I want to do a rear main seal replacement and after researching the STS forum, I need to locate a J 45930-A Crankshaft Rear Oil Seal Installer and EN-48072 Applicator Housing and Pilot base. These tools are expensive so could I rent them versus purchasing? Does anybody have any of these tools for sale or rent on this forum? I'm not looking forward to this but I know it needs to be done. My 2005 STS with 4.6 Liter has over 120,000 miles and is showing a small leak. Has anyone successfully installed this one piece seal without these specialty tools? Any help or direction would greatly be appreciated.
