Astro Van steering knuckle mods. Making another jig fixture.
Most of the "tools" and fixtures I design and build are because of this Astro Van I am building. It is a Pro Touring style build with a radically dropped and big tired van as the end product. Nothing for this build is "off the shelf". It is NOT a '69 Camaro... :) So everything I do is one off, just like these front steering knuckles. I had to reconfigure the steering arm to work with a Corvette Steering rack that was used as the basis for the front suspension design.
Here is how I built the fixture to modify both front knuckles.
I bolted two plates together, through the lower ball stud hole.With those in place I welded a short piece of plate, vertically, to those plates. The 1/2" rod extends out to the tierod area that will get modified.

This is the "working" end of the jig. It is dual purpose so this one jig will work to modify both knuckles. The plate is bent down 15 degrees on both sides. That is the new angle the tierod end will be moved to.

Here you see the "new" position for the tierod end. The bottom of the aluminum spacer, with the bolt and nut on it. The tierod will get cut off and flipped over 180 degrees and rewelded to the knuckle. :)
