CJ7 slack in the rear diff

I'd like some advice on diagnosing slack in the rear differential of my 1985 CJ7 with the stock AMC 20 and 2.73 gearing. When moving through the gears, the driveline very noticeably clunks as the torque on it changes. When parked, I can grasp the rear driveshaft and turn it; there is about an inch of play. I was wondering if anybody could guess what was worn out (ring/pinion, differential, axles...). There is a locker in the rear and one-piece axles, but I don't know any details on these mods as they were done by previous owners.

The ring and pinion may be worn a bit, but you are describing the normal behavior of a locker. Practice your shifting or remove the locker. Double check that the u-joints are not worn out.
