Hope so too, congrats on a solution for you. Still shocked that replacing this entire component and full disassembly of the front drive line is even remotely more cost efficient to replacing the needle bearing itself unless this is an interim fix / update to the TSB as they try to rule out bad production serial numbers of the diff, who knows. Typically the manufacturer would start with the easy parts and make their way into the entire assembly if necessary its just bizarre. And yeah, I can't see the new units having a different type of needle bearing? What - few thousands more on the thicker side ? Can't see that, someone out there would have noticed the revised part by now in all of these forum discussions. I still think the only fix is that ECGS solid bushing to cradle the CV properly from what I've seen on youtube videos and such. As for the rear end noise I guess I can hear that harmony too depending upon speed and load on the drive line but its not different from other trucks I've driven, some gear cuts are gonna whine more than others (Fords seem to be quite loud in fact), is it the cuts? The oil viscosity? The housing itself which lends itself to creating these hums? I really wouldn't worry about the longevity of the driveline on these things - like that wonderous tick tock at idle - just love it or leave it... I'm sure once I get rid of these vault quiet Dueller tires and into a proper semi off road tire all of these noises will quickly be solved LoL
