LEMFÖRDER 37720 01 Control Arm-/Trailing Arm Bush For Volkswagen Golf VII

Overview of the Component

The LEMFOERDER 37720 01 is a high‑performance control arm bush, also known as a wishbone bush or trailing arm mounting. It serves as the critical interface between the vehicle’s front suspension geometry and the chassis, providing both structural support and vibration isolation. Designed for a wide range of Volkswagen Group vehicles—including the Golf VII, Audi A3, Seat Leon, Skoda Octavia, and others—this bush delivers reliable handling, durability, and consistent ride quality.

Key Functional Roles

• Load Transfer: The bush transmits vertical loads from the wheel assembly to the vehicle frame while maintaining precise alignment of the control arm.
• Vibration Dampening: Its rubber‑metal construction absorbs road shocks, reducing noise and improving passenger comfort.
• Alignment Stability: By resisting lateral forces, it preserves camber, caster, and toe settings over time, which is essential for tire wear and steering response.

Material Composition

The component features a dual‑layer construction: an inner rubber core encapsulated by a metal sleeve. The rubber core offers elasticity and shock absorption, while the metal sleeve provides structural rigidity and protects against wear. This combination ensures long service life even under harsh driving conditions.

Compatibility and Fitment

The bush is engineered to fit the following vehicle models:

• Volkswagen Golf VII (5G1, BQ1, BE1, BE2)
• Audi A3, Audi TT, Seat Leon, Skoda Octavia
• Other VW Group front‑axle vehicles that use the same wishbone geometry.

It is available in both left and right side variants to accommodate symmetrical suspension setups. The part number 37720 01 ensures exact match with OEM specifications, guaranteeing seamless installation without modification.

Installation Highlights

• Tool Requirements: Standard socket set, torque wrench, and a small pry bar for removal of the old bush if necessary.
• Tightening Sequence: Follow manufacturer torque specifications to avoid over‑tightening or under‑tightening, which can compromise suspension geometry.
• Alignment Check: After installation, verify camber and caster angles with a precision alignment tool to ensure optimal handling.

Performance Benefits

• Improved Handling: The bush’s precise geometry maintains suspension kinematics, leading to tighter steering response.
• Reduced Noise & Vibration: Rubber core dampens road irregularities, resulting in a quieter cabin and smoother ride.
• Extended Lifespan: High‑grade materials resist cracking and wear, reducing the need for frequent replacements.

Maintenance Tips

Although the bush is designed to be low‑maintenance, regular inspection can preempt potential issues:

• Check for visible signs of rubber degradation such as cracks or hardening.
• Inspect metal sleeve for corrosion or excessive wear.
• Replace the bush if any deformation is observed to maintain safety and performance.
