Remove the bolts securing the steering rack to the subframe and carefully extract the rack from the vehicle.
Inspect the old steering rack for damage or leaks.
Install the new steering rack by reversing the removal steps and ensuring all bolts are torqued to manufacturer specifications.

4. Reconnect Components

Reattach the tie rods and adjust them as necessary.
