3. Inspect and Replace Seals

Step 1: Clean the steering rack thoroughly to remove dirt and debris.
Step 2: Remove the old seals using a seal puller or flathead screwdriver carefully to avoid damaging the housing.
Step 3: Install new seals by lubricating them with power steering fluid and pressing them into place evenly.
Step 4: Reassemble the steering rack, ensuring that all components are tight and secure.

4. Reinstall the Steering Rack

Step 1: Slide the steering rack back into position, aligning it with the subframe.
Step 2: Secure the steering rack with the appropriate bolts and torque them to manufacturer specifications (consult service manual for exact torque values).
Step 3: Reconnect the steering shaft and ensure the pinch bolt is tightened to specification.
Step 4: Reattach the tie rod ends to the steering knuckles and torque bolts properly.

5. Refill and Bleed the Power Steering System

Step 1: Fill the power steering reservoir with the correct type of power steering fluid.
