Step 2.1: Visually inspect the drive belts for signs of wear or misalignment.
Step 2.2: If damaged, use a socket set to release tension on the belt using the tensioner tool.
Step 2.3: Remove the old belt and install a new belt by routing it according to the belt routing diagram.
Tools Required: Socket set, torque wrench.

3. Check and Replace Transmission Fluid

Step 3.1: Locate the transmission dipstick and check fluid level. If low, add the appropriate fluid type (refer to owner's manual).
Step 3.2: If the fluid is discolored or has a burnt smell, drain the transmission fluid using a pan and replace it with new fluid.
Step 3.3: Reinstall the dipstick and ensure it is secure.
Tools Required: Transmission fluid, fluid pump.

4. Inspect and Replace Wheel Bearings

Step 4.1: Lift the front or rear of the vehicle using a jack and support it with jack stands.
Step 4.2: Remove the wheel and inspect the wheel bearing for play or noise.
Step 4.3: If worn, remove the bearing by using a bearing puller and replace it with a new one.
Tools Required: Jack, jack stands, bearing puller.

5. Inspect and Replace Differential Fluid
