Dana 44?

Most dana 44's have a 5 on 5" bolt pattern.
Nobody in their right mind would spend the money to change bolt pattern to a mopar 5 on 4.5".
A 44 is a marginal rear and a decent front in a CJ.
I broke 7 dana 44's in one month in my first CJ, it was so bad I kept a built one for a spare.
The best one I broke, I twisted the axle tubes out of the center.
40" tires on a cj-5 is hard on parts.
