- Raise and safely support the vehicle using jackstands.
- Remove the filler hole plug.
- Being careful of sharp edges, insert your finger into the filler hole. The lube should be within 1 / 4 in. (6mm) of the bottom edge of the hole.
- After checking the level, make sure to reinstall the filler hole plug. Tighten the filler hole plug to 27-33 ft. lbs (37-44 Nm).
- Lower the vehicle.
