How to replace the front crankshaft seal on LMG, LY2, and LY5 engines on 2007 Chevrolet Silverado 1500?

The replacement of crankshaft front oil seals begins by extracting the crankshaft balancer followed by the removal of crankshaft front oil seals which are located at the front cover. Replacing the crankshaft front oil seal requires avoiding both lubricating its sealing surface and using the same oil seal again. Start the installation procedure by treating the new oil seal edge along with the front cover bore with clean engine oil. The Crankshaft Front Oil Seal needs to be mounted onto the Crankshaft Front Oil Seal Installer (J 41478) guide. Connect the J 41478 threaded rod containing a nut and washer as well as guide and oil seal to the crankshaft end before using the J 41478 to position the oil seal correctly inside the cover bore. Wrench one hand holds the hex part of the installer bolt while another wrench turns the installer nut clockwise to achieve proper seat of the seal within the cover bore. Check the front cover bore for proper seal installation after removing J 41478 and examine the oil seal for complete and even positioning in the bore. Finally, reinstall the crankshaft balancer.
