Replacing Leaf Springs on a '95 jeep Wrangler

Actually you need two sets of jack stand to do it properly and safely and a floor jack or two. You want to raise font end and raise it enough that the front wheels are about 3 inches above the ground and place it on jack stand supporting the frame just aft of where the rear spring attachement is. Place jack stands under axle but not really supporting it at this time (maybe 1-2 inch clearance) and remove front wheels. Use a floor jack to adjust the height of the front axle if need be as you unbolt springs and remove them. When yo install the lifted one use the floor jack to suspend axle while you readjust jackstands supporting axle to get correct height to attach new springs. One word of caution, before you get to deep into this, make sure that you can remove the 4 bolts at ends of springs where they attach to frame support because they can rust and become stuck and make it a nasty job. If they are not "frozen" and you have some air tools, you can do the whole job in less than 2 hours from start to finish. With a extra set of hands I can do one in less than a hour if the end bolts are not frozen. Air tools help a LOT with this task.
