Suspension compressor

[btbold]

I'm getting a "Service Suspension" alert on the dash of my 2007 Tahoe. Had it checked out and was told that the suspension compressor needed to be replaced. Can anyone tell me where the compressor is located, how to replace it and is it an easy fix

Rear Driver's side framerail. Fairly easy to do. Hardest part is dealing with rusted screws/bolts. You can get one from Arnott Industries or here: http://www.amazon.com/dp/B00A23V5EU/ref=dra_a_cs_ss_hn_it_P1400_1000?tag=dradisplay-20
