Last night I saw fluid under the rear of my 2021 UForce 1000.  There is a small puddle of fluid on floor of my shed and it is dripping from the protective underside of the machine near one of the holes around the rear differential.  The color of the fluid is bluish.  I have read something about bad O-rings on the drain plugs, I haven't had a chance to really identify where the fluid was coming from.  Hoping to get a chance when I get out of work today.  Anyone else ever have leaks near/around the rear differential?  Even thought the buggy is 3yrs old, there are very few hours on it as I don't really drive it that often.

Step 1 would be to ID what type of fluid it is. Blue or bluish isn't a normal color for gear lube..but also isn't for coolant either...at least not around here. Could something have leaked in the bed and dripped down?

OK, the leak is coming from the differential drain.  It was wet all around the allen screw drain plug.  Color of the fluid isn't blue/bluish, it just looked that way because of the rubber mat I have on my shed floor.  On my fingers it was basically clear.  I didn't try to tighten the allen drain plug, but will try that in the morning.  I want to confirm that it is still an active leak before I try and tighten the plug.  Thank you.

Remember...it shouldn't take that much. Over-tightening causes stripping. When I do mine I always use some Teflon pipe dope or anti-seize and just a good snug. I use the same washer just gets cleaned-up.
