Thanks for the reply,the engine is the 4g54 with a balance shaft,the pump isn't in the pan so I guess on the front of the engine.I didn't have time to take any other bearing caps off but I'm sure they are in the same condition.I was hoping something just failed in the pump and didn't do too much damage to the rest of the engine.Any idea what all is involved in taking out the engine(does the engine and trans separate in the truck) or does it all come out as one unit?I was hoping this was going to be a quick fix and nothing major wrong but so far maybe I should have left it there...
