Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely raise it with jack stands.
Disconnect the battery for safety if working near electrical components.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir and check the fluid level.
- If the fluid is low, add the recommended type (typically ATF or specific power steering fluid).
- If the fluid is dirty or contaminated, drain and replace it:
  - Remove the power steering reservoir cap.
  - Use a turkey baster or siphon to remove old fluid.
  - Refill with fresh fluid and check for leaks.

3. Inspect and Replace CV Joints

Sub-steps:
- Locate the CV joints and boots on both front axles.
- Check for any tears or leaks in the CV boots.
- If damaged, remove the axle nut (typically requires a socket and breaker bar).
- Disconnect the lower control arm and remove the axle from the hub.
- Replace the CV joint or axle assembly as needed.
- Reassemble in reverse order, ensuring the axle nut is torqued to manufacturer specifications (usually around 150 ft-lbs).

4. Inspect and Replace Wheel Bearings

Sub-steps:
- With the wheel removed, grasp the hub and check for any play indicating a worn bearing.
- If necessary, remove the brake rotor and access the wheel bearing.
- Use a bearing puller to remove the old bearing.
- Install the new wheel bearing, ensuring it is pressed in properly.
- Reassemble the rotor and wheel, torquing lug nuts to specifications (typically around 76 ft-lbs).

5. Inspect Suspension Components

Sub-steps:
- Visually inspect struts, control arms, and bushings for any signs of wear or damage.
- Replace any worn suspension components, following specific removal and installation instructions for each component.
- Recheck alignment settings after any suspension work.
