Club Car Leaking Oil from Rear End

[RJ95]

I have a [90's?] Club Car DS electric golf cart that until recently has ran great. I noticed it was dripping oil when it was parked and sometimes left a trail the last time I used it. I jacked the rear end up to look and it looks like it's leaking from a small hole on the passenger side. Am I missing a bolt or did I crack it somehow? I am mechanically inclined but very unfamiliar with electric golf carts, I would appreciate any advice

I'm pretty sure that's the fill hole for the oil and it should be threaded. There should be a short bolt in it with a gasket/washer. Welcome to the forum.
