so, he's saying the cam bolts are original and rusted/shot/never been moved.
The camber and castor are off on the passenger front wheel.
How would he adjust this if the bolts are seized up? Are you saying they are fixed measurments, set by the factory? or how are they adjusted?
thanks for the knowledge old master...

Ok, I figured he was trying to sell you the cam bolts just to jack up the bill, but if they're rusted, that's a different story. Here's a picture of the cam bolts:http://www.coolparts.com/thumbnail.p.../K8460_TOP.jpg

The upper control arm is shaped like the letter "V". The ball joint is mounted at the "point" and there is a cam bolt on each "leg". Each "leg" is sandwiched between two "ears" on the frame, and the cam bolts secure them in the proper place. Rotating the front cam in one direction adds camber and caster. Rotating it the opposite direction sutracts camber and caster. Rotating the rear cam in one direction adds camber and subrtacts caster. The other direction subtracts camber and adds caster. When camber and caster are adjusted, the cam bolts are tightened to lock them in position. Moving the cams to the proper position can be tricky during the alignment, especially when replacing the cam bolts because you're starting from "scratch".

GM T series, (4WD) come from the factory with all four cams installed and they are fully adjustable without buying any additional parts if camber and/or caster need adjustment. The GM full size do not come with the cams. If they need camber and/or caster adjusted, the cam bolt kit is necessary.

thanks great write up too!

So, while the sun was out today, I started messing with the rust at the bottom of the third door. Bad idea. Once it started flaking, a hole opened up as I suspected. However the 2 inch pile of crud left on the ground was a surprise. Now the whole bottom of the third door is shot, which sucks because the rest of the truck, panel wise, is clean. It almost looks like something is collecting inside the door itself. Once a hole opened, I kept tapping the door and debris kept falling out. I'm wondering if the whole door has to be replaced, or if they make a lower skirt that would weld up/seam under the molding.
So in doing this, I pissed her off and she decided to throw the 'service engine soon' light again.....
figures since I just posted a couple days ago how good she's been to me...

why did I mess with the rust on that door?
