Ok just replaced my air ride rear shocks with rebuilt Arnot. Not to bad but the darn top bolt on the passenger side was hard to get the socket on. In the event of trying to get the socket in to hold the bolt among the lines that run through there, I must have unplugged a wire that has the female end attached to the top of the frame rail. I didn't know this at first so when I started it up the ABS and traction control light came on. After reading this page went back in and found it hanging there and plugged it back in. No more service lights.
