Is it really the trans ford is protecting?

[OX1]

10 speeds between F150 and Bronco seem about the same ratios (with the very slight edge going to bronc in 1rst/2nd).

The big difference is after that. 3:1 case, 4.7 diff, and a rear D44 for the Bronco. (see above)

Yet the F150 gets at least an 8.8 and many come with a 9.75.

So even if they are the same weight vehicle, it could be the rear diff that Ford
is trying to protect.

The ECO's, after the turbo lag, ramp up the torque very quickly. Possibly too quick, especially
in first gear when you are talking almost 70:1, overall ratio, and heavy 35's (which yes does knock down
the effective ratio some compared to F150).

Heck the D44 was the FRONT diff in every FSB ever made (about the same weight as a loaded 4 door bronco),
and those supposedly have total POS engines compared to the Broncos offering (according to at least 30 % of
he people on here).

Anyway, just another thought on a possible reason for the nannies.

Very unlikely.

The Germans have some stupid powerful turbo engines without any such problems.

They aren't running that kind of differential gearing or anything close. Gearing is a torque multiplier.

What is the weakest link in the 4x4 system and driveline? Bronco has less room to spare hence smaller assemblies that have a lower failure threshold. Also, trans has a couple less friction disks than 10R80. My opinion.

Is this where I say…Mall Crawler? LOL.
Look at that beast, I’d have so much fun getting in trouble with that.

I'm not sure if the part about half shafts still holds true or if I misunderstood the Ford accessories description of their half shafts.

The new Advantek D30 and D44 should of been given new designations.
Comparing them to the older axles is like directly comparing a G6 Bronco to a EB, because they share a name too.

That said, the M190's center differential is actually rated by Dana as being stronger than the new Jeep D44.
The M210 is significantly stronger.
The pinion teeth of the M190 and M210 engage the ring gear closer to the center of the gear.
The D44 and D30 have the pinion closer to the top, for driveshaft clearance.
This puts more deflection stress on the D30/44 pinion.

Also, the ring gears use an new convex curved tooth shape, that increases the % of ring gear and pinion tooth contact, while reducing friction.

As @Apples has said, the CV joints are going to be the weak link in the front axle.

The good news is that the Ford engineers made the Sasquatch CV size the default half shaft for all Broncos.
Also, there is only one half shaft.
It is interchangeable L/R, Base to Wildtrack.

Finally, Ford has stated that the Bronco is easily lifted. Just like the Wrangler.
Ford Dealers have watched Jeep Dealers get fat and happy putting MOPAR warrenty approved 2" lifts and 37" tires on Wranglers.
Either straight off the showroom floor, or as a used sale still under warranty.

Ford has directly stated that Bronco dealers will be able to get in on this action.
Big money is at stake.

All of this means that the Bronco hard parts will handle 37" tires.
Just add lift and rubber.

M190 Broncos will be like D30 Wranglers. 35" if you are lightfooted on the trail. 37" if it's a mall crawler.

M210 +37" will be gtg for the lightfooted.
We don't know yet if the 40" tires will be usable as a mall crawler without heavy modifications to things like the ball joints and steering.
Probably not. The 40" donuts are very heavy.

M190 front axles and aluminum front diff I would bet. Factory Engine/Trans calibration has to be safe for those parts.

The Bronco rear differential is the same size as the 2.7L F150 (8.8"/220mm) but a 4.7 ratio gear set will be weaker than a 3.55 set due to the smaller teeth so there's a possibility it's that but I doubt it.

I'm wondering if it might be a worst case dynamics thing, like torque steer in 4A when the front drive kicks in. If so, you would hope it would only limit torque when in 4A or 4x4 but after hearing Esteban try to explain the GVWR calculation method I would be surprised by nothing.

The transfer case clutch is another potential weak point. The F150 has similar so probably not that.

Hopefully it can be easily tuned out but with how connected these things are I assume Ford immediately gets a "void all warranties" message when doing so

GWagen, first Gen Cayenne and Touareg.
