This control arm is built to exact specifications to ensure a seamless fit on the rear axle, providing improved vehicle stability and vibration dampening.

Extended Product Information

FAQs

Is this part compatible with my specific BMW?

The Febi 39086 is designed for specific BMW 5-Series models. Always check your VIN or cross-reference your current MPN against this component to ensure a perfect match.

Can I install this myself without professional help?

While experienced DIYers may install the physical component, professional calibration of driver assistance systems is required for safety.

Does this kit include mounting bolts?

The product information covers the arm itself. It is standard industry practice to replace mounting hardware with new bolts when installing new suspension arms.

How often should I replace my suspension arms?

Suspension arms do not have a set schedule, but they should be inspected for rubber degradation every 50,000 miles or if you experience handling degradation.

Does this part need to be greased?

No, this component comes ready for installation and features sealed maintenance-free bushings.

Troubleshooting

Persistent vibration or noise after installation

Verify that all mounting hardware is torqued to the correct specifications and check for any misalignments in the rear subframe.

Driver assistance system warning light

This is expected if the vehicle has ADAS; schedule a professional calibration service to recalibrate the sensors to the new alignment settings.

Suspension feels loose or handles poorly

Check that the bushing bolts were tightened while the suspension was under load (ride height) rather than with the wheel hanging freely.

Pros and Cons

Pros

  • Matches OEM specifications exactly
  • Restores original handling dynamics
  • Durable construction for long-term reliability
  • Direct fit for specific BMW 5-Series rear axle assemblies

Cons

  • Requires professional installation for sensor calibration
  • Not suitable for modified or non-standard suspension setups
  • Limited to specific BMW 5-Series model years
  • Requires specialized tools for rear axle bolt removal

Setup, Compatibility & Care

Installation of the Febi 39086 must be performed according to the vehicle manufacturer’s service manual, specifically adhering to torque specifications for the rear axle assembly. Ensure the vehicle is properly lifted using a professional-grade automotive lift.

  1. Secure the vehicle and remove the rear wheel.
  2. Detach the worn suspension arm, taking care not to damage adjacent components.
  3. Align the new arm into the 12 mm and 14 mm mounting points.
  4. Torque all hardware to manufacturer-recommended settings.

Crucially, if your BMW is equipped with driver assistance systems (such as lane keeping or active cruise control), you must perform a sensor calibration post-installation. Regular inspection during oil changes is recommended to check for torn rubber bushings or excessive corrosion on the arm body.
