Default Ford 8.8

Hello,
I just picked up a Ford 8.8 out of an 89 lincoln Lsc. Going to use in my next project. Disc brake, good ratio, inexpensive.
Question: should there be some play or runby in the differential? If i turn the pinion, im getting a bit of a "click" right now i am just cleaning this rear up, stripping it down, prep work. Looked at oil, its dark , but looks normal.
Thanks for weighing in
Russ

If it clicks when you rock the pinion back and forth, you have excessive backlash.

If it clicks when you rotate the differential... bearing(s).
