Hello everyone, just wanted to introduce myself. I have a 99 with the 4.0. As a kid I used to go out wheeling with a family, it was always a lot of fun. I finally got back into it when I got this truck. It has been so much fun. I have taken it to Telluride, Moab, and many trails around Arizona. Of course I try to do most of the maintenance myself, but I recently goofed something up. I mixed up the OEM bolts to the upper control arms and I'm having trouble placing them back in the correct order. They have a two letter code on the loose plate side. Does anyone know the location of each piece or point me in the right direction?
