Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, OBD-II scanner, flashlight, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Components

Remove the wheel using a lug wrench.
Inspect brake pads for thickness; replace if worn down to 3mm or less.
Check rotors for scoring or grooving; replace if damaged.
Sub-steps:
- If replacing pads, compress the caliper piston using a brake tool.
- Install new brake pads and reassemble the caliper.
- Torque bolts to manufacturer's specifications (generally 79-95 ft-lbs for caliper bolts).

3. Check Wheel Bearings

Remove the wheel hub and brake assembly.
Inspect the wheel bearings for any signs of roughness or play.
Sub-steps:
- If bearings are worn, replace them using a bearing puller.
- Lubricate new bearings with high-temperature wheel bearing grease before installation.
- Reassemble and torque the hub nut to manufacturer's specifications.

4. Inspect Driveshaft and CV Joints

Lift the vehicle and support it securely.
Inspect the driveshaft for any signs of damage or play.
Check CV joints for torn boots or excess wear.
Sub-steps:
- If a CV joint is damaged, remove the axle from the hub and replace the CV joint or entire axle assembly.
- Ensure proper alignment during reinstallation.
