Visually Identify Dana 44 Carriers (carrier break)

Visually Identify Dana 44 Carriers (carrier break)
There are two different carriers on a Dana 44. The carrier break on a Dana 44 is 3.73 down and 3.92 up. So if you're looking at a dana 44 open carrier how do you know what one it is? Here is a simple way without having to do a bunch of research.

The carrier on the left is a 3.92 and up. The carrier on the right is a 3.73 and down.

The difference is the rings gear mounting flange. The 3.92 and up flange is about a 1/4" closer to the center of the carrier than the 3.73 and down carrier. If you don't have the both of them sitting right in front you'll want to look at the raised lip that the ring gear uses to center it's self on the mounting flange. If you look at the photo, the 3.92 and up is about half the size. This is a good visual reference to use.

   

The reason I'm pointing this out is because I payed for a a 3.92 and up carrier and I was sent a 3.73 and down carrier. If I didn't do some searching on the net I wouldn't have found out this was a problem until I went to go install my gears. So I'm posting the information here just for reference.

Yessir, its something to look out for.

Standing up like you have shown, a 3.73 & down carrier will measure about 2" (2.090") from the table to the ring gear mounting surface.

A 3.92 & up will be just over 2⅜" (2.410").

Its a quick way to check with a tape measure when out shopping for used parts.

This reminds me that I need to snag a 3.73+ carrier for my dana 30 from the junkyard.

Dana 30:

3.54 & down is 1.800"
3.73 & up is 1.938"

Or you can run "thick" gears on your carrier. Meaning the ring gear is thicker than normal to account for the extra space.

This is what I was just about to post. I needed an open carrier for a lunch box locker. I'm cutting costs to make sure I get this done in time. The carrier in the D44 I have has a factory limit slip in it. You can't put a lunch box locket in those carriers.

I didn't realize anyone made thick gears for a dana 30.

The odds of me ever regearing this thing are between slim and none anyway. But, hey, if I have the carrier .... maybe some day!

Correct, they will only fit in an open carrier. You can shim a limited slip to act more like a spool, which is fine for the street, mud, or trails. But it wont live long in the rocks. Another low dollar option is to weld the spiders, great for rocks or the trail, but takes some getting used to on the street.

Are you going to lock the rear differential too or just go for front?

Matt tightened up my limited slip last year and it was great for half the wheeling season then it was toast. I know when we open it up to install the spool the clutches are going to be shot.

Both. I have an ARB for the rear.
