Well for one thing, if it's centered your wheels won't rub if you run the BFG muds, and will only rub
slightly with the AT's, and if the bushings are good they won't squeak all the time.
Your theory of drive it till it drops is sound. Reminds me of another Colorado Hummer driver I know
I was wondering if anyone has replaced theirs lately and what kind did they put on? I can't seem to find the Energy Suspension ones Phil is talking about. It's like they discontinued them.
