1970 CJ5 rear axle shaft

I have a 1970 cj5 with a v6 and have a bent hub in the rear. I have been told I can upgrade the rear hub assembly to a one piece shaft and hub. Is this true and what do I need to buy? Thanks

You need to find a rear axle out of a late 70 or 71 CJ.
Offset Dana 44 with 30 spline 1 piece shafts.

Will the AMC 20 one piece shaft assembly not work? I'm trying to not have to buy a new axle.

No, it's a completely different axle. The diameter and spline count (your D44=19 spline, AMC20=29spline) where they engage the spider gears inside are different just for starters.

You don't have to buy a complete new axle assembly either. Just get a replacement for the two piece axleshaft. The Dana 44 two piece rear axle is much stronger than the AMC 20 and isn't nearly as prone to failure.

If there is anyone out there still making a one piece replacement for the D44, I can't find them. Moser or Dutchman may be able to custom make one for you.

Omix is saying they make one for a 1972-75 which are Dana 44. Shouldn't that fit?

Best bet on fit would be to talk to supplier. If they have a tech line, use it. Then you have straight answers from them.

Good luck.

There's a reason why it says 72-75 and not any other range of years. No it will not fit. Your axleshafts are a different spline count (19 as said already) and your differential sits right next to the passenger side leaf spring. On the 72-75 the diff is pretty much centered between the springs and uses a 30 spline axleshaft.
