How to replace the Rear Crankshaft Seal Housing on Chevrolet S10?

Start the crankshaft rear oil seal housing replacement by removing the Oil Pan then the Transmission Assembly followed by the engine Flywheel. Start by removing the bolts and nut that fasten the crankshaft rear oil seal housing to the engine before extracting the housing itself and throwing away the gasket. Clean all sealing surfaces before checking the housing for warping or damage or cracks or wear by replacing it if any defects are found. New crankshaft rear oil seal housings should ship with an integrated oil seal. When keeping the housing you should install it per the manufacturer guidelines and add a fresh replacement seal using the crankshaft rear oil seal documentation. After implementing the new gasket start by putting in the new crankshaft rear oil seal housing with its oil seal on the engine block while avoiding oil or grease application on the seal lip or Crankshaft Seal area. The sleeve in the crankshaft rear oil seal functions as a tool to help the seal lip glide onto the crankshaft end before you apply full force to push the housing until it touches both the gasket and engine. Put the sleeve aside when you screw on the bolts and nut while tightening them to 12 nm (106 inch lbs.). Reinstall the engine Flywheel and Transmission Assembly and Oil Pan at the end of the procedure.

The Crankshaft Seal is a major Chevrolet S10 component which is situated in front of the engine, generally designed from metal and rubber. Its main use is to avoid the oil loss from the crankcase and to circulate the oil to the other parts of the engine so as to decrease friction and wear and tear. Cranking Seal failure symptoms are high mileage, and oil leakage, hence the need for a change. Various models of Chevrolet S10 trucks use different types of Crankshaft Seals depending on the model's year, however, their fundamental use remains the same- to enhance the durability of the engine.
