Tools Required: Socket set, torque wrench, fluid catch pan.
Remove any brackets or covers obstructing access to the power steering pump.
Disconnect the power steering lines from the pump (be ready to catch any leaking fluid).
Unbolt the pump from its mounting location and remove it.
Install the new power steering pump, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the power steering lines and check for leaks.

4. Inspect and Replace Steering Rack (if damaged)

Tools Required: Socket set, steering wheel puller, tie rod end puller.
Remove the front wheels for better access.
Disconnect the tie rods from the steering rack.
Unbolt the steering rack from its mounts and detach any connecting components (e.g., intermediate shaft).
Install the new steering rack, ensuring all connections are properly tightened.
Reconnect the tie rods and check for proper alignment.

5. Alignment Check

After repairs, perform a wheel alignment to ensure proper steering response and tire wear.
