There's a large plastic covered wing nut holding the jack on both my 2001 Yukon (under the 2nd row bench seat) and my 2012 Yukon (over driver's side rear wheel well compartment). Maybe yours was misplaced and replaced with a 3/8" nut

That’s just the bracket for holding jack securely in truck. Iirc you turn the yellow handle to lower the jack to remove it from said bracket buddy.Can’t remember if it’s a 8 or 10mm nut. It’s easier to see on the 09 white truck vs the past 08 black one. There’s three of the little suckers.
It could be a 07-09 thing. It is a factory job as the nuts and threads are painted over. The wing nuts pictured below are what the nuts were replaced with.
Once the large plastic nut is removed you’ll see the surprise GM gave us.

And this wasn’t put away correctly. Yellow nob should face up, chocks go on the side and again you just lower the jack and it pops out of bracket with wheel chocks.. budHere’s what it looks like when you’re undoing those two plastic nuts being referred to access the lug wrench. If you’re unlucky you’ll pull the tire down, loosen the lugs on the flat tire and then discover the bottle jack is bolted in when you go to pull it out.

It is, it’s like a friction fit. Up to hold it in, down to remove it. The yellow knob is actually stamped with words/arrows for up and down zzzSomehow I was thinking that was a shipping holder/support and not part of the jack, but I can't see it clearly enough. The jack looks partially extended/raised in both pictures.
Although now I'm wondering why the hole is in the bracket for the shaft to go through. If it was just a recess, the jack could be raised/extended enough to be a tight fit against it.
Not really. Started to strip when that size was used. Hence the question. All good now though. Impact 22mm works well.7/8" converts to 22.2 mm. Should fit nicely.
