Lug nut wrench size?

[gooffeyguy]

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

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.

Here’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.

Must be an 07-09 thing

Or just an Esky thing. Actually surprised an Esky comes with a jack and spare. Ballers that drive those just call for roadside assistance

Seriously though, sometimes we just use the foam kit to re inflate the flats when there’s no spare

Different generation, I know, but mine doesn't look anything like that. But again, you're making me think I really need to pull mine apart and make sure I know how it all works. I hope never to need it along a roadside, but if I do, that really isn't the best time and place to do it for the first time.

On the subject of lug wrenches/4 ways/breaker bars etc I bought a cheap collapsible 4way probably 20-25 years ago… it’s still in one of my cars somewhere but this thing busted loose 32 lugs on my 89 3/4ton w250 dodge plow truck 16-17 years ago …steel rims and straight lug nuts, no chrome bs caps. I couldn’t bring myself to throw it out when I cleaned my garage to move. Folds down for easy storage…. Lol

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.

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.. bud

Somehow 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.
