I have a 2015 JKU Rubicon and just recently had my 4:88 gears installed. Everything seems to be fine until I went to engage the rear locker. 2WD, 4H, and 4L all work fine but when I go to lock the rear axil things seem to not work as smoothly. When I put the jeep in 4L and push the locker switch once and start to move forward the rear locker light keep flashing. I push the locker switch again and the front locker engages and the front locker light becomes solid (rear locker still flashing). I drive around the parking lot to see if I can get the rear to lock and nothing happens. Without any luck with the rear locking I come to a stop, turn off the lockers and put it in 2WD. Once in 2WD and start to drive off I hear a loud pop noise from the rear of the jeep and the body of the jeep shifts noticeably. I also hear a whine noise for about 100 to 200 yards right after but then goes away and everything goes back to normal. What do you guys think this may be?? Is the rear locker trying to lock but can't for some reason? When they did the install they accidentally broke a sensor in the front and had to order a new one. If the rear sensor was damnaged too is this what one would expect to happen?
