Quick question: air suspension

[sroth004]

I have not been active of late, hope you are all doing well. ‘05 4.8is, about 90k miles, all four air bags were replaced with Arnott’s (bags only, not the entire unit), the fronts 6-7 years ago, rears 2ish (I have the details, just not nearby), the X takes the Winter off here in PA and has been in storage since mid December.

Went to the storage garage yesterday to check on the cars and the front end was down a couple of inches, rear end looked ok. The system raised the front with no delay when I unlocked the car, as it should. Recognizing it should be a sealed system with no leaks, what are your results in terms of actual performance? Is a couple of inches drop over a couple of months of sitting typical or does it suggest investigation? I know the bags are linked so one weak bag would drop the entire front (or rear). If investigation suggested, given the age of the bags are they or another item the likely culprit?

I’m sure this is answered elsewhere but wanted to say hello to the group anyway.

Thanks

Steve
