Here is a step notch install done by my 2 brothers and myself. luke tore it apart, adam did all the welding, and i played boss.
Adam's welding skills are amazing. he can run a perfect bead vertical, horizontal, overhead, and anyway you can imagine. i was going to do the install myself but he insisted on doing most of the work, so i didnt argue.
wanted to get my truck down quickly and cheaply. Also, with the 94 SS springs, the ride was quite harsh, and I wanted a way to soften it up a bit. So I decided to pull a leaf out of the pack for the time being. I looked around and couldn't find any real desciption on how to do it, so I wrote my own. Here we go:
The picture below is what you should do first. You will need to take off the disk and you will see the dust shield. When you use lowering springs it moves the knuckle up so it hits the shield and makes a terrible squeaking noise and makes a mark in the dustshield like this pic shows.
1)Loosen lug nuts
2)Jack truck up and put on jackstands
4)Remove brake caliper by removing two pin bolts from backside of caliper, use a 3/8" allen wrench. Secure caliper by string or wire, or set on a piece of wood, do not let caliper hang by the brakeline.
This HowTo will basically cover the install of a Barnyard Customs upper control arm for an s10. However many of the practices are the same with other control arms from other manufactures so it may be a good reference for you.
