Looking at 08 Yukon 6.2 AWD need input

I'm not sure why people freak out over the rear air suspension. Mine were blown when I bought my Denali @118k miles. For about $590 and about an hour of my time I swapped out the two rear air shocks with reman Arnott's that come with the upgraded Goodyear rubber and a new air compressor. Has worked flawlessly ever since and seriously maybe the easiest work I've ever done on a vehicle. Was actually easier than changing the damn plugs and wires on this vehicle!

Long story short - don't be afraid of the rear air suspension, it's an easy fix and will only cost a ton if you take to a dealer. You can even buy two new shocks for like $450 total on Amazon but I wanted the upgraded rubber since that was a common failure point and I tie a 7000lb 25 foot Mastercraft boat ..

Is there a guide or write up on how to do this? I tried searching and couldn't find anything.

Good luck.

That's a great guide! I just used this video from Arnott that shows how to swap them. I can't remember if I found a guide for the air compressor, but it was super easy. I think three bolts and disconnect two air lines and the relief line running up by the fuel filler. Very very easy.
