I did the EXACT same thing :icon_mad:. Got an alert light on the dash when i started it... Corrected the install. Tube was smashed but intact. light on dash hasn't returned :smile2:.I put in the 7271 Hellwig bar yesterday. I have not driven it yet because when installing I pinched a tube in the U-bolt. I removed the U-bolt and fixed it but I don't want to run the truck until I figure out what I pinched. I have an arrow pointing at it in this picture. Anyone have an idea what it is and if I am ok to use? It is on the back side of the axle.
