Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, top off with the recommended power steering fluid type (consult owner's manual for specifications).
Replace the reservoir cap securely.

3. Inspect and Replace Damaged Components

Power Steering Pump:
- Remove the serpentine belt using a belt removal tool.
- Disconnect the power steering pump hoses using a wrench and drain any residual fluid into a container.
- Remove the pump from its mounting bracket (usually requires a socket set).
- Install the new power steering pump by reversing the removal process and reattach the hoses.
Steering Rack and Pinion:
- Lift the vehicle using a jack and secure with jack stands.
- Remove the tie rod ends by loosening the nuts and using a tie rod puller.
- Detach the steering rack from the subframe by removing the mounting bolts with a socket set.
- Disconnect the input shaft from the steering column.
- Replace with a new steering rack and reassemble by reversing the steps.

4. Reassemble and Refill

Once all repairs are made, reattach the serpentine belt.
Refill the power steering fluid reservoir to the appropriate level.
Start the engine and turn the steering wheel from lock to lock a few times to bleed air from the system.

5. Final Check

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay and the area is clean.
