Loud 'Thud' After Turning My Wrangler Off

This has happened a couple times I can recall recently, will be paying closer attention to see if it's happening every time I turn my jk off.

Anyway, it happened the other day at home and I remember not being sure if it came from my jk or not, so I just ignored it - shes driving fine as far as I can tel - no odd noises or feelings while crusing. However, pulled into the garage at work today per usual, backed in etc etc as always and while putting on my dress shirt I heard it again (try to cruise with the top down and no dress shirt on when I can ). It is just a really loud *THUD* sound, couldn't tell exactly where it came from but I don't think it was all the way in the front, which leads me to believe it isn't the engine or anything else up there. Something down belowe closer to the middle I think.

Has anyone else experienced this or know enough about cars/jeeps to give a good educated guess as to what it could be?

My JKU is manual by the way, and when I first got it a few months ago I wasn't too great at driving standard, although definitely have the hang of it now and have for a little while. I find it hard to believe I could have messed up something in that amount of time but I can't think of anything else. It's a 2010 with only 11k miles so it's in pretty dang good shape, at least I thought it was.

Thanks!

I was already stopped, parking brake on, in neutral, key out of the ignition, and out of the jeep.

There is a vent/door behind the glovebox that opens/closes when you turn the jeep off. Maybe something's up with that ?

Do you shut it down in gear with the clutch pedal depressed? Your throwout bearing could be binding on the shaft and it then suddenly releases after it sits for a bit. Doesn't do it when it's running because the shaft is turning.

You could try pressing the pedal in all the way, then slide your foot off of it (let it snap back on it's own, don't release it like you would when shifting it). See if it is the same/similar sound.

Just a guess.
