Here's my story. 2013, 157", no mods. My truck is smooth all of the time. And I use it to haul and pull. And I've pulled some pretty heavy loads in my 12' dump trailer.

 

Just FYI on the Raptor trans mount:

I ordered a Raptor Trans mount for a 2010 F-150 with the 5.4 liter engine based on various things I have read on here and elsewhere that this was the one we needed for our trucks with the Ecoboost engine.

This mount DOES NOT WORK. It mounts in a completely different way. So I threw 28 dollars in the trash in order ship a 79 dollar part back and forth........

Soooo, if the dealer wouldn't mind telling you a part number if they do decide to install one in your truck, please post it here!!

TIA

 

Mine is a 2013 5.0L FX2 and has has the slip yoke greased twice. Was there at the dealer today and told them it's starting again. Said there was nothing they can do, that Ford hasn't changes the grease again. Can someone please post the Raptor part # that will fit my 2013 5.0L FX2?

Holy ****! Yeah mine doesn't so that. I just feel a little thump when taking off from a stop. That looks horrible! Any chance you can do that same video but while shooting the camera at your pinion from the side? I'm wondering if your getting a lot of axle wrap.

The thump is the slip yoke not slipping smoothly.
These slip yokes NEED a zerk grease fitting.

As one of my fixes, they replaced the driveshaft and my thump has been gone for over 3000 miles.

 

Update.
The driveshaft/slip yoke thump is still gone, maybe for good.

I added a leaf to the rear spring packs. They are the 998# AALs. I have recently towed a couple of 7000# trailers and the slight quiver that I still had is gone due to the AALs.
