I haven't found any vehicle review YouTube channel that does a "great" job of the technical details, but maybe that's because any that try it don't get the clinks. Remember, YouTube is an entertainment business, and being informative is a secondary goal for most channels.

Now, if they could hire some non-idiots to speak on camera, all would be well.

Looks like the Sterling is the way to go with the 7.3 after all.
All in all TFL has improved over the years but I agree they don't give true enthusiasts anything to write home about. At least their early access to new production vehicles is nice.

I would take a Sterling axle over the the Dana m275 any day. The new Dana axle has very little aftermarket support, and what is available is expensive. The Sterling 10.5 has tons of aftermarket support, there are dozens of limited slips, lockers, and gearsets available for it, and it is one of the cheapest HD axles to buy parts for.

The best bet for better mileage is a long tow; as in a couple of thousand miles. The differentials need to loosen up to get better mileage.

That makes little difference, a new differential shouldn't be tight, the pinion pre-load is only 20-40 inch lbs on most axles, which is very little, considering the weight and wind resistance of the truck.

I've never noticed much of a difference break-in, and 12 sounds about right for mix driving. Have you paid attention to the mpg meter while cruising on the highway?

Yes, I agree. IMO, the differentials get worked in . . . close to 2 MPG improvement in my case. The break-in Ford wants before towing is for the differentials, not the engine. When my truck was new, releasing the throttle was like throwing out a huge boat anchor. Now it will coast somewhat better.

That could still be the case with new engines. Outboard marine engines are the same way.
