Sub-steps:
1. Lift the vehicle with a jack and secure it on jack stands.
2. Remove the wheel and brake caliper to access the hub assembly.
3. Spin the hub to check for noise or roughness. If present, proceed with replacement.
4. Remove the hub assembly using a socket set, noting the orientation.
5. Install a new hub assembly, torquing bolts to manufacturer specifications.
6. Reassemble the brake caliper and wheel.

4. Differential and Drivetrain Inspection

Sub-steps:
1. Check the differential fluid level and condition; replace if contaminated.
2. Inspect the driveshaft for play and signs of wear.
3. Replace any worn components as necessary, ensuring proper installation and torque specifications.
