Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Steering Components

Inspect Steering Rack and Linkage:
- Remove any protective covers if necessary.
- Check for play in the steering rack by moving the steering wheel back and forth.
Replace Worn Components:
- If any component (tie rod ends, steering rack, or linkage) shows excessive wear, proceed to replace it.
  - Use a socket set and wrenches to remove the old component.
  - Install the new component, ensuring to tighten to manufacturer specifications (consult repair manual for torque values).

3. Check and Adjust Suspension Components

Inspect and Replace Tie Rods:
- If tie rods are worn, remove the old tie rod ends.
- Install new tie rod ends, adjusting to ensure proper alignment.
Align the Wheels:
- After replacing any suspension components, perform a wheel alignment to ensure the steering geometry is correct.

4. Refill Power Steering Fluid

Check Fluid Level:
- Inspect the power steering fluid reservoir; if low, add the recommended type of fluid (consult the owner's manual for specifics).
Bleed the System if Necessary:
- If air is suspected, bleed the power steering system by turning the steering wheel from lock to lock several times with the vehicle running.
