1948 Dodge rear end id

[Bradk2588]

Hi guys I'm hoping that someone can help out a bit in figuring out what rear end this is. I dont know much about it or the truck other than it runs and is fun to drive lol.

[Bradk2588]

 

go

 

got a few other pics that may or may not help 

the only thing i can find on the housing is a R6885 on driver side and a DC18B

show a picture of the pinion side...I would guess by size of the vehicle and year this is an Eaton two speed but again, that would be just a guess 

[Bradk2588]

it isnt a 2 speed

[Plymouthy Adams]

obviously it is not given the newly posted picture.....at least is now ruled out....to bad the casting number is such a mess...thanks for taking the time to post this view...

[Bradk2588]

LOL Ive been scrubbing it with a small wire brush to try an find something But axles and what not are not for me lol

[Plymouthy Adams]

one on a 49 on e-bay still in the truck out of Louisiana…..maybe a note to him will get a part number you can identify...

[Dodgeb4ya]

That's a typical Dodge manufactured standard single speed rear axle housing and differential. 

Ratio could be eithet a 5.6,  6.2 or 6.8 

That number is stamped on the driver's side (left) on the differential case.

 Look for it on the bolt mounting flange ...1/2 way up.

not with that "stepped" cover it isn't.  the eaton 1350 has a "smooth dish".

[Plymouthy Adams]

 by not knowing that rear feature you point out by asking for the picture of the front as it would then be known if or in not a two speed........which was an effective question as the picture was quickly posted...,,to help in the future maybe you could post a pic of the Eaton 1350 two speed...

Ok thank you!!! The ratio stamped is R 6885 

 

Now for the other part. Is that a rear end that I can just change the rear brake housing and hub and of course the brake to update to an 8 or 10 lug?

Not much you can do with it...

But new brake reline and play country farmer with it.

Not much interchanges as for ring and pinions....no nos parts easily available

Enjoy what you have or tear it all out and start from scratch to build what you want.

visual aid

[wallytoo]

eaton 1350 2-speed.  note that the air line and diaphragm are visible from the rear, another thing clearly not in the OP's image.  don't confuse the midland brake booster with the vacuum shift diaphragm.  booster is "centered", the diaphragm is partly visible at the upper left of the differential.

 

 

 

[Plymouthy Adams]

thanks for the pictures...was not sure how well one could see the vacuum control for the two speed, I admit I have only seen one in the last 15 years and that was just a glance and not looking close, I am sure this will help others (if they take the time to search the forum correctly)

can't help you with what might interchange.

 

your truck is equipped with the auxilliary side sills to beef up the frame.

[Bradk2588]

I seen that it was pretty beefy and what not Nice pto setup Just needs some updating lol I plan to make it my hauling truck and using the body make 48 pick up truck

Just havent ever messed with something this old
