The rear Crankshaft Seal cannot be removed from the seal housing; both components are only serviceable as a single unit. Begin by disconnecting the cable from the negative battery terminal. Next, remove the transmission, followed by the
Flywheel/driveplate and the oil pan. After that, remove the retaining bolts to detach the seal housing from the engine. Thoroughly clean the mounting surfaces of the oil pan, rear Crankshaft Seal housing, and engine block to eliminate old gasket material and sealer, using a rag soaked in lacquer thinner, acetone, or brake cleaner. Install two threaded dowel pins to the cylinder block for proper alignment of the rear Crankshaft Seal housing. Apply a 1/8-inch (3mm) wide bead of RTV sealant around the mating face of the rear Crankshaft Seal housing, ensuring not to fill the bolt holes. Slide the seal over the crankshaft and dowel pins, then tighten the upper bolts finger-tight. Most new rear Crankshaft Seals and housing assemblies come with a seal protector on the inside running face of the seal, which should remain in place until the housing is positioned. Remove the dowel pins and install the remaining rear Crankshaft Seal housing bolts, tightening them to the specified torque before removing the seal protector. Proceed to install the oil pan and flywheel/driveplate. The remainder of the installation follows the reverse order of removal. Finally, add oil, run the engine, and check for any oil leaks.
