My brother warped the front diff carrier on his 68 CJ-5when he broke a ring gear tooth. Apparently the broken tooth got caught between the ring and pinion and warped the open diff case. So it happens. You might check the ring gear bolt size on your old carrier and any new one you intend to use. Dana went from 3/8 to 7/16" bolts on 44's in recent years. Foggybottombob mentions the JK 44. As I understand, the rear of those are a totally different axle and should have been renamed--bigger ring gear, bigger pinon shaft among the differences.
