Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Wheel Bearings

Tools Required: Jack and jack stands, socket set, torque wrench, wheel bearing puller.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the hub assembly.
3. Check the wheel bearing for any play by attempting to rock the wheel back and forth.
4. If the bearing is faulty, remove the hub assembly and use a bearing puller to extract the old bearing.
5. Install the new bearing, ensuring it is seated properly, and reassemble the hub.

3. Inspect and Repair Drivetrain Components

Tools Required: Socket set, torque wrench, CV joint tool (if needed).
Sub-steps:
1. Inspect the driveshaft and CV joints for any signs of wear or damage.
2. If CV joints are worn, remove the axle from the transmission and replace the joint or the entire axle if necessary.
3. Reinstall the axle and torque the bolts to the manufacturer specifications.

4. Check Engine and Transmission Mounts

Tools Required: Socket set.
Sub-steps:
1. Visually inspect the engine and transmission mounts for cracks or excessive wear.
2. If mounts are damaged, remove the old mounts and replace them with new ones.
3. Torque the mounting bolts to the specified values.
