Dana 44 Pinion and Carrier Installation (True Spirit #18) 

It doesn't matter. They should be turned 90 degrees from one another, so one will look like an N and the other a Z

No, this is correct. The Dana 44 is a little odd, but the easy way to tell is that the seal lip has a tension spring around it. That spring goes inside the differential when assembled.

@@YoshimoshiGarage Correct,spring allways goes toward lube side!

I've always assumed they were 3.54, now I need to either look at the video or go pull the cover back off.

I was going to pretend I counted the teeth during the video, but we all know I'm too lazy for that. At about 8 seconds in, you can see the pinion is stamped "47 12" which is a legit tooth count for the ring and pinion in a Dana 44.

Thankfully the Dana 44 didn't start using a crush sleeve until much later than this axle (I don't know what year, but definitely after this 1978). Preload on this one is set with shims.

@@YoshimoshiGarage thanks for info. End thanks for the video.👍
