Without or disconnected shocks, look to articulate the Jeep to measure your shock lengths. If you live near an industrial area, some have a ramp on the back of the building. Crawl up at an angle on the side of the ramp (driver's side is easier to see)(permission first is a good thing), once you lift a rear tire, park it. Measure the lengths you need eye to eye. Also look at the front setup as well.
Check your soft brake lines. You'll need longer soft lines for you to turn the caliper away from the frame. Next, look at your ds yokes to make sure they are not binding. Full flat droop is best to look at yoke clearance. But articulation is a good way of seeing the issue since you are already underneath it.
For the rear, I've noticed my shock's body is hitting the rear axle during cycling (basically at droop). My frame mounts are still good and haven't rusted enough to break off. MORE has a shock bracket that locates the top of the rear shock more forward.
You can measure at full droop in the garage by raising the frame high enough, supported by frame stands, and remove the rear tires, let the rear axle droop all the way. But articulation forces the opposite side of the axle to droop when it other side compresses.
