  Q: How to replace the rear crankshaft seal on Chevrolet Suburban 2500?

  A: Mount replacement of the Crankshaft rear oil seal requires the disassembly of the Flywheel. The installer positions Crankshaft rear seal puller (J 43320) over guide pins from Crankshaft rear seal puller (J 43320) which have been inserted into the Crankshaft. Using a proper drill install eight self-drilling sheet metal screws across the rear Crankshaft Seal in a cross-pattern. The Crankshaft rear seal puller (J 43320) includes eight self-tapping screws for its installation. The Crankshaft puller assembly requires threads through its central bolt that slips into the Crankshaft to extract the seal. The guide pins should be extracted from the Crankshaft once the seal is removed. Confirm the Crankshaft has no surface abrasions or loose rust or burrs before moving ahead with assembly. Make all necessary corrections beforehand. Dampen the Crankshaft sealing surface with a slender drop of oil while excluding oil from the engine block's sealing surface. Place the Crankshaft rear seal installer (J 42849) on its seal before setting it against the Crankshaft and tightening screws into the facing tapped holes. Using a screwdriver, clamp down the screws on the Crankshaft rear seal installer (J 42849) firmly to achieve square alignment over the Crankshaft before rotating the center nut until complete bottoming occurs. Remove the Crankshaft rear seal installer (J 42849) then reinstall the Flywheel.
