Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and allow the vehicle to cool if driven recently.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check fluid level; replenish with the manufacturer-recommended power steering fluid if low.
3. If fluid is contaminated or burnt, drain the system and replace with fresh fluid.

3. Inspect and Replace CV Joints

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels for access to the CV joints.
3. Inspect the CV boots for tears; replace if damaged.
4. If the CV joint is damaged, remove the axle nut, detach the joint from the hub, and replace it with a new CV joint or axle as needed.

4. Check and Replace Wheel Bearings

Sub-steps:
1. While the wheel is off, spin the hub to listen for grinding noises.
2. If noise is present, remove the brake caliper and rotor to access the wheel bearing.
3. Remove the wheel bearing retaining nut and pull the bearing assembly out.
4. Replace with a new bearing and reassemble components.

5. Inspect and Replace Tie Rod Ends

Sub-steps:
1. Locate the tie rod ends connected to the steering rack and wheel assembly.
2. Check for any play or damage; if loose, mark the position for alignment purposes.
3. Use a tie rod end puller to remove the old tie rod end and replace with a new one.
4. Reattach and ensure alignment marks are correct.
