The air suspension compressor on my 2008 Cadillac Escalade was making a very loud sound when it ran it it seemed to run more often for a lot longer than it used to. I suspected an a leak from the piston in the compressor. In this video I go step by step on how to replace the air compressor with an aftermarket Dorman 949-001 Suspension Air Compressor to replace GM Part #20930288. I got this for $160 from Amazon as a full plug and play replacement.
This should be the same for a Tahoe Yukon Suburban Avalanche from 2007-2014.
This is for the Cadillac ESV, EXT, GMC Yukon XL, etc.

This should be similar for all cars, but the Escalade shares a lot with a Tahoe, Suburban, Silverado, Denali, and several other GM vehicles.

Tools required:
Needle Nose Pliers
13 MM Deep Socket with 6 inch Extension
Screwdriver or Trim Pry Tool
Large Zip Tie
Rust Penetrating Spray (optional)
