Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Belts

Tools Required: Socket set, belt tensioner tool
Steps:
1. Open the hood and locate the serpentine belt.
2. Inspect the belt for signs of wear, such as cracks or fraying.
3. If the belt is damaged, use a belt tensioner tool to relieve tension and remove the old belt.
4. Install a new serpentine belt by routing it according to the belt diagram.
5. Ensure the belt is properly tensioned and aligned.

3. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel
Steps:
1. Locate the transmission dipstick and pull it out to check the fluid level.
2. If low, add the correct type of transmission fluid (refer to owner's manual).
3. If the fluid is discolored or has a burnt smell, consider a fluid change.
4. Drain the old fluid using a transmission fluid pump and replace it with fresh fluid.

4. Inspect and Replace Wheel Bearings or CV Joints (if necessary)

Tools Required: Jack and jack stands, socket set, pry bar
Steps:
1. Raise the front of the vehicle and secure it on jack stands.
2. Remove the wheel to access the wheel hub and CV joint.
3. Inspect the wheel bearing for play by grabbing the tire at 12 and 6 o'clock and shaking it.
4. If a wheel bearing is faulty, remove the hub assembly and replace the bearing.
5. If CV joints are worn, remove the axle and replace the affected joint.
