Air suspension question
Hello all. I just picked up a 2000 Eddie Bauer 4wd with the air suspension. I have done the search thing and have been reading alot about it. I have a couple questions. Is the compressor suppose to run like all the time? Mine seems to run for 5 minutes then shut off for 5-10 minutes then run again. Also it is pretty loud. With the radio turned up you can still hear the compressor running. Thanks.

Yeah, the compressor having to come on allot means you have a leak in the air springs. Do this easy test: Get inside, turn the ignition on and let it pump up. Then turn the suspension switch off. Then DRIVE(not just let it sit) the vehicle for "up to" a few days. If the rear goes down....you have a leak.
Your first goal is to repair the leak(s), then keep an eye on it to see if the compressor has any life left in it, by how long it takes to pump up. With just you in the vehicle, it should take less than 30 seconds to pump up to normal ride height. If it takes any longer than that, or if the compressor is really loud, you may want to plan on getting a compressor/dryer soon.
While i'll bet your mounting insulators are gone, I would bet 95% of your noise is coming from inside the compressor.

Thanks for the reply's im going outside to see how long it takes to pump up and check the compressor mounts.
Ok, well first I turned on the switch and started the SUV, the compressor cycled on and off for 10 seconds for about 5 times, then the last time ran for 30 seconds and stopped. I crawled under the back of the truck and noticed the air bags full. I should have looked at them before starting.
The frame is about 1 inch off of the rubber stops on both sides. I turned off the switch and will check the SUV in the morning to see if it went down. As for the noise it seems it is the compressor. If I grab it and push on it, then it quiets down a bit. The mounts seem pretty good. Maybe the compressor was replaced in the past. Who knows. I will check back again tomorrow.

On these systems, theres a solenoid on each air spring that keeps the air in. In other words, if the air spring wasn't leaking, there would be no reason for the compressor to come on....other than right after startup.
