Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Tire Inspection and Rotation

Sub-steps:
1. Use a tire pressure gauge to check the inflation of all tires; adjust as necessary.
2. Measure tread depth with a tread depth gauge; replace tires that are worn below 2/32 inches.
3. Rotate tires according to the manufacturer's specified pattern to ensure even wear.

3. Fluid Change

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the drain plug on the transfer case and differential; remove the plug to drain the fluid completely.
3. Inspect the fluid for metal shavings or a burnt smell; replace with manufacturer-recommended fluid if necessary.
4. Reinstall the drain plug and fill the transfer case and differential with new fluid, ensuring it reaches the specified level.

4. Inspect Driveshaft and CV Joints

Sub-steps:
1. Visually inspect the driveshaft for any signs of rust, cracks, or damage.
2. Check the CV joints for any torn boots or grease leakage.
3. If damage is found, replace the driveshaft or CV joint as necessary.

5. Final Checks and Reassembly

Sub-steps:
1. Reconnect the negative terminal of the battery.
2. Start the vehicle and engage the AWD system to ensure proper operation.
3. Lower the vehicle and perform a test drive to check for unusual noises or performance issues.
