Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level; top off with the manufacturer-recommended fluid if low.
3. Inspect the fluid for contamination; if dirty, consider a fluid flush.
Tools Required: Funnel, power steering fluid.
Safety Warnings: Ensure engine is off and cool before checking fluid.

3. Inspect Steering Components

Sub-steps:
1. Visually check the steering rack and linkage for any signs of damage or wear.
2. Wiggle the steering wheel to check for excessive play in the steering components.
3. If any worn parts are found, remove and replace as necessary.
Tools Required: Socket set, wrenches.

4. Tire Inspection

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate to the recommended PSI.
2. Inspect tires for uneven wear patterns; rotate or replace tires if necessary.
Tools Required: Tire pressure gauge, tire inflator, jack and jack stands.

5. Test Electric Power Steering System

Sub-steps:
1. Reconnect the battery terminal.
2. Start the vehicle and turn the steering wheel from lock to lock to assess responsiveness.
3. If issues persist, test the EPS motor and control module with a multimeter for proper voltage and resistance.
Tools Required: Multimeter.
