Technical Specifications

Installation Overview

Installing the Bilstein 38‑236198 involves removing the existing coil spring and replacing it with the new unit. The process typically requires:

1. Removing wheel assembly and brake components to access the rear suspension.
2. Using a coil spring compressor or hydraulic press to safely compress the old spring.
3. Installing the new spring onto the axle shaft, ensuring proper alignment.
4. Reassembling all suspension components in reverse order of removal.

For optimal performance, it is recommended that the installation be performed by a qualified technician familiar with BMW suspension systems.
