Well, the other day, leaving work, reversing out of my parking spot with my wheel nearly at full lock, I got that soft clunk noise from the rear again. At this point, my opinion is that it has something to do with my bowed (Rough Country...didn't buy them myself) springs, possibly a bad bushing, or the orientation of my swaybar/end links. I already have Metalcloak's spring correction/retainer kit coming and I already have a replacement bushing for the rear track bar on hand. Beyond any of these possibilities, I'm at a loss and might just have to accept that it's there.
