How do you tell the difference between D60 and D61

[koonsdawg]

I am looking at buying an 1990 1 ton Dodge. I want the axles off of it. And I was told that that year came with either the Dana 60 or what's called the Dana 61. I was also told the D61 is no good, so how do I tell the difference? They both look the same to me.
Thanks,
Brandon

It is cast into the webbing on the center section. It will say 61 on the web. Or if it has really high gears.

They came with 61's too, for the higher gears. For what it's worth, you can buy a shim for a 61, to use 60 gears. That is why people don't like 61's. They have a different case offset than 60's.

I found this page on the Dana 60's. Just about anything you would want to know about them. DANA 60
Thanks Guys

Well I couldn't find anything in the webbing of the axle. But I did get the number off of the back. These are teh gears I'm assuming it said 43-14 307. I'm assuming that means it has 3.07 gears. So does that mean that the front is the Dana 61 because of the high gears?

Yep, it's a 61. 43 teeth on the ring, 14 on the pinion. 43/14 = 3.071428

Well that is good to know, now I need to try and find some more axles. Back to the drawing board.

There have been people running a shim in 61's so they can run dana 60 gears... search on pirate under SanDiego CJ's name.

I bet it's still worth getting if you get the right deal. If you pass on it, let me know.

FWIW, I am running a 61 in the rear of my 4runner, I installed 5.86 gears with 35 spline mosers and welded the diff. You have to get a certain carrier for the 61(I believe it was a 4.10 and higher(numerically lower)ratio and add a shim to it, Randy's R&P carries it, its steel and costs about 45 bucks.) I installed disc brakes on it also for about $150 bucks, it measures 67" wide, its a FF.
