Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool.
Sub-steps:
1. Use the belt tensioner tool to relieve tension on the serpentine belt.
2. Remove the serpentine belt from the pulleys.
3. Inspect the belt for signs of wear or damage (cracks, fraying).
4. If damaged, replace with a new serpentine belt, ensuring proper routing.
5. Reapply tension and check for proper fitment.

3. Inspect and Replace Wheel Bearings (if applicable)

Tools Required: Jack, jack stands, socket set, torque wrench.
Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel to access the brake assembly and hub.
3. Inspect the wheel bearing for play by moving the wheel side to side.
4. If bearing is worn, remove the hub assembly and replace the wheel bearing.
5. Reassemble the hub, wheel, and torque bolts to manufacturer's specifications.

4. Transmission Fluid Inspection and Change (if needed)

Tools Required: Transmission fluid pump, fluid catching pan, socket set.
Sub-steps:
1. Locate the transmission fluid dipstick or drain plug.
2. Check fluid level and condition (color, smell).
3. If fluid is low or burnt, drain the fluid using a pump and replace with manufacturer-specified fluid.
4. Recheck the fluid level after filling.
