Air Spring Question

[jab23]

About to embark on replacing my air springs with the Arnott bags, but was curious of what other causes of deflation may be beyond bag leaks. The reason I ask is because they have deflated 3 times in the last year. Once after I change my summer/winter wheels over in the spring. It seemed related to jacking the car and I thought I maybe confused the system. It then happened two weeks ago after car sat for 5 days. Came out this morning and deflated again. I had jacked one side of the front up yesterday to clean the hub and mating surfaces (gets rid of clicking noise) so I'm just curious if jacking is causing it.

Is there a level sensor or something that the jacking may be effecting?

It's a 17 w/54k miles, so replacing bags is probably good preventative maintenance anyhow.

Could be a compressor leak

I think that you may have a leak somewhere, as these bags aren't a common failure point. I replaced my bags a few years ago, and that are still good to go now. Most common issue for these bags are dry rot and cracking due to age. The next time your under there, use soapy water in a spray bottle and soak every connection down, to see where the air is bleeding out.

Thanks you both. I'm going to replace the bags anyway as it's a cheap fix and piece of mind. I'll have to spray around the compressor connections etc. to see if the air is leaking from somewhere other than the bags.

I just though it odd that my deflations seemed to come after jacking the car up.
