Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, brake cleaner, safety goggles, gloves
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel by loosening the lug nuts with a socket set and lifting the vehicle with a jack.
2. Remove the brake caliper by unbolting it and carefully hanging it to avoid straining the brake line.
3. Inspect the brake pads and rotors for wear; replace if pads are worn down to the indicator or rotors are scored.
4. Clean the brake components with brake cleaner before reassembly.
5. Reinstall the caliper and wheel, ensuring all bolts are torqued to manufacturer specifications.

3. Inspect Drivetrain Components

Sub-steps:
1. Visually inspect the axles for any signs of damage or excessive play.
2. Check the driveshaft for any signs of wear or looseness.
3. If any components are damaged, replace them with OEM or quality aftermarket parts, ensuring proper installation.

4. Check Wheel Bearings

Sub-steps:
1. Lift the vehicle and grab the wheel at the 12 and 6 o'clock positions.
2. Wiggle the wheel to check for any play; if present, the bearing may need replacement.
3. If necessary, disassemble the hub assembly and replace the wheel bearing, following manufacturer guidelines.
