As some may recall, I live in a beach town and don't have a place that I can leave my car apart and immobile. Therefore, I can only do limited projects that can be started and finished in a day. My rear springs sag a lot. A previous owner put on air shocks, but they leak air, so sag out after a day or two. Also, the air lines terminate back at the diff, so it's a pain in the rear (heh heh) to air up. New springs are coming, but I think I always want air shocks so I can keep it from sagging when full and carrying stuff. I've got a new set and new air lines. My question: Can I realistically pull it apart and replace the shocks in a borrowed driveway in a reasonable day (5- 6 hours)? What about leaf springs? I've got to get in there to measure the eye diameter to order new springs. Any gotcha's when I do that? Advice?
