LEMFÖRDER 37988 01 Control Arm-/Trailing Arm Bush For Mercedes-Benz METRIS BOX

LEMFÖRDER 37988 01 Control Arm-/Trailing Arm Bush

The LEMFÖRDER 37988 01 Control Arm-/Trailing Arm Bush is a precision‑engineered suspension component designed for the Mercedes‑Benz V‑Class (W447) and related models such as the VITO, EQV, and V‑CLASS vans. It serves as the critical interface between the vehicle’s control arm or trailing arm and the chassis, absorbing road shocks while maintaining alignment and ride comfort.

Key Design Features

• High‑grade rubber compound: The bush is crafted from a durable elastomer that resists wear, temperature extremes, and chemical exposure. This ensures long‑term performance even under heavy load conditions.
• Precision molded geometry: Each component is manufactured to exact tolerances, guaranteeing a snug fit within the mounting cavity and eliminating play or vibration.
• Dual‑side compatibility: The part is available in left‑handed and right‑handed versions, allowing seamless replacement on either side of the vehicle without cross‑compatibility issues.
• Outer and rear axle application: Designed specifically for the outer control arm or trailing arm on the rear axle, it supports both longitudinal and lateral forces during cornering and braking.

Material Composition & Durability

The bush combines a rubber core with an inner steel reinforcement. The steel inserts provide structural strength while the rubber encapsulation absorbs impact energy. This hybrid construction delivers:

• Reduced noise, vibration, and harshness (NVH) levels.
• Extended service life compared to conventional plastic bushings.
• Resistance to oil, grease, and road salts that can degrade softer materials.

Vehicle Compatibility Matrix

The component is engineered for the following Mercedes‑Benz platforms:

Installation Procedure

Replacing the control arm or trailing arm bush is a straightforward process that can be completed with basic hand tools. Follow these steps for optimal results:

1. Safety first: Raise the vehicle on jack stands and secure it to prevent accidental movement.
2. Remove the old bush: Use a pry bar or impact driver to detach the rubber bushing from its mounting point. Carefully extract any debris or remnants.
3. Clean the mounting surface: Wipe the steel insert and surrounding area with a solvent‑free cleaner to remove grease, dirt, and old sealant.
4. Apply anti‑seize compound (optional): Lightly coat the metal surfaces to aid future removal and prevent galling.
5. Insert the new bush: Align the left or right version with the mounting cavity. Press firmly until it seats fully into place.
6. Reassemble components: Reinstall any bolts, tie‑rods, or suspension links that were removed during disassembly.
7. Torque specifications: Tighten all fasteners to the manufacturer’s recommended torque values (typically 70–90 Nm for control arm bolts).
8. Test drive: Conduct a short test drive to confirm smooth operation and absence of rattles or clunking noises.

Performance Benefits

• Enhanced ride quality: The bush’s elastomeric properties dampen road irregularities, delivering a smoother passenger experience.
• Improved handling stability: By maintaining precise control arm geometry, the component contributes to consistent steering response and cornering performance.
• Reduced maintenance costs: Its long service life means fewer replacements compared to cheaper plastic alternatives.
• Noise reduction: The rubber interface absorbs vibrations that would otherwise transmit into the cabin, lowering NVH levels.

Maintenance & Inspection Tips

Although the bush is designed for durability, regular inspection can preempt potential issues:

• Check for visible cracks, bulges, or excessive wear during routine suspension inspections.
• Inspect surrounding bolts and fasteners for tightness; loose hardware can accelerate bush degradation.
• Avoid exposure to extreme temperatures (>120 °C) for prolonged periods, as this may soften the rubber core.
