Play in the final drives on Super AI

[customcutter]

I was unloading the new to me Super AI yesterday and when I was pushing against the rear tires, I noticed some side play in the final drives. Not sure but I think it is on both sides. I haven't inspected/changed the fluids yet, but wondering if this is a slight problem or a large problem?

I checked for side play on the Super AV and everything is tight no play at all. I was doing research tonight, and most of what I have found is related to Cubs. One thread on Super A's indicated it's somewhat normal?
