Front and rear gears

Good lord.




I seriously reccomend learning how these new fangled trannys decide when to shift.

Good lord, mechanical advantage through gear swap.

If gearing makes no difference, why does the Bronco have different gearing options with different tire sizes? By your logic, changing the shifting strategy would overcome the difference between 31” and 35” tires. Why would ford bother with different gears? Why would anyone regear on any vehicle?

The truck will "see" that mechanical advantage at cruising speed and shift up so its working within its desired parameters..

Low speed off road performance... the opposite of the OPs complaints and not any at all relevant.


My bronco came with 32"s and I shortly after installed 35"s.. end result is a higher (lower numerically) final drive.. by a meaningful amount.


Using the logic in this thread.. my cruising rpm should be a shuddering sub-1k rpm discomfort right?

But no... the Bronco "sees" this mechanical disadvantage and I'm simply down 1 gear while cruising, compared to stock tires.


Lowering the final drive (higher numerically) WILL have the opposite effect. This ain't 1985 anymore.. and thus.. shit that 'worked' back then doesn't necessarily work now.


Again.... Algorithms.

Maybe not. It tends to cruise as low a 1400 rpm in 10th. Unless I give it more than 50% throttle. Then it will downshift. I'm not looking for that. Part/ light throttle non boost acceleration is what I'm after. And gears will do this exactly.

If your gripes about cruising rpm are strictly in top gear, than gears would indeed cure what ails you.

Thinking they're going to help alleviate lugging in anything but 10th though... please dont.

seriously... save yourself thousands and just have the tranny tuned. While all this new electrical nonsense that fills vehicles nowadays CAN be a huge headache... it also opens up AWESOME opportunities that weren't available 'back in the day'

The simplest solution is often the best.

In case you missed it I'm tuned. For years. Yes that's exactly why I want them as I described. That's why I want them. I've never once said it was anywhere else other than in 10th. Again, the point is the thread is to accomplish gear swap regardless of anyone's reason because no one has done it on the front diff. Trying to verify that the front can be done. That's it. I've easily got couple grand to throw at gears and have my solution. Not to mention more acceleration through every gear.

So if I have the Electronic Locking Diff and RWD then I can order the 4.46 gears and install kit and be good to go? I have 35's. Last time I checked there wasn't anything to buy for gears lol.

Yes, the M220 rears are known to be compatible. The front is what's been the unknown part.

 

[Friday yet?]

Well, I read this entire thread off and on this morning while working and getting my caffeine fix. And I have less than zero interest in regearing my truck!

Had quite a few immature chuckles at some of the smartass comments. Yes, even at my age I stand ready willing and able to embrace the entertainment value of smartass, petty and down right useless angry comments. Be it internet forum or real life. (Been there done that a time or two myself. )

All that said.... this thread is quite educational. In my case it served as a stark reminder of how the forum always benefitted from the input of D Fresh. IMHO. And his smartass, at times, delivery style.

Good luck with the desired gear swap OP. Fingers crossed you are able to make it work for the front diff.

I hope you get better answers than I have so far. I'd love to regear.

If you want oem m190 rehears you’re still limited but at least look into fords part numbers you can get the m190 pumpkin and transfer your tube and you won’t have to cut or modify anything. I think base bronco m190 had about 3 offerings when I was looking into it. The pumpkin alone was in the ball park of 700. I say about a 4-6 hour install for someone competent or if you’re thinking of having it done.

You heard it here first. It's done! He forgot to take pictures of the front while it was apart. Going from 3.73 to 4.46 gears made a huge difference. All the high gear lugging is gone. In fact the instant MPG's shows higher like I expected. Crises at 70 mph so much easier than it did at 55 mpg with the stock gears. I'll record it on the next full tank. Side note is said that all open diffs have welded ring gears. As shown in the pictures it turns out the front on mine were bolt on after all. Could have saved a good chunk of money had I known that. I can only say that's what mine came with. Your mileage may vary. Since this is now confirmed that you can swap the gears listed for the Bronco M190, a dana engineer told me you can run any of the stock bronco gears, you should be able to run up to 4.46's in the M190 before you need a different differential case like the M210.

This is great news.

Do you mind linking the actual parts you used, and perhaps what you think you could have gotten away with knowing what you now know?

I’m happy to be proven wrong! I agree with the above, please provide a list of parts so we can follow your path.

These are from Dana's site. It seems they may have removed some listing since I last looked? But I don't see the listing for the ELD front anymore on some ratios. You can still use the open welded version as I did. And choose your rear based on whether you have ELD or open. Availability of the gears themselves are kind of scarce since not many people and no ranger owners know these will work. You'll have to do a bit of searching. These are the cheapest installation kits a could find by a large margin.
This is the front installation kit: https://www.drivetrainspecialists.c...bronco-dana-m190-fdu-bearing-install-kit.html

I found the ford racing gears listed for the ELD bronco for the rear and ordered the front open diff part from the dana site through jegs. Installation kits listed above.
