    Q:
    How to replace the Rear Crankshaft Seal Housing on Chevrolet Express 2500? Posted by Customer
    A:
    The crankshaft rear oil seal housing replacement requires removal of the Oil Pan together with Transmission Assembly and engine Flywheel. Coverage begins with removing the bolts and nut which hold the crankshaft rear oil seal housing in place before you remove the housing altogether. Toss the gasket. Check all sealing surfaces and examine the housing for evidence of warping as well as cracks or wear or damage before proceeding. During crankshaft rear oil seal housing installation use a new seal together with it and apply no oil or grease to the new seal lip or Crankshaft Seal area prior to installation. The sleeve inside the crankshaft rear oil seal serves as an installer guide to help glide the lip past the crankshaft end so you can push the housing until it contacts the gasket and engine. Secure the three bolts and the single nut to 12 nm-torque (106 inch lbs.-torque). Afterward replace the engine Flywheel together with the Transmission Assembly and the Oil Pan.
