15HU differential input shaft play
Dear gents,
A few months ago I substituted my old diff due to play in the input shaft (MY 2000 XJR, approx 140k mls on car & old diff).
Having the old differential now sitting on the shelf, I'm wondering what kind of work is involved to get rid of this issue, so that it'll serve as a intact spare one day.
The diff is clean and tight. The oil had been replaced last year - oil level still good. No oil leaks - neither before nor after the oil change. Vent mechanism is clean and free. No squeal, no noise, no other play than in the input shaft.
When turning the input flange back and forth the play can be felt. It's no axial involved but approx 1-2 degrees of rotational play .
Any ideas, approaches or experiences on how to find out what's wrong and how to cure the issue?
I'm quite familiar with turning the wrenches at our Jags, but I never had anything to do with differentials. I do know that there's sometimes fitting components under preload conditions involved, but that's a closed book yet. Nothing that I'm not willing to learn but there's only little prior knowledge to differentials.
Thanks in advance and best regards, Alexander

I attach a few documents that I gathered before doing work on my BMW E30 M3 differential and also documents on Dana diffs (I had a Daimler Double Six in the past).
