Solution

1. Preparation

Gather tools and parts necessary for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint removal tool.
Steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel on the affected side.
3. Inspect the CV boot for tears or leaks; if damaged, replace the CV joint.
4. Remove the axle nut and the bolts securing the CV joint to the hub.
5. Use the CV joint removal tool to detach the CV joint from the axle.
6. Install the new CV joint, ensuring the boot is properly seated.
7. Reassemble by tightening the axle nut to the manufacturer’s torque specifications.

3. Inspect Power Steering System

Tools Required: Power steering fluid, funnel, OBD-II scanner (if necessary).
Steps:
1. Check the power steering fluid level and top up if low.
2. Inspect for leaks in the power steering system, including hoses and the pump.
3. If the fluid is dark or contains debris, flush the power steering system and refill with the recommended fluid.
4. Test the steering operation after the fluid change to ensure noise is resolved.

4. Check and Replace Wheel Bearings

Tools Required: Socket set, torque wrench, bearing puller.
Steps:
1. After removing the wheel, inspect the wheel bearing for play by shaking the wheel.
2. If play is detected, remove the brake caliper and rotor to access the bearing.
3. Use a bearing puller to remove the old bearing from the hub.
4. Install the new bearing and reassemble the brake components.
5. Torque all bolts to the manufacturer’s specifications.

5. Inspect Suspension Components

Tools Required: Socket set, pry bar.
Steps:
1. Inspect the control arms and bushings for any signs of wear or damage.
2. Replace any worn or damaged components as necessary.
3. Ensure all bolts are tightened to manufacturer specifications after replacement.
