I have a '96 that has possible leaky front air springs. The funny thing is that they don't always leak down. And sometimes it seems to depend upon the weather. If it's a cool, humid night, the front end will be on the ground the next morning. But if it's a warm, dry night, it can sit all night and not drop an inch. And it sometimes drops a couple of inches while I'm at work, and sometimes it doesn't drop at all. I'm beginning to think the suspension has a mind of its own. I'm hoping that it's the solonoid seals or a leak in the line. I just don't want to have to replace my air spring/shocks again any time soon. It's not that it's hard to do,(I can change both air spring/shocks in less than an hour in my bacvk yard!) I just can't afford to buy another set right now. But it is frustrating as hell, and it's really taxing the compressor.
