WHAT FACTORY BEARING DOES MY ENGINE HAVE? 1997-1999: This engine featured a dual row bearing IMS. 2000-2001: These engines came from the factory with either a dual row or a single row bearing IMS. A single row flange measures 19.27mm deep and a dual row flange measures 13.34mm deep. 2002-2005: This engine featured a single row bearing IMS. Some late production 2005 models will have a non-servicable IMS. 2006-2008: These engines were fitted with a larger bearing, readily identifiable by the 22mm center nut, that is not serviceable without a complete teardown of the engine. Removal of the IMS bearing grease seal will ensure proper lubrication of the original bearing. If the engine in your car has been replaced, it will have whatever IMS bearing was in production for that model year of manufacture for the replacement engine. It is important to identify which bearing your engine has before ordering or attempting installation of a replacement IMS bearing. The correct kit must be used for your engine otherwise engine damage or failure may occur.
