Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level; if low, top off with the manufacturer-recommended power steering fluid.
3. If the fluid is contaminated, proceed to flush the system.
Tools Required:
- Funnel
- Rags for spills

3. Check and Replace Power Steering Pump (if necessary)

Sub-steps:
