Unfortunately, it seems that the aftermarket has been slow to develop differential options for the Dana Advantek axles. I think its been hindered by the fact that both Ford and Jeep are referring to them as "Dana 44", which they are most certainly not.
I can't speak for anyone else out...
Audi's system is full-time AWD, not locked together 4WD. And for most of their vehicles, that hardware comes from my employer.
4WD & AWD functionally improves one aspect of driving - the ability to accelerate. This can lead to misjudging how good traction is and overcooking it. Most people...
Typically there's a face (dog tooth) clutch or a sliding spline that is engaged. That provides a mechanical connection that can't slip unless something sheers.
Greater fuel consumption. That is the whole reason the system is automatic on-demand rather than actually full time driven. Doing that induces a lot more system drag, and thus reduces fuel mileage. Some vehicles still offer that - many Audis do, as do Toyota / Lexus models. The 4Runner Limited...
Well, yes and no. AWD means a lot of different things to different people. What it means here is that it will automatically (and somewhat pre-emptively) drive the front wheels as required. It does this by engaging a clutch in the transfer case. In the moment it is doing that, the front is...
That's not the same thing as a center differential. What you're talking about disconnects one of the front CV shafts from the front diff when in 2WD so that the front diff / ring & pinion / prop shaft can all stop rotating and not add system drag.
A center differential is a diff in the...
If there was a center differential, it would be locked in 4HI / 4LO. That's the way the 4Runner full-time case is, for example. However, there isn't a center differential. On Bronco's base t-cases, it is simply either engaged (locked in) or not. On the 4A t-case, it has a clutch to drive the...
The issue isn't the speed itself. But the lack of differentiation is an issue. The front end always goes around a larger radius in the turn than the rear, so it goes around corners at faster wheelspeeds than the rear does. It is not balanced out by doing the same turn in reverse, the geometry...
This is a situation where you'd wind resistance torque into the front drivetrain. This is released once you go back into 2WD. This won't hurt your transmission. Over time, though, repeated behavior could fatigue the front prop shaft and the transfer case. If it were extreme enough, it could...
FWIW, I have experienced CV shafts walk/work out of a differential and disengage while driving due to a worn down circlip. This isn't a terribly different mode of failure here, so I still think its possible. It does seem generally unlikely, but I'm a "never say never" sort. If there's enough...
Its worth noting that the Jeep's Dana 30 or M190 is structurally quite different from the Bronco/Ranger M190. The clamshell aluminum construction of the IFS version probably isn't as robust as the solid axle design. If nothing else, I would think the IFS carrier could flex more, which translates...
I find the lack of circlip to be highly unusual. I have seen old CV shafts that it was easy to pull the shaft out of the joint because the clip had gotten weak if you pulled on them enough. It could be that without the clip, the normal cycling of the suspension was enough to tug it out of...
The lock solenoid is a magnetic coil that sits under the right side journal bearing on the locker carrier. If you open the axle, pull the locker out, pull the (pressed on) bearing off, then the solenoid should relatively readily be popped off. I think it's kept on with spring keepers. I'm not...
So far, I haven't seen where the lock solenoid is even shown in the parts listing. This isn't a new component, its been part of the Ranger's locker for a number of years. I'm not sure that Ford is keen on selling this one. But if you do find a PN, I'd love to know...
I know that, I said as much. The point of my post, though, was contesting your claim that center diffs can do none of things you outlined, not about what was in the Bronco t-case. That was why I said it was a tangent discussion.
Yes, the spline connection is the dog clutch I referred to. That...
Not yet. I'm going to have to buy one I think. But I need to buy the Jeep version of the diff carrier to see what the bolted ring gear version looks like.
I have looked at pictures of ones that have failed in the field, which is why I raised the question above. For the casual user or person...
What you described is how it works. As I noted previously, its basically the same as what is done in F-150 Raptor and Expedition. No real new ground broken here, but those systems are pretty well understood. There is a clutch to handle the AWD functionality, and I expect a dog clutch to...
