You're welcome Ya, the Armada is a great vehicle over all.hey thanks for the great reply.
A big relief that it's probably an issue with that particular car. Sounds like I should continue the hunt and keep test driving them.
Most obvious is if the rear end is sagging. The springs are intentionally soft, relying on the air shocks to keep the ride level. The Armada will usually sag under it's own weight on those soft springs if the air system isn't working. You can confirm also by piling on extra weight with either a teenager and his buddies, car dealer sales staff, a trailer, etc. The compressor should kick on in about 30 seconds or so to level out from the extra weight. The compressor is located underneath, behind the drivers side wheel well. You can hear it when it turns on.Is there an easy way to find out if the air compressor went out?
As far as I know, there is no significant difference in the 2011 from the other similar production years 09-12... maybe changes to some tech upgrades i.e. sound, navigation? Hopefully someone else will chime in here....I been doing some reading on them and seen on Car Complaints the 2011 is rated higher then most others between 2009-2012 anyone have a 2011 and can give me more input?
