Ok I tried this afternoon to put my 2" leveling kit on my 06 Frontier XE. I followed the instructions and even printed out ones from PRG just to have better instructions. Anyway I got to the top control arm on the spindle and both instructions said to take the cotter pin and nut off and then to hit the spindle with a sledge to break it free so that you take all the tension off of the shock assembly. Well I tried that and it didnt work. I could not get the arm to break free so that you can get to the top of the coil and shock assembly. I took the assembly out and put the spacer on and of course I found out you cant get the bottom shock bolt back in since there is still tension on the lower A arm. I know that there are quite a few people who have done this already and I would like to know if there is a trick or special way to do it that I dont know? If anyone can help it would be awesome since I am really anxious to get it installed.
