Replacing front Air Springs

My 2011 Overland is nearing on 100k miles and starting to show signs of worn front struts. I get a loud knocking sound going over small bumps and larger bumps on the highway seem to make the front end shudder a little bit. Have checked out the front suspension and everything looks tight, including the sway bar end links. Signs are pointing to the struts being worn out, so I've been looking at replacement options. Seems there are a few aftermarket companies offering these now - has anyone tried the Suncore units? Price is pretty attractive at $500 for the front pair. Also, is it possible to just buy a tank of the nitrogen and fittings to refill or are there special tools needed to refill the system?

If the dealer does it he uses his scan tool air suspension control module routines to fill the spring from the reservoir, run the air mass calculation, add nitrogen or deflate, enable the air suspension.

Memory is fading but there was a thread awhile ago covering how to do some/all of this with a modified scangage I think. You just need some fittings and a tank to fill/top off I think, but there was quite a bit of discussion awhile ago. If one of those guys don't jump in here soon, you should be able to find the threads.

Thanks, I was able to find a few threads on the subject. I didn't really find any examples of someone getting this done without the dealer though.
