The time has finally come to step up to the next level in suspensions. I have decided to create a new tube chassis Baja with airbags and A-Arm front suspension. I will be using a Ford Mustang power rack and pinion steering, custom spindles and arms with full hiem joint adjustment. -MJ
Now the real work begins. The plan is to have a center frame section of 20" to accommodate the Ford rack, and have 18" long arms for what should be 20" of front travel.
A simple jig was made to hold the tube adapters in place. 1.25 diameter tubing was then cut to length and notched to merge into the rod end holders. A triangle of 11ga was added to the end joint for rigidity and my amazing but useless sheet metal dimpler was used to make a fancy hole.
The spindle was made of heavy wall square tubing with a section of the side cut out on either end. Flat bar was then used to fill in the gaps and frame the opening for added strength and to maintain the rigidity of the spindle. One thing to keep in mind is whether or not someone put flammable garbage into your makeshift welding stand. You will find out right away as soon as the flames are big enough to flicker around the sheet metal on top of the barrel. Oh what fun!
Holes were drilled in the tubing for mounting the rod ends with misalignment spacers. 3/8" flat bar was then drilled and shaped to mount the spindle to. I found that a '75 or later super beetle spindle has a bolt on flange on the end of it with the right angle. I opted for that instead of a full custom for ease of replacement. Time will tell on how strong they are.
