Dana 44

I bought a 76' CJ5, very modified. The rear axle is out, spicer gear according to pics, and I am not familiar with axles. Everything I have seen online says it is a Dana 44. The stock axle should be an AMC 20. There are no marks or numbers to ID what kind of it really is. Are there any websites that give lengths and deminsions of axles to help me ID this? What do I do to ensure that I purchase the correct ratio? Is the front ratio also a consideration?

Does it look like a misdrawn stop sign? ...Dana 44

If it looks circular (not oval) ..AMC 20

Re: Dana 44

I am almost certain it is, based off of 2 websites that I found. I just want to be more certain on the year/type of Jeep it came off of, I am leaning toward a 75' or earlier. I am not sure of the difference between a tapered axle or a flanged axle, or the importance the gears ratios play between the front, rear, and t-case.
Thanks for the help.

Re: Dana 44

Tapered vs flanged axle refers to the flange on the end of the axle, which the wheel studs are attached to. Early dana 44's and all CJ AMC20's used a tapered axle, to which the flange was pressed on and retained by a large nut in the centre. This nut is visible beneath the hub cap, if any. This tapered design generates a weakness in that the flange can spin on the axle and strip the spines at the outer end. Newer dana 44's and heavy duty 20's used a one piece axle that is stronger, as the flange is part of the axle itself.

Re: Dana 44

actually there are no outer spines on the tapered shaft 44, there is a shear key. they also require a special puller for the drum and a slide hammer to pull the shaft.

Re: Dana 44

i forget the percentage of the gears.. but if you have a 4:09 in the front.. and the rear is 4:11... they are esentially the same.. 4:10's is the common name for those..
