Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Drive Belts

Tools Required: Socket set, belt tensioner tool, torque wrench.
Sub-steps:
1. Remove the engine cover if necessary.
2. Use a belt tensioner tool to relieve tension on the drive belt.
3. Carefully remove the old belt from the pulleys.
4. Inspect pulleys for wear or damage; replace if necessary.
5. Install the new drive belt, ensuring it is properly seated in all grooves.
6. Reapply tension using the belt tensioner tool and check the alignment.

3. Inspect and Replace Transmission Fluid

Tools Required: Transmission fluid pump, fluid catch pan, funnel.
Sub-steps:
1. Locate the transmission fluid dipstick and check the fluid level.
2. If low, remove the transmission drain plug and drain old fluid into the catch pan.
3. Replace the transmission filter if applicable.
4. Use the fluid pump to add new transmission fluid through the dipstick tube.
5. Check the fluid level again with the engine running and adjust as necessary.

4. Check Differential Components

Tools Required: Socket set, torque wrench, differential fluid.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the differential cover and inspect for metal shavings or wear.
3. Replace worn gears or bearings as necessary.
4. Clean the differential housing and install a new gasket.
5. Refill the differential with the specified fluid type.
