How to replace the front crankshaft seal on 2007 Chevrolet Silverado 3500 Classic?

Start the crankshaft front oil seal replacement by detaching the crankshaft balancer and the crankshaft oil seal from the front cover. Using oil on the oil seal sealing surface is not allowed and this job requires the use of new crankshaft oil seals. The first step requires you to apply clean engine oil on both the new oil seal outer edge and front cover oil seal bore. The operation to install the crankshaft front oil seal requires J 41478 Crankshaft Front Oil Seal Installer (J 41478) step-by-step. The installation of the crankshaft requires the J 41478 threaded rod with its components (nut, washer, guide, and oil seal) to be inserted into the crankshaft end before applying J 41478 to position the oil seal in the cover bore. Use one wrench to maintain a secure hold on the installer bolt hex before using a second wrench to turn the installer nut clockwise. The operation should continue until the cover bore holds the seal entirely. Check that the front cover bore contains the oil seal properly and equally after using the J 41478 Crankshaft Front Oil Seal Installer. Finally, reinstall the crankshaft balancer.
