[HO455]

I got up on the alignment rack again today. The first photo is from Friday of the starting point. I certainly got lots of caster! More than I wanted. I started with the existing shim packs with one exception. Instead of a 3/4" or more stack of shims I made some 3/8" and 5/16" spacers to reduce the number of shims. After much back and forth I got things pretty close to the specifications provided by BMERDOC in his alignment thread. (Photo2)

I came to the realization that the air bags really affect your camber settings. I picked a ride height but I may go with a higher one as I think I have right camber but i am out of room on the bolts. By going with a higher ride height that should allow me to reduce the number of shims instead of having to install longer bolts to hold the control arms on. Photos 3 & 4 show the shims and bolts. The last photo is the rear axle readings which show my need for an adjustable panhard bar. With the lowered rear suspension it is pushing the rear end to the passenger side and as a result it no longer perfectly in alignment with the frame but it is -.10 degrees off of center line. It actually is better than I expected it to be. I bet if I were to replace the bushings it would get worse. Sometimes old and worn out is your friend.
