LEMFÖRDER 35386 01 Control Arm-/Trailing Arm Bush For BMW 5

Overview of the Component

The LEMFÖRDER 35386 01 is a high‑performance control arm bush, also known as a trailing arm bush, specifically engineered for the BMW 5 Series (F10/F11) from 2009 to 2016. This critical suspension element connects the vehicle’s front or rear axle to the chassis, providing precise articulation while absorbing road shocks and vibrations.

Key Functional Roles

• Load Distribution: The bush transmits longitudinal forces generated during acceleration, braking, and cornering from the axle to the frame.
• Vibration Dampening: Its elastomeric core reduces harsh road feel, ensuring a smooth ride for occupants.
• Alignment Stability: By maintaining correct camber and caster angles, it preserves tire contact patches and enhances handling performance.
• Durability Under Stress: Designed to endure repeated flexing without significant wear or loss of stiffness.

Material Composition

The bush is constructed from a proprietary blend of high‑grade polyurethane elastomer encased in a robust steel housing. This combination delivers:

• High Impact Resistance: Protects against sudden road impacts.
• Temperature Stability: Maintains performance across a wide climate range.
• Low Degradation Rate: Minimizes oil migration and wear over time.

Design Features

The 35386 01 incorporates several advanced design elements that set it apart from standard aftermarket options:

1. Symmetrical Geometry: Ensures identical performance on both left and right sides, simplifying installation.
2. Optimized Bore Size: Matches the OEM control arm dimensions for a snug fit without requiring additional adapters.
3. Pre‑Lubricated Seals: Reduces initial friction during assembly, allowing for smoother operation from day one.
4. Corrosion‑Resistant Finish: The steel housing is treated to resist rust and oxidation, extending service life.

Installation Guidelines

Proper installation is essential for achieving the intended performance benefits. Follow these steps for a reliable fit:

1. Preparation: Clean the control arm and mounting points to remove debris and old grease.
2. Alignment Check: Verify that the bush’s inner diameter matches the control arm’s outer diameter; any discrepancy may require a custom adapter.
3. Lubrication: Apply a thin layer of high‑temperature grease to the bush’s interior surfaces before insertion.
4. Insertion: Slide the bush onto the control arm, ensuring it sits flush against the mounting flange.
5. Tightening Sequence: Use a torque wrench to secure the mounting bolts in a crisscross pattern, following manufacturer specifications for torque values.
6. Final Inspection: Confirm that there is no play or misalignment; perform a quick spin test to ensure smooth rotation.

Compatibility and Fitment

The LEMFÖRDER 35386 01 is specifically tailored for the BMW 5 Series (F10/F11) models produced between 2009 and 2016. It fits both front and rear suspension configurations, including:

• Front Control Arms: Left and right sides.
• Rear Trailing Arms: Left and right sides.
• Other Vehicles: The design is also compatible with certain luxury models that share similar suspension geometry, such as select Rolls‑Royce and Alpina variants.

Performance Benefits

Choosing the 35386 01 bush delivers tangible improvements in driving dynamics:

• Enhanced Handling: Reduced camber loss during hard cornering leads to more predictable steering response.
• Improved Ride Comfort: The elastomeric core absorbs road irregularities, lowering cabin noise and vibration.
• Longer Service Life: High‑quality materials resist wear, reducing the need for frequent replacements.
• Consistent Tuning: Maintains suspension geometry over time, preserving the vehicle’s original tuning characteristics.

Maintenance Tips

While the bush is designed to be low‑maintenance, periodic checks can extend its lifespan:

1. Visual Inspection: Look for cracks, bulges, or oil leakage around the housing.
2. Lubrication Check: If you notice increased noise or stiffness, consider reapplying a suitable grease to the interior surfaces.
3. Replacement Interval: For most drivers, the bush should last well beyond typical mileage thresholds; however, if you drive aggressively or on rough terrain, inspect more frequently.
