Solution

1. Preparation

Gather tools: jack and jack stands, tire iron, OBD-II scanner, multimeter, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if necessary.
2. Inspect tires for any visible damage, such as cuts, bulges, or uneven wear patterns.
3. Measure tread depth using a tread gauge; replace if worn below 2/32 inch.
Tools required: Tire depth gauge, visual inspection tools.

3. Wheel Bearing Check

Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure it with jack stands.
2. Grab the wheel at 12 and 6 o'clock positions and wiggle; listen for play or noise.
3. Spin the wheel and listen for grinding or roughness.
4. If defective, remove the wheel and proceed to replace the bearing.
Tools required: Socket set, bearing puller.

4. Drive Belt and Pulley Inspection

Sub-steps:
1. Remove the engine cover if applicable.
2. Inspect the drive belt for signs of wear, fraying, or cracks.
3. Check pulleys for alignment and smooth operation.
4. Replace the belt if it shows damage; ensure proper tension upon installation.
Tools required: Socket set, belt tension gauge.

5. Transmission Fluid Inspection

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick, wipe it clean, and reinsert to check fluid level.
3. Inspect fluid color and smell; it should be bright red and free of burnt odor.
4. If low or contaminated, perform a transmission fluid change.
Tools required: Transmission fluid, funnel, fluid pump.
