Highly doubt it, it broke at 1ft of force, i have a feeling someone put a ****** gasket and ****** bolts.

Hopefully i can get it out myself easy enough without having to drop tranny to then drop oil pan lol…
Yeah no doubt someone has played with it,maybe Ill buy new bolts when I do mine.

If I couldn't get it loose with the sledge I was going to use the air hammer, but it was late and would've waited till today to do it. That thing's loud.


Can't, these are the alignment cam bolts that are flat along one edge and can only turn so far due to the pin sticking through the slot in the plate

EDIT: Oops, thought you were talking about my upper control arm bolt. My bad :chewie:
Yeah, you have bigger problems.

Welp, got the driveshaft detached and moved slightly out of the way for extra room.
The bolt inside the oil block off is busted inside, nothing sticking out.

The bolts are M6.

Guess it's time to order angle drill and extractor set small enough to try and break the M6 bolt out.
Otherwise i'll have to drill the hole bigger and put a helicoil or something, any ideas welcome!

Don't have a welder unfortunately, seems like welding a nut there would've been ideal

P.S Looked around and if i break it for good, i'll have to remove transfer case to get the oil pan out, so much fun lol

The holes in the block are weak as well because the block is aluminum, so they will barely hold the specified torque. I'm surprised anyone got that bolt tight enough to break, frankly. I had to use a helicoil in my 2012. Best bet is an EZ-out to get the bolt out but gotta watch that the drill bit stays in the steel bolt, otherwise it's gonna be a mess real quick.

I'd think the easiest would be to find a friend that has a welder you could borrow and weld a nut to it, or go buy a low cost ($150) one from Harbor Freight. It may come in handy in the furure

Well I screwed up yesterday morning.

I usually back into the driveway but when coming back from taking my daughter to school I pulled in due to it being trash day and I had my cans at the end of the driveway on the left and my neighbor had his on the right between our driveways and it was just easier (I had 3 containers and neighbor had 3, trash, recycles, yard waste).

A bit later when I went to leave for work the trash truck was there emptying the cans so I sat there for a minute or two waiting while watching in the rear view mirror. The wife's Acadia was parked behind me to my left and I actually forgot that she was off work (she's usually already at work) so when backing up I started to move to the middle of the driveway to avoid the trash cans and hit the Acadia.

The Yukon's driver rear panel just behind wheel well.....

Acadia passenger rear at same area....

It's mostly just paint damage, but there is a small golf ball sized dent on both vehicles. Right behind the wheel well on the Yukon and right on the wheel well lip on the Acadia.
You can try a damp magic eraser with light pressure to get rid of the paint scuffs

I've done this many times on aluminum boat components. Take a dremel tool with one of the small cut off wheels and reach up there and grind a slot in the end of the broken off bolt for a flat tip screw driver. You mentioned the bolt wasn't tight when it broke off so it should turn right out. You may end up cutting a bit of a slot in the aluminum too but that won't hurt anything. Good luck!
