What all will interchange with the rearend you need them for??0 -
Pat McDonald in England makes the 3-5/9 rearend gearsets, though (depending upon the exchange rate between UK / US) they're not inexpensive. Figure about $600 give or take. This ratio was available as a "service" item for the 1937's, but of course they're scarce as hens' teeth. I believe these have the 6 bolts, which will fit up to '39 ('40?) after when they changed to 8 bolts (because the 6 bolts kept shearing off).0

Don't have any idea , have never opened it up , don't even know what it is called . . The complete rear end was said to have come from a 51 Hudson . ----Was told of a 77 Int. SCOUT with a Danna 44 in it being stripped . Will that ring and pinion go in mine ? SAME NUMBER OF BOLTS ?0 -
If you've got the Dana 44 (removable cover plate type) already under the car, there are a number of ratios available. Reider Racing is an excellent source for the gear sets. Sounds like something around 3.5 to 3.7 would be about right. The other approach would be to install the earlier stepdown type axle ('48-'51) with the 3.58 gears used in '51 for the Hydramatic-equipped cars.0

sounds like you probally have a Dana 44 if it has 3.07 gears now, Im not up on Dana 44s but at some point the pinion went to fine spline , Im guessing the the Hudson 44 uses a coarse spline pinion- Id about bet a 77 Scout has the fine , something you might watch for , something from the 1960s and back would be coarse spline.You might need a different ring carrier if the ratios are much different from each other too, there are alot of ratios out there for Dana 44, 3.73 would be as high as Id go.0 -
From info here and there I do have a Dana 44 , anyone know for sure about spline changes ? From what I've found out so far ALL the Dana 44's are the same . Even if there was a spline change it could be handled by useing a matching yoke , all kinds of U joints availeable . BUD0

I think the Dana 44 is very popular in the Jeep world. You might try searching the Jeep forums for someone switching out gear ratios. Just a thought.

When I got my 3.73 gears from Robinson Racing, I did have to get a fine-spline u-joint yoke, but they have them and they're not expensive.0

I'm finding the Dana 44 was widely used , which keeps the prices down , good cause my engine has really set me back,
PARK , I'm thinking the 3:73 is still a bit too tall for a 212 engine . What engine do you have pulling it and what do you think about useing it with a 212 , want to get as high as reasonable and still be driveable without strugling on power , the 3:07 is too much for it , kinda lazy even on flat roads . Got a mix of flat and small hills in my area . BUD0 -
Dana 44 is still in production. You can buy ratios at the store brand new in a choice of ratios. They are not $50, but not outrageous.
And to add a little about the 3.5:1 gears Pat MacDonald has made in England. I have been getting them from Pat in batches of five and have only one left for sale and I believe he has none left--and no plans to make another run of them. Jon B. is correct in the price of $650, but that is in England, so you have to add shipping and duty to get the real cost. I sold them for $850 including shipping and insurance in the US and figure I might have lost a couple of bucks on each one!

Here's another source for ring and pinion sets for the Dana 44:

Bud, I don't think the 3.73 is too tall for a 212 engine. In fact, I'd use the 3.54 that's available for the Dana, or change out the axle to the earlier stepdown unit with the 3.58, which would be more work but less expense. I've not heard anyone who's using the Brit-made 3.5 gears complain about their being too tall. I'm using the 3.73 gears in a Hornet, but that's with overdrive. By the way, my source was Reider Racing, not Robinson. The 3.54s from Reider are listed at $212. According to their listings, your differential case will handle any ratio up to and including 3.73, so there'd be no extra expense there. The Dana's do require a bit of special knowledge and a special tool to set up, so you may not want to tackle the gear swap yourself. The good news is that Dana 44s have been used in recent model Chevys and Fords, so most any dealer would have a competent guy to do it.0

My son used a 4.11 in his '46 pickup with OD. As I figure it, this would have been about equal to a 3.09 ratio. That old truck didn't seem to have any problem in hills or even the eastern US Mountains - was far from lazy. This truck by the way used the original style 7:00 x 15 truck tires which are somewhat larger in diameter than passenger car tires.0

I've set up a number of differentials , but allways with the parts called for on the vehicle working on , no problem there . A Hudson guy I've been helping { for free } has offerd to give me the complete rear end from a 51 parts car he has that was automatic at one time and changed to manual tranny . If it hasn't been changed that should be the 3:58 then , correct ? Gotta get it out of the briar patch a few miles away and look at it yet . As far as the 3:07 goes 1st 2nd gears it really gets with the program , 3rd not too bad on the low end , about 60 or so you run out of the better torque range and that's where I think I want a bit more acceleration to deal with highway traffic , {passing} , and some of the hills . Thank all of you guys for the info . BUD0

Hey Ivan,
As much as I would love that set, its just a bit out of my reach.
Whats the possibility of getting the molds from England and getting the castings done here in the US? With as many great shops and companies that we have here I would think it would be worthwhile for someone to do it!

possibility ? http://www.empiremotorsinc.com/
I've just started working on the rear end for the 37 PU. I have two different ones to work with, one is the 8 bolt discussed and the other is from a model 71 that I think is a 3:89 ratio. The model 71 rear is from the west and has a real nice housing. The 8 bolt is a 4:19 and the housing is pretty rusted-pitted.
So I think I am going with the nicer 71 rear.0 -

The PU was a 4/59 ratio and pinion pitted pretty badly, the model 71 was a 4/59 , went to a local Hudson guy to pull one from a 47 sedan and found it was shot with ring cutting a hole out the back of the housing! I guess the owner just kept driving it- not paying attention to the noise in the rear! Got another rear end from another 47, tore it down, ring and pinion pitted badly like it had set in water for awhile. So now, I'm back to square one, looking for a 4/10 ratio ring and pinion that will work in the 37 PU.0 -
Dang , I had it all, sold it to another member that only needed some parts from it ..Check your email for how to contact him , { don't want to post without permission } he may have what you need left over from his job . He had another rear end he could not use for some reason also , talk about both . BUD0

I have a diff. from a 65 Dodge with 3:73 gears in my 37 Terraplane coupe. It's just a tiny bit slow on start out on soft ground but it cruises along great on the streets and highways.0
