You could be right, as I said, its not my area. That's just what I've been led to believe by people that are closer to it than I am... 🤷‍♂️

FWIW, that specific LSD won't work here. That's for a "traditional" Dana 44, not the modern Advantec M220 axle sometimes called a Dana 44. But once somebody makes something that fits the M220 (if they haven't already), then your general principle will still hold. A diff made for the axle, paired...

I'm under the impression that its more to improve the life of the solenoid itself rather than what heat it would add to the sump. Again, this isn't my part of the business, but I'm lead to believe that the coil being hot for extended periods is a detriment to it.

Well, there's a little more to it than that. There would also be separation forces between the lock plate and the side gear, since the face spline has a slight pressure angle to it. Putting a torque across that will result in a thrust trying to push them apart again. Couple that with the...

I don't know the ins and outs of the controls. I'd have assumed that they're stepping down the voltage so that the available amps are reduced. But again, I'm a gearing guy not a double-E. I'm sure there's a body control module that's running the show, though.

Well, either way, I'm curious as to where this thread will lead. I'd be surprised if this sort of thing doesn't also carryover into the Ranger community.

I entirely understand and can get behind the logic of this argument. But...why on earth would they market these by way of Ford Performance if there was no intention of upgrade swaps? Ford already has a dealer parts network for selling direct replacement parts. Ford Performance's entire mission...

Vikingnene, I think your post would get more attention if you started a new thread to ask about this. It seems like someone must have dabbled in this already, but if no one sees your questions because they're buried here, you won't get very far. Also, please try to break that up into some...

On a related note, I just got my hands on an M190 axle assembly from a Ranger. So I'll be digging into that in the next few weeks.

The short answer is yes, you would probably want to do this. Way back when my dad bought a new 1995 F-150, he had the truck's program updated when he changed tire size (same effect as a gear change). At the time, it was to recalibrate the speedo. That aspect still applies today, but it also...

The CRV and Mustang are IRS applications with structural mounting ears on the cover, if I'm not mistaken. The Tundra has, IIRC, a bolt-out third member. In each case, there isn't a simple cover that you can pop off for easy service because that part is actually load bearing. Same was true on the...

In this case, it extremely common. Uncommon, actually, is an axle with a dedicated drain plug, though I have seen it. IIRC, the rear axle on the Mazda 323GTX that I owned had a drain plug. So it was on at least one obscure Japanese car... :cool: I will note that the manufacturer does not fill...

No, it doesn't really change anything on that front. We've long said that the open diff has a welded gear, the locker is bolt on. This confirms that the locker is bolt on. That's all... If it were that simple, everyone would do it. :cool: Unfortunately, its not. I'll put aside the aspect of...

You could probably use a 4.30, but that's barely close enough. I'd be happier is it was a little closer. But even then, I don't see where there is a 4.30:1 available for the M190 either. What are the 4.27 gears you have from? I'd be interested to see what people are finding and what will...

Ah, well, when you go to install a replacement differential into the M190 (or at least the Ford version), you have to install a new ring & pinion gear set as well. You have to do this because in the Ford-spec version of the axle, Dana welded the ring gear to the diff housing. Normally, you would...

Just out of curiosity, who is making a unit for the 190? I think the tricky part of install is, as I mentioned before, where do you get the 4.27:1 gears that are bolt-on. I haven't seen that yet either.

That's interesting. I prefer the look of old-school round lights myownself, but I certainly appreciate companies that think outside the box for this kind of thing.

This is the locker that Ford uses in Bronco and Ranger rear axles. The gear ratio changes don't really have any bearing on the locker itself. Whether this is the same mechanism that's used in the Jeep version of the M220 axle, I can't say, but I suspect they may have a different design over...

Well, in principle, that would work. That's why I make the comment about doing just that as a field fix if the control module takes a dump. That assumes, of course, the coil was designed to be fed 12V and isn't stepped down to 5V or something. Without knowing the draw of the coil, I can't really...

The question will come down to how readily you can get the right gears for it are. Most of the ratios that Ford picked for these vehicles are unusual, with the exception of the 3.73s. But the Broncos with 4.70 only come with M210s up front, so no issue there. As I understand it, people with...
