Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Tires (if necessary)

Remove the affected tire(s) using a socket set.
Inspect for uneven wear or damage.
If necessary, replace the tire with a new one, ensuring proper alignment and balance.

3. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the recommended levels.
If low, refill with the appropriate type of power steering fluid specified in the owner's manual.

4. Replace Worn Steering Components

If the inspection shows wear on tie rods or the steering rack:
1. Use a socket set to remove the tie rod end or steering rack.
2. Install the new component and torque to manufacturer specifications (usually 35-45 ft-lbs).
3. Reconnect any electrical connections and ensure all parts are secure.

5. Inspect and Replace Suspension Components

If suspension components are worn:
1. Remove the affected control arm using a socket set.
2. Inspect bushings and joints for wear.
3. Replace with new components, using a torque wrench to secure all fasteners to manufacturer specifications.
