Hmmmm…...if you turn the driveshaft, how much before the wheels move? Have you verified that the u-joints, tailshaft bearing/seal and rear end pinion seal/bearing are in good shape? No movement when wiggled firmly side-to-side?

4 or 5 inches could be the spider gears turning before the driveshaft moves on a open rear. Leave one wheel on the ground and try it. Or have someone hold the opposite wheel. Normally only one side will work at a time when jacked up.

The thread title here is misleading.

When you had it out, did you turn the yoke and watch the ring gear? If so, how much did the yoke turn before the ring gear moved?

I would take a look at the cross shaft in the ring gear carrier.....the shaft that the spiders run on and make sure the shaft itself is good in the carrier. Never seen one waller out the fit in the carrier on an 8 3/4 but have heard of it but had one with a 9 1/4 that got bad enough to where it raised hell one time when going down a slight hill with light throttle.
