I will say that the Rubicon rear brakes fill up the 17 inch wheel. There is very little room for the wheel weights and they need to be in the correct location or they will get into the caliper.
Pads are not in correct contact with rotor's take it to the dealer and have them pull the rear wheels and check the pad position in the caliper's. Shiny bands on rotor is where the pad is contacting and the rust band is not contacting the pad. The pad cleans the surface rust off the rotor.
Somethings not talking to the other, I wouldn't think the cameras are different for the JL to the JT but they might be. Worst case call the service department and ask a service tech. They might have the answer, or at least point you in the right direction.
1800 sq ft and had to have 220 volt for air compressor with air fast pipe from Rapid Air and welder set up in a corner. Epoxy coated floor, shelving, room for tool boxes and work benches. Just a little messy....... Before and after. Only took 40 years to get it done
