• Q: How to replace the front crankshaft seal on 2006 Cadillac Escalade EXT?

  A: Start the crankshaft front oil seal replacement by taking out the crankshaft balancer together with the crankshaft oil seal from the front cover. Sealing the oil seal requires no lubrication at any point and the crankshaft oil seal must always be replaced with a new one. Apply clean engine oil to the external boundary of the fresh oil seal as well as the front cover oil seal bore. You should fit the crankshaft front oil seal on to the Crankshaft Front Oil Seal Installer (J 41478) guidance system. The J 41478 threaded rod with its included nut and washer along with guide and oil seal should be inserted into the crankshaft end for subsequent installation of the oil seal into the cover bore using the J 41478 installer tool. Apply a wrench to the hex part of the installer bolt while twisting the installer nut with another wrench until the seal settles completely within the cover bore. Follow the installation of J 41478 tool by examining the oil seal to verify full and even oil seal installation inside the front cover bore. Finally, reinstall the crankshaft balancer.
