https://www.amazon.com/photos/shared/udHGWW8ZSVajyiyY8sfpzQ.8YD2xielXLNjBf4f1VXnc3I was driving home today at around 60 mph and I was speeding
up a little going ever a hill and I heard a loud rattling noise
let off the gas and it was gone, accelerated again and it came
back, accelerated again noise was gone, I pulled over and
checked it out and saw the ac compressor wheel nut had spun
loose and was still there layin in the pan below the ac compressor
pulley unit. Stopped by the local shop had the mechanic retighten
the wheel nut and turns out my water pump leaking too,
he said he got the wheel nut back on really tight but on
my way home the very same thing happen this is really weird.

I dont have the two prong tool to put back on tight.
whats next?
I wonder If it be ok to drive short distance with out the wheel nut on?

This is the wheel lock nut for the ac compresser that spun off

That's really odd. Check the threads yo see if they are damaged. If they are fine then Macgyver up some tool and throw thread locker on it to keep it in place.

I'd also check it while the car is running to see if you can see anything wobbling when it is reinstalled.

I'm not entirely sure of that parts purpose as I'm sure the pulley is bolted on?

The photo didn't work but instead of tightening it lots, use thread locker compound on the threads when you put it back on. That will help it from coming loose. e.g. https://amzn.to/2H6igpj

Yep the treads are fine and I cant see any woppling with the
car idling

It's actually a damper and it happened to mine while under warranty. I asked the dealer to reinstall it with thread locker but they insisted on replacing the complete compressor at no charge.

If it happens again I agree with previous replies and would just use thread locker.

had this happen twice in my 09

I wonder if a special circumstance that causes this to happen? Like over speeding the compressor by down shifting 2 gears.
