Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Brake System Inspection

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner.
Remove the wheel by loosening the lug nuts with a lug wrench.
Inspect the brake pads for thickness and wear; replace if below specifications.
Check the brake rotors for scoring or warping; replace if necessary.
Clean the brake components with brake cleaner before reassembly.
Reinstall the wheel and torque the lug nuts to manufacturer specifications.

3. Wheel Bearing and Driveshaft Inspection

Tools Required: Jack, jack stands, wheel chocks, torque wrench.
Lift the vehicle and remove the wheel to access the hub assembly.
Grasp the wheel at 12 and 6 o'clock positions and wiggle; any play indicates a bad wheel bearing.
If bearing replacement is needed, remove the hub assembly and replace the bearing.
Inspect the driveshaft for any signs of wear or play at the U-joints; replace if damaged.

4. Transmission Fluid Check

Tools Required: Transmission fluid dipstick (if applicable), funnel, transmission fluid (specific to vehicle).
Locate the transmission dipstick and check the fluid level; add fluid if low.
Inspect fluid for discoloration or burnt smell; replace if deteriorated.
If the fluid is contaminated, consider a complete fluid change and filter replacement.
