I'm new here, so hello everyone....I just bought this truck, 1988 Dodge Power Ram 150... almost rust free except for the bottom 2 inch of front fenders... But the transfer case is cheewed up and the rear end is different that the original. How do I find out that gtear rear end I need to put in this truck so I can replace the transfer case? Like I said, its a 1988 Dodge Power Ram 150 318 Throdal Body injection. I found no build number plates under the hood.... no stickers in the doors... all I have is a vin number, is that enough to tell me?

I am memeber on ramchargercentral.com and they have a vin decoder that may be helpful for you.

 

thanks, but i wnet there and it told me just the year.... type, and where it was made.... do you know by any chance what was the most common gear ratio for these trucks?

 

I know in mine and I have a 1984 Ramcharger 150, that it has a d44 and I think other is a 9.25 by chrysler. I am pretty sure mine is 3.23 for the gear ratio or something close. I would have to say it would be pretty similar set up. Have you tried posting on there they are super knowledgable people.

 

You can request a build sheet from Dodge via this link: http://www-5.dodge.com/wccsapp/unive...ull&category=R

Not sure if it will work with older trucks, but you can give it a shot. Good luck!

 

Thanks Burning Rom.... Hopefully that works, so I can start fixing this truck and start having some fun.

 

well.... my front diff. cover has this stamped on it:
DANA
41545
033 0
REV RP
12 22 83

 

ok.... i counted the teath and here is what i got.... Big gear - Pinion gear??? is 46 and the small gear - RIng gear? is 13.... does anyone know how to calculate it?

 

Big gear is the ring gear

And 46/Ring 13/Pinion would be a ratio of 3.54/3.55

 

Check under the front seat inside the cushion area for a sheet.
FYI-Both the front end and rear end need to be the same ratio.

All of this info is for the cover only...41545 is the DANA part number for the cover,
DANA
41545
033 0
REV RP
12 22 83

If you want to find out the real skinny on what axle asm you have...you have to locate the BOM (Bill Of Material) number that is usually stamped on one of the tubes on the axle assembly. Might be something like 610277-1 or 610329-2.
