Solution

1. Preparation

Gather tools and set the vehicle on a flat surface.
Ensure the engine is off and the vehicle is in park with the parking brake engaged.
Tools required: Jack, jack stands, socket set, torque wrench, and a screwdriver.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level and condition.
3. If low, add manufacturer-recommended power steering fluid until it reaches the proper level.
4. If the fluid is dark or contaminated, perform a fluid flush and replace with new fluid.

3. Inspect and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the axle assembly.
3. Inspect the CV joint for cracks or torn boots.
4. If damaged, remove the axle nut and disconnect the CV joint from the transmission.
5. Install a new CV joint or axle assembly, ensuring proper torque specifications are followed.

4. Check and Replace Steering Components

Sub-steps:
1. With the vehicle still lifted, inspect tie rods and ball joints for play or damage.
2. If any components are worn, remove the old part using a socket set.
3. Install new parts, ensuring that all nuts and bolts are torqued to manufacturer specifications.

5. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the brake caliper and rotor to access the wheel bearing.
2. Check for any roughness or play by rotating the hub.
3. If faulty, remove the wheel bearing using a bearing puller.
4. Install a new wheel bearing and reassemble the components.
