Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, OBD-II scanner, flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean and reinsert to check fluid level.
3. If the fluid is low, add the recommended transmission fluid (refer to owner's manual for specifications).
4. If the fluid appears dark or has a burnt smell, drain and replace the fluid and filter.
5. Recheck the fluid level after replacement.

3. Inspect and Replace Drive Belts

Sub-steps:
1. Visually inspect the drive belts for cracks, fraying, or excessive wear.
2. Check the tension of the belts; they should be tight but not overly so.
3. If any issues are identified, use a socket set to remove the old belts.
4. Install new belts according to the manufacturer's specifications, ensuring proper routing.
5. Reconnect the battery terminal.

4. Wheel Bearing Inspection and Replacement (if necessary)

Sub-steps:
1. Safely lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel to gain access to the hub assembly.
3. Check for play in the wheel bearing by moving the wheel up and down or side to side.
4. If play is detected, remove the bearing assembly using appropriate tools.
5. Replace with a new bearing and reassemble.
