I have been trying to get the pinch bolt out of the near side supension on my all road. First I tryed the traditional methon of plus gas and a hammer which did not work . -I then started drilling which was taking forever -The the blow torch came out which has done no good at all. Control arms need replacing now, the heat also damaged the airline and blew a hole in it. Has anyone replaced and airline before, any tips would be much appreciated. -Any tricks getting the pinch bolts out as well would be much appreciated?
