    Q:
    What is the process for installing the rear main Crankshaft Seal on the 1988 Jeep Cherokee? Posted by Mikheil M.
    A:
    For 1984 V6 engines, a specially designed one-piece seal is used, which must be installed before final crankshaft installation. Apply sealer to the seal and push it onto the crankshaft using the installation tool. Align the seal with the groove in the block and remove the tool. Apply sealer to the end surfaces of the rear main bearing cap and install the caps. You can Select Your Vehicle to see complete installation and repair tips.
