moparfun Posted March 16, 2023 Report Share Posted March 16, 2023 Take measurements on the width of each rear axle and find the difference if any, in the Hollander it shows that 1953 and early 1954 are the same. The gear ratio is stamped on the carrier. Quote Link to comment Share on other sites More sharing options...
Crisjr14 Posted March 16, 2023 Author Report Share Posted March 16, 2023 Thank you moparfun and the carrier you are referring to where the stamp is at is this part here in the picture circled correct? Quote Link to comment Share on other sites More sharing options...
Veemoney Posted March 16, 2023 Report Share Posted March 16, 2023 Check this thread with pictures of where to find the gear ratio marked. They can be easily missed. Quote Link to comment Share on other sites More sharing options...
Loren Posted March 17, 2023 Report Share Posted March 17, 2023 Usually the ratio is stamped on the flat under the filler plug. The exact location, orientation and size of the stamps does vary as they were hand stamped. Quote Link to comment Share on other sites More sharing options...
Crisjr14 Posted March 17, 2023 Author Report Share Posted March 17, 2023 Thank you Loren for the information going to try and find them stamps on both rearends today Quote Link to comment Share on other sites More sharing options...
Crisjr14 Posted March 17, 2023 Author Report Share Posted March 17, 2023 OK so I got the ratio from both rearends so the 3.9 is on my 53 and the 4.1 is on the 54 so next question would be could I still use the 4.1 ad a swap and if someone could explain to me the pros and cons I guess you would say on this issue thank you Quote Link to comment Share on other sites More sharing options...
moparfun Posted March 17, 2023 Report Share Posted March 17, 2023 I'm not sure I understand your question. The 4.11 is a lower gear ratio than the 3.91, IMO the 3.91 with stock size tires will get you down the highway with the motor purring, the 4.11 would be for more around town. 1 Quote Link to comment Share on other sites More sharing options...
Booger Posted March 17, 2023 Report Share Posted March 17, 2023 make sure the the carrier and bolt number are the same to axle ' some are 10 some are 11 Quote Link to comment Share on other sites More sharing options...
Sniper Posted March 17, 2023 Report Share Posted March 17, 2023 Did you grab the speedometer pinion gear from the donor? Different gear ratios will affect the reading on your speedometer. 1 Quote Link to comment Share on other sites More sharing options...
Crisjr14 Posted March 17, 2023 Author Report Share Posted March 17, 2023 Moparfun I was asking if the 4.1 off of the 54 will work on my 53 that has a 3.9 in it. Booger I have no clue as to do that measurement you are saying. Sniper the speedometer pinion gear has me stumped as well so friends I'm not that mechanical just trying to learn as I go Quote Link to comment Share on other sites More sharing options...
Solution Los_Control Posted March 17, 2023 Solution Report Share Posted March 17, 2023 I think someone somewhere can give you the exact answer .... Long story short, you just need to try it & see. @Booger makes a good point on counting the the bolts to see if they are the same. Another issue could be the axle shaft diameter & spline count ..... Possible your axles will not fit this hogs head. I remember back when I was 25 years old, swapping one out in a hour or so on a 1960's dodge truck without a tapered axle in a hour or so. Only suggesting it is very likely it will work because how close they are .... small chance it wont work .... in 1 hour or so you can find out. No idea why you want to change them. 4.1 is what my truck has, great around the town or farm, 50mph probably top speed stretching it. Good for a race car in a 1/4 mile track. The 3.9 is better for highway use .... maybe 60 mph? .... I dunno but more highway friendly then a 4.1. 1 Quote Link to comment Share on other sites More sharing options...
Crisjr14 Posted March 17, 2023 Author Report Share Posted March 17, 2023 Los Control thank you for the info I should be more specific the 53 that I want to change the rear end only has the flat 6 in it and also the leaf springs are messed up as well as leaking oil and I'm getting ready to get rid of the 54 I bought for parts and just want to see if the rearend would be good to save for later issues I come across Quote Link to comment Share on other sites More sharing options...
Booger Posted March 17, 2023 Report Share Posted March 17, 2023 absolutely save anything you can Quote Link to comment Share on other sites More sharing options...
Los_Control Posted March 17, 2023 Report Share Posted March 17, 2023 How much storage space do you have? ??? If the brake drums are any good you want to save those, any decent hardware, springs, shoes. Good chance the axles will interchange if the rear ends are same width. The drums for new replacements are $400 each .... Springs and brake hardware are kinda unique .... you can order online new ones at a premium price. .... Never know when you need a axle. Too be honest with you, depending what your end goal is ..... When my rear end gives me issues, I'm going to replace it with either a jeep cherokee or ford explorer rear end. I want 3:73 gears for highway, I will have modern brakes I can buy at any local parts store, I will change the u-joints & drive line to fit. My current u-joints on my truck are hard to find & $80 each. I'm just saying, if the hogs head was bad on my truck I would not mess with installing another just like it, I would swap the complete rear end. So I would not bother storing it. Good brake drums ... yes ... small hardware, springs & shoes ... yes. A axle .... maybe. The leaf springs throw me off. .... They generally are vehicle specific. If they are bad on your car you want to build .... I have no idea if the ones from your parts car will fit. There is a really good chance they can help you repair yours ..... if you take both spring packs apart and assemble with good springs ... no idea if they just bolt on. I would save those if yours are a issue. Quote Link to comment Share on other sites More sharing options...
Loren Posted March 18, 2023 Report Share Posted March 18, 2023 Here we have lots of opinions all have some merit. I personally favor keeping the stock rear end. Its a good design and changing it won’t give you more power or reliability. I just saw a fellow asking for help figuring out what kind of brakes his car had because no one told him when he bought it. On axle ratios if you are going to drive highway speeds you’ll want the lowest numerical ratio. The lowest numerical ratio in the stock rear axle is 3.54 ( I have heard of a 3.23 but have never seen one ). The 4.1 ratio you have usually came in cars with an Overdrive transmission. That is a super desirable item so take a real good look at that car. Overdrive with a 3.73 is a real good combination. If anyone is looking for a 3.54, French Lake has one in a 56 DeSoto on ebay. You might ask if they have an Overdrive as the last one I bought from them was $250 plus $95 shipping. Anyway that’s what I’d be doing. Overdrive transmissions should be left in gear out of Overdrive when parked and the parking brake kept in good condition. I found a solution to the iffy parking brake issue. Speedway Motors has a special valve that gives you 4 wheel parking brakes. You push down on the brake pedal and pull on a knob that holds the brake pressure.

Crisjr14 Posted March 18, 2023 Author Report Share Posted March 18, 2023 Thank you Loren but I am a little confused everyone is saying that the 3.9 I have in my 53 daily driver that has a flat 6 vs the 54 I bought for parts which the emblem on the hood looks like it says v8 so that would mean more power on freeway but comments are saying that the 4.0 would be slower on highways vs my flat 6 with the 3.9?

Shipping is insane on that, pretty sure it is the entire axle, not just the center section though. Quote Link to comment Share on other sites More sharing options...
Loren Posted March 19, 2023 Report Share Posted March 19, 2023 Yes it is the whole thing. I don’t need one so I didn’t investigate further but one could ask if they could ( for a fee of course ) send you just the differential carrier. They seem to want to work with their customers. I spotted a rare 6 volt positive ground Delta Mark Ten CDI in a photo and inquired about it. They set up a buy-it-now auction and emailed me when it went live so I could buy it and not violate ebay rules. A carrier should weigh about what an O.D. Transmission does and the shipping for me was only $95. Bottomline, stuff is out there if people will look for it. What I have seen is crazy ads for odd parts, yet they show you the whole car from several views. The idea being to start a dialog with buyers so they will inquire about other parts.

Booger Posted March 20, 2023 Report Share Posted March 20, 2023 (edited) I cant find anything on years/model 10 bolt pumpkin vs 11 bolt. I suspect 53 on up Anyone? Edited March 20, 2023 by Booger spel Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted March 21, 2023 Report Share Posted March 21, 2023 The 1953 Dodge six cylinder car would use 16 spline axle shafts in a 11 bolt carrier. 1952 and back cars use 10 splIne axle shafts excepth for Crown Imperial Chryslers. 1 Quote Link to comment Share on other sites More sharing options...

I bet if you looked up the carrier gasket in the parts book you'd know what had the same bolt count. Carrier itself changes tween 1950 and 1951. The gasket is the same 1941-1954 1 Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted March 21, 2023 Report Share Posted March 21, 2023 Eight cylinder cars,long wheel base 8 passenger and station wagon six cylinder cars except Plymouth use 10 bolt carriers through 1952. 8-3/4" ring and pinion. Quote Link to comment Share on other sites More sharing options...
D35 Torpedo Posted April 17, 2023 Report Share Posted April 17, 2023 I'm bringing this thread back because I'm researching axles. My 50 dodge has 373s and a driveshaft with universals. The 52 plymouth has what I believe is 39x and an 11 bolt pumpkin with a trunnion driveshaft. I wasn't able to find stampings like the samples found online. Below the plug it says 039 8760. They look almost cast in, not stamped. Anyways, in order to run universals, are the flanges different? What models have the parts? Any other info to add would be appreciated.
