I ended up doing the same as charliebren and replaced the whole strut assembly with a unit from Arnot Air Suspension. Everything worked great after that. Since then I was T-Boned at an intersection, rolled, and spun around. Needless to say, I don't drive the same Navi now. I went with a 2008 which puts me on a different forum.

I just wanted to say everyone here has been great. This is the best place for online help I have ever experienced. I haven't had any problems with my 08 Navi yet but when I do I will be back to FTE for help. Talk to you guys then. Thanks for everything!
