Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, torque wrench, belt tensioner tool
Sub-steps:
1. Locate the serpentine belt and tensioner assembly.
2. Use the tensioner tool to relieve tension on the belt.
3. Remove the old belt from the pulleys.
4. Inspect pulleys for damage or misalignment.
5. Install the new serpentine belt following the routing diagram.
6. Reapply tension using the tensioner tool and verify proper installation.

3. Check Transmission Fluid

Tools Required: Transmission fluid dipstick or funnel
Sub-steps:
1. With the engine warm, place the vehicle in park and open the hood.
2. Remove the transmission fluid dipstick and wipe it clean.
3. Reinsert the dipstick and remove it again to check the fluid level.
4. If low, add the appropriate type of transmission fluid until it reaches the proper level.
5. Inspect fluid for contamination; if dirty, consider a transmission fluid change.

4. Inspect Wheel Bearings and CV Joints

Tools Required: Jack, jack stands, pry bar
Sub-steps:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Remove the front wheels to access the wheel bearings and CV joints.
3. Check for play in the wheel bearings by rocking the wheel.
4. Inspect CV joints for any signs of grease leakage or torn boots.
5. Replace any worn components as necessary.
