I have a 2011 stock 6.2L Raptor and it started making a noise that sounds like a main bearing spinning when you are moving and its got a load on the engine in the lower RPM band. It happens when it is "lugging" in any gear. If it is in park you can rev up the engine everything is normal. We have had it on the lift and "brake standed" it (really unsafe) and nothing. Ive taken it to 3 very good shops, including a very good transmission shop, here in Denver and they all give up. It stumps them so much that they dont even try to charge a diagnostics fee or anything. I was just hoping maybe if I posted it on the forum, maybe someone has already been through this. I realize it is a long shot but it is worth the keystrokes. Thanks in advance for your time.
