2007 Expedition Rear Air Suspension Issue

[Jttama]

I noticed that my compressor was coming on more often and seemed to be louder then usual. All of a sudden one day the rear of my truck was very low. It seems that the compressor went bad. My issue though is weather or not the air springs have leaks or not. How do I find out. Also, friends are recommending to me to install a Strutmasters Conversion Kit. Any thoughts?

could be a simple compressor swap...could be more...mine did the same thing and i was trying to hold off so i could do the coil swap...i had bad o-rings and something else and it was going to cost $1700 to fix...for $400 i had coil swap in hand...i advise doing the swap cuz this will happen again...every 7-10 years and there are just too many components to figure out what is wrong with it...

Thanks. Just ordered the Strutmasters set of four. I'll let you know hoe it turns out.
