Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues while working.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, jack stands, pry bar
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels for better access to suspension components.
3. Visually inspect the control arms and bushings for cracks or excessive wear.
4. If damaged, unbolt the control arm using the socket set, and replace with new parts.
5. Torque the new control arm bolts to the manufacturer's specifications.

3. Inspect and Replace CV Joints

Tools Required: Socket set, CV joint puller, torque wrench
Sub-steps:
1. Remove the axle hub nut using the socket set.
2. Disconnect the CV joint from the transmission and lower control arm.
3. Inspect the CV boot for tears; if damaged, replace the entire CV axle.
4. Install the new CV joint, ensuring it is properly seated, and torque the axle nut to manufacturer specifications.

4. Inspect Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench
Sub-steps:
1. With the front wheel removed, check for play in the wheel bearings by grabbing the wheel at 12 and 6 o'clock positions.
2. If there is excessive play, remove the wheel hub assembly.
3. Replace the bearings using a bearing puller and install new bearings.
4. Reassemble the hub and torque all bolts to specifications.
