Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Jack and jack stands, socket set, torque wrench, screwdriver set, pry bar.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir and check the fluid level.
If low, refill with the manufacturer's recommended fluid.
If fluid is dirty or contaminated, drain and replace it.
Sub-steps:
1. Remove the cap from the power steering reservoir.
2. Use a siphon pump to remove old fluid.
3. Refill with fresh power steering fluid.
4. Start the engine and turn the steering wheel to circulate the fluid.

3. Inspect and Replace CV Joints

Raise the front of the vehicle and secure it with jack stands.
Inspect the CV joints and boots for any cracks or leaks.
If damaged, replace the CV joint assembly.
Sub-steps:
1. Remove the wheel and tire assembly.
2. Disconnect the lower control arm from the steering knuckle.
3. Remove the axle nut and slide the axle out of the hub.
4. Install the new CV joint and reassemble in reverse order.

4. Check and Replace Wheel Bearings

With the vehicle still raised, check for play in the wheel bearings by rocking the wheel.
If there is excessive play, replace the wheel bearings.
Sub-steps:
1. Remove the wheel and brake caliper.
2. Remove the rotor and hub assembly.
3. Replace the bearing using a bearing puller if necessary.
4. Reassemble everything with proper torque specifications.
