LEMFÖRDER 36398 01 Control Arm-/Trailing Arm Bush For BMW X3

LEMFÖRDER 36398 01 Control Arm / Trailing Arm Bush – Precision for the BMW X3

The LEMFÖRDER 36398 01 Control Arm / Trailing Arm Bush is engineered to deliver superior performance and durability for the BMW X3 (F25) 2010‑2017. This component is a critical element of the rear suspension system, ensuring optimal handling, ride comfort, and longevity under varying driving conditions.

Key Features & Technical Specifications

• Material Composition: High‑strength, heat‑treated steel core surrounded by a robust polyurethane elastomer. This combination offers excellent load distribution and resistance to fatigue.
• Design: Dual‑sided mounting flange with integrated bushings for both left and right rear control arms, allowing symmetrical performance.
• Dimensions: Inner diameter of 47.4 mm, matching the OEM specifications for the BMW X3 series.
• Load Capacity: Rated for high torsional and axial loads typical of rear suspension systems in luxury SUVs.
• Installation: Tool‑free, with a clear alignment guide to ensure correct positioning during assembly.
• Compatibility: Designed for the rear inner control arm (also known as trailing arm) on both left and right sides of the vehicle.

Functional Role in the Suspension System

The control arm bush acts as a pivot point that allows the rear trailing arm to move smoothly while maintaining precise geometry. It absorbs shock, dampens vibrations, and prevents metal‑to‑metal contact that could lead to premature wear. By maintaining the correct camber and toe angles, it directly influences:

• Vehicle Stability during cornering and braking.
• Wheel Alignment, reducing uneven tire wear.
• Ride Comfort, by isolating road irregularities.

Benefits of Choosing LEMFÖRDER 36398 01

• Enhanced Durability: The polyurethane elastomer resists cracking and deformation even under high temperatures.
• Consistent Performance: Maintains low friction coefficients, ensuring reliable handling over the component’s lifespan.
• Easy Replacement: The design allows for quick removal and installation without specialized tools.
• OEM‑Approved: Meets or exceeds BMW’s original equipment specifications, guaranteeing compatibility and safety.

Installation Guide Overview

1. Preparation: Clean the mounting surfaces and remove any debris or old bushings.
2. Alignment: Position the new bush between the control arm and the rear axle housing, ensuring the inner diameter aligns with the mounting flange.
3. Securing: Tighten the mounting bolts to the manufacturer’s torque specification, typically around 30 Nm for this component.
4. Verification: Check the alignment and ensure there is no play or binding in the control arm movement.

Maintenance Tips

• Inspect the bush periodically for signs of wear, such as visible cracks or excessive play.
• Keep the surrounding area clean to prevent contamination of the elastomer surface.
• Avoid excessive force or impact that could damage the bush during driving or loading.

Why LEMFÖRDER Stands Out in the Market

LEMFÖRDER is renowned for its commitment to quality and precision engineering. The 36398 01 model exemplifies this reputation through:

• Rigorous Testing: Each batch undergoes load and fatigue tests to ensure reliability.
• Material Traceability: Source materials are tracked to guarantee consistency.
• Customer Support: Technical assistance is available for installation queries and performance optimization.

Applications Beyond the BMW X3

While specifically designed for the BMW X3 (F25) 2010‑2017, the LEMFÖRDER 36398 01 control arm bush is also compatible with a range of other vehicles that share similar suspension geometry. Its universal design allows it to serve as an effective replacement in various rear axle configurations.

Conclusion

The LEMFÖRDER 36398 01 Control Arm / Trailing Arm Bush delivers unmatched performance, durability, and ease of installation for the BMW X3. Its precise engineering ensures that drivers experience consistent handling, reduced tire wear, and a smoother ride, making it an essential component for maintaining the vehicle’s high standards of quality and safety.
