4. Refill with manufacturer-recommended power steering fluid.
Tools Required: Siphon pump, fluid container.

3. Replace Worn Wheel Bearings

Sub-steps:
1. Raise the vehicle and securely support it with jack stands.
2. Remove the wheel to access the hub assembly.
3. Use a socket set to remove the hub assembly from the vehicle.
4. Inspect the bearing for wear; replace if necessary.
5. Install the new bearing and reassemble the hub assembly.
6. Torque the hub assembly bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench, bearing puller.

4. Check and Service the Drivetrain Components

Sub-steps:
1. Inspect the axles and CV joints for any signs of damage or wear.
2. If any components are damaged, remove and replace them.
3. Check the differential fluid level and condition; replace if contaminated.
4. Reassemble all components and ensure proper alignment.
Tools Required: Socket set, differential fluid, torque wrench.
