Tabbed mine a few weeks ago, had come out about 1/4". Took my time - about five to six hours. Changed the water pump while I was at it. Dodge wanted $189. 00 for a new pump, got one from Cummins at $114. 00, also got the tabbed washer from them, $. 96 cents and a new crank seal and case gasket, all cheaper than the Dodge boys. Most time consuming part was removing the fan & shroud. Also drained the coolant and changed hoses. That little sliver of rubber is a dust cover I also had to ask - so much for directions. All working fine so far. Somewhere on the TDR web site I found instructions, don't recall where. Good luck.
