Front Shock Blow Out

Front Shock Blow Out
Well, it happened, I went out to the car and it looked very low in the front so I unlocked the car, which must have activated the air suspension and I heard a loud hissing in the right front wheelwell. The car did not rise up so I'm sure the right front shock is leaking big time. I started the car and backed it up and the "vehicle too low " came on. I looked long for the thread where Brutal outlined the steps to replace one of these and got tired looking. Does anyone know where this is? Many thanks in advance.
I ordered two new shocks from Arnott, I'll just replace them both, assuming that if one is gone, the other can't be far behind.

I was just thinking about the symptoms and realized that although only the right side was hissing as it dropped, both fronts went down together. This must mean that either the fronts are on a common air supply or the other front went bad at exactly the same time (very unlikely). I hope that since there is only one height sensor for both fronts, they share an air line. I still plan to replace both shocks but I started worrying about my diagnosis.

Furthermore, after I completed the repair, the suspension system was apparently locked in "jacking" mode and refused to raise the left shock at all until I drove the car for about a mile. I did not understand this at first, so my troubleshooting included checking the compressor and air supply - when I loosened the line to the right front shock, there was obvious high-pressure air in that line while the left front was still completely empty. In addition, I saw that the air lines to the front shocks are independent lines that run from the control manifold in the trunk and up through the left front fender well.

All I know I learned from glancing at the thread above! Maybe I am incorrect.

Oldmots,
If 1 front shock collapses the system will lower the other front shock to keep the front end level, left to right. It does this by checking the level every 30 mins or so, I think.
The actual job of replacing a shock is not so bad. I did it in a non hurried 3 hours. The second took me 1 1/2 hours.

Each air spring has a pressure retaining valve whose purpose is to retain 3 bar (43.5 psi) within the air spring at all times. That protects the air spring membrane by preventing it from creasing. Therefore if you have one bad spring the other one shouldn't fully deflate.
It has a similar feature for vehicle hoists.
