Yeah I like that video. I also looked at the GM version of the PTU using the same transmission. They don't have idler gear problems they have pinion gear problems. Again insufficient lubrication in the case for GM.Very good video explaining what's going on in the PTU. Only significant difference in our platform is the idler gear that sits in between the ring gear and pinion gear inside the PTU. It's this idler gear, or more specifically the bearing for that idler gear, that has been the culprit for many of the PTU failures. Hence, the many attempts by Ford to implement updates to it. The most recent iteration, combined with regular fluid changes, can drastically mitigate PTU failures, even at higher power output levels, in my opinion.
Thanks again for that great video!
