Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery (if working on electrical components).

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, serpentine belt tool.
Sub-steps:
1. Locate the serpentine belt tensioner.
2. Use the serpentine belt tool to relieve tension on the belt.
3. Remove the old belt and check for any signs of wear or damage.
4. Install the new serpentine belt, ensuring it follows the correct routing diagram.
5. Reapply tension and check for proper alignment.

3. Transmission Fluid Inspection

Tools Required: Transmission fluid dipstick, funnel.
Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean and reinsert it to check fluid level and condition.
3. If the fluid is low, add the manufacturer-recommended transmission fluid.
4. If the fluid is discolored or has a burnt smell, consider a transmission fluid change or flush.

4. Wheel Bearing Inspection

Tools Required: Jack, jack stands, wheel chocks, socket set.
Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Remove the wheel and inspect the wheel bearing for play or noise.
3. Spin the hub and listen for any grinding or roughness.
4. If defective, replace the wheel bearing following manufacturer specifications.
