Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and multimeter.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using the lug wrench.
2. Inspect brake pads and rotors for wear; replace if pads are less than 3mm thick or rotors are scored.
3. Clean the brake components with brake cleaner.
4. Reassemble with new brake pads and rotors, ensuring to torque the lug nuts to manufacturer specifications (typically around 76 ft-lbs).

3. Check and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel and brake assembly.
2. Inspect the wheel bearing for signs of wear or damage; if grinding or excessive play is observed, replace the bearing.
3. To replace, remove the bearing hub using a socket set and install a new bearing, torquing to specifications.
4. Reassemble the brake assembly and wheel.

4. Inspect and Repair Drivetrain Components

Sub-steps:
1. Inspect the CV joints for any tears or leaks in the boot; if damaged, replace the CV axle.
2. Check the driveshaft for any signs of damage or wear.
3. Replace any damaged components and ensure all bolts are torqued to specifications.
