movement, contributing to a smoother ride and reduced noise, though professional installation is strongly recommended due to the technical nature of suspension work. Key features include its precise 17mm height, 4-knob coil spring design, and broad compatibility with specific C-Klasse, E-Klasse, GLK, SLK, and CLK models.

FAQs

What is the primary function of this rubber buffer?

The Febi 72-3442 Rubber Buffer primarily functions as a cushion for the rear coil springs, absorbing impacts, reducing harshness, and preventing metal-on-metal contact within the suspension system. This improves ride comfort and protects other components.

When should I consider replacing my vehicle's rubber buffers?

You should consider replacement if you notice increased harshness over bumps, excessive thumping or clunking noises from the rear suspension, or if visual inspection reveals cracks, deterioration, or complete absence of the original buffer.

Is this part suitable for the front suspension?

No, this specific Febi 72-3442 Rubber Buffer is designed exclusively for the rear axle of compatible Mercedes-Benz models. Different parts are required for the front suspension.

How can I confirm this part is compatible with my Mercedes-Benz?

To confirm compatibility, match your vehicle's model, year, and chassis type with the listed compatible models. Crucially, verify your VIN against the specified ranges (F369714, A384234) and cross-reference the OEM part numbers 2103250484 or A2103250484 with your existing part or vehicle documentation.

Does replacing this rubber buffer affect the vehicle's ride height?

A worn or missing rubber buffer can cause a slight reduction in ride height and increase suspension travel. Replacing it with a new 17mm buffer like the Febi 72-3442 will restore the factory-intended ride height and suspension characteristics for that component.

What is the expected lifespan of this rubber buffer?

The lifespan of a rubber buffer can vary depending on driving conditions, climate, and vehicle usage. However, as a high-quality component, it is designed for long-term durability. Regular inspections during service intervals will help determine if replacement is needed.

Troubleshooting

Continued harshness or thumping noises from the rear suspension after replacement.

While this rubber buffer will alleviate issues caused by a worn buffer, other suspension components (e.g., shock absorbers, coil springs, control arm bushings) could also be worn. Have a professional inspect the entire rear suspension system to identify other potential culprits.

The rubber buffer does not seem to fit correctly during installation.

Carefully double-check the product's compatibility with your specific Mercedes-Benz model, year, and VIN. Ensure you are installing it on the rear axle and that the coil spring design matches. Refer to the associated part numbers (2103250484, A2103250484) and your vehicle's specifications.

The new rubber buffer shows signs of premature wear (e.g., cracking, splitting) shortly after installation.

This could indicate an underlying issue with another suspension component causing excessive stress on the buffer. Inspect the coil springs for damage or incorrect seating, and check shock absorbers for proper function. Ensure the vehicle's suspension is not overloaded regularly.

Difficulty in compressing the coil spring during installation.

Working with coil springs requires specialized tools like a spring compressor. Attempting to install without the correct tools is unsafe and can damage the component or cause serious injury. It is strongly advised to seek professional assistance.
