Solution

1. Preparation

Gather tools: Socket set, torque wrench, jack stands, and safety glasses.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir.
- Check the fluid level; if low, top off with the recommended type (usually ATF or specific steering fluid).
- If the fluid is dirty or burnt, drain and replace it.
Tools Required: Funnel, fluid container for disposal.

3. Inspect Steering Components

Sub-steps:
- Jack up the front of the vehicle and secure with jack stands.
- Visually inspect tie rods and ball joints for damage or excessive wear.
- If any components are damaged, remove and replace them, ensuring to torque new parts to manufacturer specifications.
Torque Values: Refer to the service manual for specific torque specifications for tie rods and ball joints.

4. Examine Suspension Components

Sub-steps:
- Check shock absorbers and struts for leaks or play by pushing down on the vehicle and observing rebound.
- Inspect control arms for any cracks or bushings that may need replacement.
Tools Required: Wrench set, pry bar (if needed).

5. Inspect CV Joints and Axles

Sub-steps:
- Check CV boots for tears or leaks; replace if necessary.
- If CV joints are suspected, replace them by removing the axle from the hub and differential.
Tools Required: Axle puller, socket set.
