Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to ensure safety.
Allow the vehicle to cool if the engine was recently running.

2. Inspect and Adjust Steering Components

Inspect Tie Rod Ends:
- Raise the front of the vehicle and secure it on jack stands.
- Use a socket set to remove the cotter pins and nuts securing the tie rods.
- Check for any excessive play or wear; if damaged, replace.
Check Steering Rack:
- Look for any leaks or damages in the steering rack.
- If the rack is damaged, proceed with removal:
  - Disconnect any hoses and electrical connections.
  - Remove bolts securing the rack to the subframe.
  - Carefully slide the rack out of its mounting position.

3. Replace Power Steering Fluid

Use a turkey baster to remove old power steering fluid from the reservoir.
Refill with manufacturer-recommended power steering fluid.
Turn the steering wheel from lock to lock to purge air from the system.

4. Align Steering Wheel

If the steering wheel is misaligned, it may need adjustment:
- Use an alignment tool to check the steering angle.
- Adjust the tie rods evenly until the steering wheel is centered when driving straight.

5. Final Assembly

Reinstall any components that were removed.
Reconnect the battery and ensure all electrical connections are secure.
Test the steering system for proper function.
