How to replace the front crankshaft seal on 2004 Chevrolet Express 1500?

The process to replace the crankshaft front oil seal demands initial removal of the crankshaft balancer followed by extraction of the crankshaft oil seal out of the front cover. A proper replacement of the crankshaft oil seal requires avoiding both surface lubrication and seal reinstallation. Motorists should apply clean engine oil to both the outer part of the new oil seal and the bore of the front cover. Insert the crankshaft front oil seal onto the J41478 Crankshaft Front Oil Seal Installer (J41478). Through the J41478 threaded rod structure (with nut, washer, guide, and oil seal) you can correctly install the oil seal into the cover bore by placing it into the crankshaft end. A wrench stabilizes the hex on the installer bolt to let you tighten the installer nut in a clockwise direction until the seal reaches full insertion into the cover bore. Users should uninstall J41478 and verify proper alignment of the oil seal inside the front cover bore after the installation process. Finally, reinstall the crankshaft balancer.
