2007 GMC Envoy Parts Questions & Experts Answers

• Q: How to replace the rear differential cover and gasket on a 9.5 Inch Axle on 2007 GMC Envoy?

  A: Before starting the replacement process of the rear axle housing cover and gasket on a 9.5 inch axle you must first raise and support the vehicle. First remove Drain Plug with a combination of the rear axle cover bolts. Then separate axle housing cover from gasket for installation. You should replace the axle housing gasket only when you detect damage but it remains reusable in other cases. Follow the procedure by applying the axle housing cover gasket before putting on the axle housing cover . Follow up the mounting bolt installation stage by tightening these bolts to 40 n.m at 30 lb ft. Complete the installation of the Drain Plug by tightening it to 33 n.m (24 lb in) before adding fluid to the axle which must remain between 0-13 mm (0-0.5 inch) underneath the fill plug hole. Use proper fluid to fill the rear axle with lubricant until it reaches the bottom of the fill plug opening or the fill measurement establishes a level that is even with the bottom of the opening. Finally, lower the vehicle.
