Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface, turn off the engine, and engage the parking brake.
Disconnect the battery if necessary to ensure safety while working on electrical components.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, pry bar, jack, jack stands.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel to access the suspension components.
3. Inspect control arms and bushings for cracks or excessive wear. Replace if necessary.
4. Check struts for leakage or damage. Replace if needed.
5. Reassemble the suspension components and torque all bolts to manufacturer specifications (refer to the service manual for specific torque values).

3. Inspect and Replace CV Joints

Tools Required: Socket set, CV joint puller (if necessary).
Sub-steps:
1. Remove the front wheel and inspect the CV joint boots for tears or grease leakage.
2. If damage is found, remove the axle nut and disconnect the CV joint from the hub.
3. Replace the CV joint or axle assembly as required.
4. Reinstall the CV joint and wheel, torque the axle nut to manufacturer specifications.

4. Inspect and Replace Wheel Bearings

Tools Required: Socket set, bearing puller, grease.
Sub-steps:
1. Remove the wheel and brake components to access the wheel bearing.
2. Check for play in the wheel bearing by wiggling the tire.
3. If the bearing is worn, use a bearing puller to remove it.
4. Install a new bearing and pack it with grease as per manufacturer recommendations.
5. Reassemble the brake components and wheel, ensuring all bolts are torqued properly.
