Reminds me of the story my 4 older siblings told me about the time my dad finally agreed to take them kite flying back in the early 70's. My brother had been pestering my dad to take them and when finally agreed and took them out to my uncles pasture, he was so excited that he slammed the back door of the car and since the window was only part way up, it ended up in pieces all across the back seat. My dad was pissed and promptly swept most of the glass off the backseat and onto the floor board and told the 4 of them to get back in the car and took them home.
Yep…my grandad had an old ford pickup that we used for delivering sod from the farm. We had just gotten stuck 50 rolls of sod @ 50lbs in each truck driving across wet peat moss soil. Getting stuck happened daily, but this day my uncle was in a bad mood. Must have been up late drinking or something. After sticking his head out the window to looking back and yelling something at me, he got out of the truck to hook up a tow strap to the truck my fourteen year old self was driving (mind you I can hardly drive a stick at this point because I could barely touch the pedals, let alone see over the steering wheel at the same time). Being in one of his moods he slams the door - forgetting the window was rolled down - and pieces of it landed in the seat. Guess who had to clean his mess up?

I wouldn't even have a chance to open the doors for them. As soon as I put it in park and the doors unlock they're already out of the vehicle. I haven't even shut it off yet, and usually still grabbing my glasses or something off the console. Don't know what the hurry is these kids have.
Child safety locks. Except maybe then it will be interior door handles they break. Dang kids, you can’t have anything nice with them around.
Going to install a new front driveshaft. The trainwreck of a previous U-joint replacement and balance of both shafts by a local franchise left me with the welcomed decision to cut my losses and have the Driveshaft Shop build be a new shaft.

I tried to source a new OEM shaft but kept coming up empty, I feel for the long hail this is the better option.

I'll get a side by side pic later. I'm very impressed with the build quality of this.
Which company did you go with for the new one?

was behind a clean yukon denali xl in that kinda rare gray color this morning in a drive thru. thing was very clean and I've always liked that color. I didn't realize he had it shut off to order, when it fired it up definitely had some louder than stock exhaust and you could hear the text book miss, and then the valve train tap.

probably just out driving it till it stops and ends up in a junkyard. such a shame what gm did with these engines. if I didn't have way to many cars and projects I'd have been tempted to ask if he wanted to sell it for cheap to save it.
What gray color are you referring to?

My kiddo used to slam the door every time. When I used to drop her off at high school I told her that if she slammed the door I would honk the horn and everyone would look. Only happened twice. Behavior modified successfully.
That’s perfect. Similar to using an e-collar to reinforce positive behavior with my dogs. It has to be a double honk though, almost like an auditory “honk you!” to whomever slams the door.

My daughter used to do it 5-6 years ago after we first got the vehicle, but I told her not to because it could break after a while and showed her how to correctly use it.

Not technically kids anymore though. My son is 23 and his girlfriend just turned 21, but she acts more like my daughter whose 14 now. She's from out of state and still in college, so she's really not around here much.

well that's one way to beat the rust, lol

I don't know why I didn't just zip them off with a carbide blade in the first place. I've been soaking the nuts in PB Blaster multiple times a day all week, and they won't budge. I was about to break out the torch and then my brain went, "hey dummy, cut them in half."

Looks like I'm going to have the parts to rebuild the rear diff in the '12 XL Denali (8.6")

If anyone has the torque specs handy, I'm looking for the rotating torque for both pinion and carrier with new bearings.

What I have is:

65 foot pounds for ring gear
60 foot pounds for carrier bearing cap
14-19 inch pounds rotating for new pinion bearing.

Once the carrier shims are snug I will start with .004 on each side additional for preload then check

I believe it's 20-25 inch pounds for the carrier but not sure, which would equate to an additional 5.8-7.3 inch pounds to the pinion rotating torque with a 3:42 axle ratio.

I want to say @swathdiver might have this info.

Anyone feel free to chime in.
Don't know if I'm late to the party...

Wife took it to an "Event" today for work. Actually an Annie Malone back to school event.

We removed the 3rd row and folded down middle row, loaded up a 10x10 pop-up, folding table, a couple chairs, cooler with ice and water, cases of Crest toothpaste, Dove soap, Degree deodorant, Playdough, candy, and school supplies like glue, glue sticks, pencils, markers, paper and notebooks. Plus a big box of Walmart schwag, like water bottles, reusable grocery bags, and squeeze balls.

We got all this stuff from her store for her and a co-worker to hand out. The XL was LOADED almost to the roof all the way to the front seatbacks.

That air pump for the suspension ran for like 30-45 seconds when first started instead of the usual 5-10 second test to level out the rear
