Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Drive Belts

Tools Required: Socket set, belt tensioner tool, flashlight.
Check the condition of the serpentine belt for cracks or wear.
If damaged, remove the belt by releasing tension using the tensioner tool.
Install a new belt by routing it according to the belt diagram found on the engine bay.
Reconnect the battery.

3. Transmission Fluid Service

Tools Required: Socket set, transmission fluid pump, drain pan.
Check the transmission fluid level. If low, add the manufacturer-recommended fluid.
If the fluid is dark or has a burnt smell, perform a transmission fluid change:
- Drain the old fluid into a pan.
- Replace the transmission filter if applicable.
- Refill with new transmission fluid to the correct level.

4. Inspect and Repair Drivetrain Components

Tools Required: Jack and jack stands, torque wrench, socket set.
Safely lift the vehicle and inspect the driveshaft for any play or damage.
Tighten any loose bolts on the driveshaft and differential.
Replace any worn or damaged components as necessary.

5. Wheel Bearing Inspection

Tools Required: Jack and jack stands, torque wrench.
Lift the vehicle and check wheel bearings for play.
If excessive play is detected, replace the wheel bearings as follows:
- Remove the wheel and brake assembly.
- Remove the hub assembly and replace the bearings.
- Reassemble in reverse order, ensuring all components are torqued to manufacturer specifications.
