I was putting my yj up on a lift to install a body lift and i noticed one of the lines running along side my frame was broken, I'm not really sure what the line does. I know it is not a fuel line or a break line and i think it has something to do with drawing a vacum for my four wheel drive. However, everything works i can shift in and out of 4x4 and my engine doesn't sound funny so i have no idea what this line is for. Oh and i did finish the 2inch body lift however when i put the drive column back in apparently i put it in completely upside down and i really didn't feel like taking it back out again so i just pulled the steering wheel off and drilled a new hole on the opposite side of it for the horne...i hope that dosent affect anything. Oh and by the way my name is Denton Sweat and i work in the auto hobby shop on base.
