LEMFORDER 37647 01

LEMFORDER 37647 01 – Premium Control Arm / Trailing Arm Bush

The LEMFORDER 37647 01 is a high‑performance suspension component designed for the Mercedes-Benz C-Class (W204) produced between 2007 and 2015. It serves as a control arm bushing, also known in various languages as brazo oscilante, silent block, or querlenkerlager. This part is critical for maintaining steering precision, reducing vibration, and ensuring the longevity of the vehicle’s front suspension.

Key Functional Attributes

• Load Distribution: The bushing absorbs vertical and lateral forces generated during cornering, braking, and acceleration, preventing excessive wear on the control arm and steering rack.
• Vibration Dampening: Its rubber‑metal construction reduces road‑borne vibrations transmitted to the chassis, enhancing ride comfort.
• Corrosion Resistance: The metal shell is treated with anti‑rust coatings, while the rubber core resists oxidation and UV degradation.
• Precision Fit: Manufactured to exact tolerances, it aligns perfectly with the control arm’s mounting points, ensuring optimal geometry.

Material Composition

The bushing is composed of a rubber core encapsulated within a stainless steel or aluminum alloy shell. The rubber is formulated with additives that provide:

• High resilience at low temperatures.
• Low friction coefficient to minimize wear.
• Resistance to oil, grease, and brake fluid.

Installation Compatibility

The LEMFORDER 37647 01 is engineered for:

• Front Suspension: Both left (driver) and right (passenger) sides.
• Vehicle Models: Mercedes-Benz C-Class (W204), including all variants from the 2007 to 2015 model years.
• Mounting Points: Control arm pivot, trailing arm attachment, and steering rack interface.

Installation Procedure Overview

1. Remove the existing bushing by loosening the mounting bolts on the control arm.
2. Clean the mating surfaces to eliminate debris or old grease.
3. Apply a thin layer of high‑temperature grease to the metal shell.
4. Insert the new LEMFORDER 37647 01 into position, ensuring proper alignment with the control arm and steering rack.
5. Tighten bolts to manufacturer specifications using a torque wrench.
6. Verify suspension geometry by checking camber, caster, and toe angles.

Performance Benefits

• Improved Handling: By maintaining consistent control arm positioning, the vehicle exhibits tighter steering response and reduced body roll.
• Extended Component Life: The bushing’s durability protects adjacent parts such as ball joints, tie rods, and steering rack bushings from premature wear.
• Noise Reduction: Rubber damping minimizes clunking noises that often arise from worn suspension bushings.

Maintenance Tips

• Inspect the bushing annually for signs of cracking, bulging, or oil seepage.
• Avoid over‑tightening bolts during installation; use a calibrated torque wrench.
• Replace the bushing if any deformation is observed to prevent steering instability.
