Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is turned off.

  • Tools Required: Socket set, belt tensioner tool.
  • Torque Specifications: Refer to service manual for correct torque values when re-installing tensioners.

4. Examine and Replace Differential Fluid

• Locate the differential cover and remove the bolts using a socket set.
