Rear axle noise

My 98 Sahara rear axles is making some noises like grinding I think. Its a d35. It happens when driving and down shifting. I jacked it up and I think that my driveshaft is the problem. It looks like its moving way to much and far out of the pinion. I checked the wheel bearings and all is good there. Any ideas. I'll post a video of the drive shaft.

Been studying up to rebuild a Dana 60 rear end in my pickup- there is no way the pinion should be moving axially like that. The preload on the pinion nut is supposed to lock the axial position between the bearings and shims to control the pinion gear mesh with the ring gear. The only thing that comes to my mind is the pinion nut loosened. (When you down shift the pinion goes from driving the ring gear to being momentarily driven by the ring gear (loading the gear teeth on the opposite side))

I checked the nut and it was a little loose. But not bad. Noise is still there. I don't plan on doing that much wheeling with it so now I'm looking for a d35. Can't find one anywhere here.

It could be the pinion bearing going bad. I just had mine let go today. The pinion had up and down movement. You don't want to tighten the nut as that will change the pre load. May want to take the cover off. I did yesterday and after what I saw I am glad I wasn't on the freeway when she blew. I shouldn't have even driven it. Oh well.
