What type of rear differential fluid does the 2003 chevy tahoe use?

SAE 80W-90 Premium Rear Axle Lubricant by Motorcraft is recommended to use in the 2003 Chevy Tahoe rear differential. The rear differential is responsible for changing the direction of the power, so it is no longer along with the car or longitudinal. From there, the differential directs that power to the wheels. The differential contains gears that help with thiS90-degree change of direction on the rear axles.Changing the differential oil is one of the most-overlooked maintenance tasks on trucks. Because the differential is at the rear and under the car, it gets none of the star treatment that the engine up front does.But if lubrication in the differential fails, You won't be getting very far for very long. Fortunately, You only need to change this oil every 30,000 to 50,000 miles.
