no they arent, I have worked at chrysler dealerships for the past 10 years, they take them off all the time. How do you think they get in there and fix window motors, wiring, etc.? Just buy a whole new door already painted with glass and everything already in it and install in on the jeep? What if you latch breaks? I guess you are fuked cause you cant get the door open to get it off and install an entire whole new door. If you cant get them off then take it to a repair shop so they can do it for you in about 15 seconds.
