What's in my Jeep?

Hey guys I need help figuring out what axles are on my Jeep. Is there any way I can find out? I think the front and back are Dana 44 but I don't know for sure.

If there is still an AMC 20 in the rear, chances are very good that the stock D30 resides in the front. The D44 was never offered as a stock front axle in a CJ to my knowledge, and most swaps to get a 44 use a Waggy 44 which requires out-boarding the front springs. You can make a D44 with similar axle tube lengths to a D30 but it is a lot of work.

Check for a number casting on the axle web like shown here:

Don't discount the model 20. With good axles and maybe a truss it's carrier strength rivals that of a 9-inch ford with the axle tubes being the weak link. Add a truss and it's bullet proof. I have run one for over 15 years with Moser one piece axles and it's been reliable and much cheaper than building/buying a d44.

Yeah but were you running the axle with a stroked 327 under the hood? That much torque and power can easily snap that thing. Probably cheaper to get a dana44

I don't have a stroked 327 under the hood. I have an AMC 360 with 11:1 pistons and a Howell fuel injection system. The trans is a modded 727 with a D300 trans case with a terra-low 4:1 kit in it. For gears I have 3.54's for highway driving with the reduction in the transfer case and the torque from the 360 it goes wherever I ask it to. It has been all over Disney OK and the other spots within driving distance from where I live. Good luck with the d44 though. Just hoping my two cents might help you save a bit for the next project as these old Jeeps always need something else! Best of luck.
