Came pretty fast too. Just played with it for about 20 mins or so. Everything works fine. Gotta get a cheap laptop now

Clone
you can't "alter" anything with it but you can add modules/re-program/calibrate/re-calibrate and test functionality of most things.

I'll be bugging you soon with tons of questions sensei ..
Update:
Got the Yukon up on jack stands and couldn’t sense any extra play in the wheel bearing when grabbing the wheel at 12 & 6. With it being all wheel drive I couldn’t get it to spin very well. Went ahead and took the bearing off and when I spun it while holding it in my hand it sounded like a roulette wheel. Put the new one on and all is well now.
Awesome news. You might consider doing the other side since it’s probably not far behind.
That is the plan. This got me out of critical condition. Next will be replacing the other side as well as pads and rotors. I noticed some odd wear pattern on the inside of the rotor I took off. Looks like someone replaced the pads without turning/replacing the rotor so now the pads, which looks almost new, based on thickness, has a strange wear pattern. The outer 1/4”-3/8” on both the OD and ID edges of the inside pad is worn down more than the center field of the pad. I’ve seen them wear more on the outer edge than the inner edge due to bad wheel bearing, but nothing like this. Note, the radial marks are from pulling the caliper off and the thicker center portion of the pad scrapped along the outer ridge of the rotor.
looks like a little bit of rotor warp, rub your finger across it if it's not smooth then yep
I would definitely replace the rotate along with the pads. Rotors are so inexpensive nowadays it makes sense to do that. Of course those can probably be turned since they’re not drilled and don’t look like they’ve already had that done.
mostly caused by driving in standing water when they are hot

Noticed a popping noise when i make a left turn. CV axels possibly shot?

Hell a bad wheel bearing can pop when making a turn... Best to jack it up and pull the wheels...

I checked at a few local auto parts stores to get my stock rotors turned and they all had quit doing it. Two of the stores told me that they're making the rotors a hair thinner and cheaper now so they're not thick enough to be resurfaced. They are now "one-time-use/disposable". My OEM ones were plenty thick so I had a mechanic shop turn them. Had all four done. So far, they're still smooth as can be.
probably not unless it's consistent all the time, if you don't see a busted boot and grease all over then the cv is probably fine, swaybar bushings or end links would be more likely. these gm cv axles hold up pretty good unless the grease gets out.
