To avoid damage to the steering rack while removing the tie rod, turn the steering until the end of the rack is as far as possible inside the rack housing. When reassembling, grease the tie rod taper to ensure that the rack boot support buffer or the small end of the rack boot slides on the tie rod when tightened, preventing the rack boot from twisting. Inspect the boot for any signs of damage and replace it if necessary, using new band clamps, which come with the new rack boot. The installation follows the reverse of removal, ensuring that threaded parts are clean, applying anti-seize paste on inner tie rod threads, using new self-locking nuts where applicable, and utilizing previously made reference marks to set the toe temporarily. After reassembling the steering, have the car professionally aligned and carry out the steering angle sensor adjustment using a BMW scan tool.
