Solution

1. Preparation

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

2. Inspect and Replace Worn Suspension Components

Inspect Suspension:
- Visually examine control arms, bushings, and struts for any signs of wear or damage.
Replace Components:
- If any components are worn, remove the affected parts using a socket set.
- Install new parts, ensuring they are torqued to the manufacturer's specifications (consult service manual for specific torque values).

3. Check and Adjust Power Steering System

Inspect Power Steering Fluid:
- Check the fluid reservoir for proper levels; if low, top off with the recommended power steering fluid.
Bleed the System:
- If the fluid is contaminated, drain and refill, then bleed the system by turning the steering wheel lock-to-lock with the engine running.

4. Inspect and Replace CV Joints

Visual Inspection:
- Check CV joints and boots for cracks or tears.
Replace If Necessary:
- Remove the axle nut and disconnect the CV joint from the transmission.
- Replace the CV joint, ensuring proper alignment and securing with the correct torque.

5. Inspect Wheel Bearings

Check for Play:
- Remove the wheel and inspect the wheel bearings by rotating them by hand.
Replace If Necessary:
- If the bearings are rough or have excessive play, remove the hub assembly and replace the bearings, ensuring they are properly greased and seated.
