My 04 100 series is sagging to one side in the rear. It's about a 1"- 2" sag. Before I have someone check it out I was wondering what it might be? It's got an ARB lift kit and ARB shocks / springs installed about 25K miles ago. Thanks!
The springs could be installed on the wrong sides, or you could have a weight imbalance. I suspect the first option, and it's only like a half hour to swap them to see.
