Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical systems.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Check fluid level and color; if dark or dirty, replace it.
3. Use a fluid pump to remove old fluid from the reservoir.
4. Refill with the recommended power steering fluid (consult the owner's manual for specifications).

3. Inspect and Replace CV Joints

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the front wheels for better access to the CV joints.
3. Check the CV boots for tears and inspect the joints for grinding or play.
4. If damaged, remove the axle nut and disconnect the CV joint from the hub.
5. Replace with a new CV joint assembly if necessary, ensuring proper torque specifications for the axle nut.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. With the vehicle still lifted, grasp the wheel at 12 and 6 o'clock positions and check for play.
2. If play is detected, remove the wheel and brake caliper to access the hub.
3. Remove the hub assembly and inspect the bearings for wear.
4. Replace the wheel bearings if they are worn or damaged, ensuring they are properly greased and torqued.

5. Check Suspension Components

Sub-steps:
1. Inspect the control arms, ball joints, and bushings visually for cracks or excessive wear.
2. If damaged, remove and replace the affected components.
3. Ensure all bolts are torqued to manufacturer's specifications.
