The plug to check the rear differential fluid in your 1990 Chevrolet 1500 Pickup should be on the right side of the differential, above the casting support web. The plug is 3/8 square drive so you can remove it with a socket and short extension. The fluid level should be to the bottom of the hole when the plug is removed.
