What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I've got the AXN rear axle installed! (I think)

Currently the front and rear diffs have different ratios..
I haven't removed the front driveshaft yet (Anything else need to come out for it to clear?)
Will I be OK so long as I don't engage 4WD?

Planning to write a stock 3.42 tune in the morning and give it a test run..

AXN axle on the road!

First drive impression is.. Not noticing much improvement due to 3.08 to 3.42 change..
Off the line feels the same. Shifts sooner, but driving around doesn't feel more torquey.

Partly because I had 1-3 unlocked in the 3.08 tune, running stock 3.42 tune now.
Will drive it a good week or so before I tweak the 3.42 tune.

My passenger side mirror just stopped folding the other day.
Not looking forward to messing with it, but it shouldn't be bad if I do the glass removal method.

Is there a filter back here or do I just shop vac the grille slots on this rear AC intake out?

Looks like carpet padding behind there.

I always thought it was just carpet padding.
No cabin filter up front so why would there be one in the rear?

Changed the air filter, used some CRC MAF cleaner and pulled the airbox so I could clean it out with soap and water.

No filter. Yep just carpet padding.

The rear blower stays cleaner than the front one.
I think all the dust settles out by the time the air makes it to intake on the backside.
Also there is no fresh air intake for the rear.
