So, my mechanic replaced the right front air strut today and after installing it he found that it was still a little lower on the right side. He has a smoke tool to find leaks in air tight systems. It turned out that there was a small leak close to the compressor on the hose delivering air to that right front strut. Now the entire system is air tight and functioning as it should!!!

I still think it was worthwhile to replace the air strut because the front left had recently failed. I am sure this one was close behind. And it was sagging more than an inch over night sometimes.

I share this because his smoke tool made checking the system much easier. This would be a good tool to have to check the system. It feels great to know the entire front end is new on the X and should be good to go!!
