Solution

1. Preparation

• Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent any electrical issues.
• Gather necessary tools and replacement parts.

2. Inspect and Replace Drive Belts

• Tools Required: Socket set, belt tensioner tool, flashlight
• Check the condition of the serpentine belt and any accessory belts for wear or damage.
• If worn, use a belt tensioner tool to relieve tension and remove the belt.
• Replace with a new belt, ensuring proper alignment and tension according to manufacturer specifications.

3. Transmission Fluid Service

• Tools Required: Transmission fluid pump, socket set, torque wrench
• Locate the transmission fluid dipstick or fill plug and remove.
• Check fluid level and condition; if low, top off with the manufacturer-recommended transmission fluid.
• If dirty or burnt, drain the transmission fluid using the pan drain plug, and replace with new fluid.
• Reinstall the pan (if removed) and ensure it is torqued to specifications.

4. Inspect Wheel Bearings and Differential

• Tools Required: Jack and jack stands, wheel chocks, socket set
• Raise the vehicle and remove the wheels.
• Inspect wheel bearings for play or noise; replace if necessary.
• Check the differential for leaks or unusual noises during inspection. If damaged, it may require replacement or servicing.
