On saturday I did fluid and filter change on my 08 Ram 1500 with a 545RFE. The truck only has 34,500 mi on it. The 545RFE has 2 filters, a traditional pan-type and a spin on that's inside the pan. The pan-type two halves started separating. The bottom half is metal and it's edge is rolled over and crimps down on the plastic top half. It was the original MOPAR filter. Sorry I don't have any pictures I have failed all of you. What could have caused this? I'm the second owner got the truck in August with 19,000 on it. I know the original owner and he never towed or overloaded or plowed and I have only towed an ATV a few times. I think it was a defective filter and probably started separating quite some time ago. Any thoughts
