How-to replace front shock w/air suspension?

I've seen earlier posts for a DIY air spring change, a search should help (could have been on one of the other forums too). Not that difficult at all, just need to take care it is all out before letting air in. You should probably buy the WIS for your car from mbusa.

If you can find any articles on replacing air spring you might want to start a thread and see if anybody there can help.
Good luck on your project and keep us updated on your findings.
1. Raise front of vehicle, support with stands.
2.Remove wheel
3. Release hood and disconnect air line from top of air strut.
4. Remove 3 13mm nuts that hold strut to tower.
5. Remove mounting bolt from lower control arm(21mm I think)
6. Remove nut that attached upper control arm to spindle(16mm) and strike the spindle where the upper ball joint goes through with a large hammer. Could take a few whacks.. but don't miss(hint, keep the nut threaded on slightly so you don't damage the threads if you miss)
7. Remove strut.
Install in reverse order, start car and depress raise switch.. then wait for the strut to fill.
