Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool.
Remove the serpentine belt by releasing tension with the tensioner tool.
Inspect the serpentine belt for cracks, fraying, or wear.
If damaged, replace it with a new belt, ensuring proper routing as per the vehicle diagram.

3. Check Transmission Fluid

Tools Required: Transmission fluid dipstick or fluid level gauge.
Remove the transmission dipstick and check fluid level.
If low, add the manufacturer-recommended transmission fluid until the proper level is reached.
If the fluid is dark or burnt, consider a transmission fluid change.

4. Inspect Drivetrain Components

Tools Required: Jack stands, torque wrench.
Lift the vehicle and support it securely on jack stands.
Inspect the driveshaft for any signs of wear or damage; check U-joints for play.
Check the differential for leaks or unusual noises during manual rotation.
If any component is worn, replace as necessary.

5. Wheel Bearing Inspection

Tools Required: Jack stands, socket set.
Raise the vehicle and spin each wheel to listen for grinding or abnormal noise.
If a wheel bearing is suspected, replace it using the appropriate tools and methods for the G70.
