Boxing Lower Control Arms 0001 The first step is to locate the holes for sway bars.I took a set of rear lower control arms that were to pitted for resale. I cut the sides out and now use then for a jig to locate the sway bar holes.If you look closely or click the picture to enlarge it you will see that a drill is being used to locate the jig in the correct location to mark the sway bar bolt holes
 Boxing Lower Control Arms 0002  This is just another view of the “jig” clamped in place with the drill locating the “jig” on the lower control arm to be drilled for sway bar bolt holes.A stepped drill bit is used for a nice clean holes.Both sides of the holes are ground so there are no burrs. 
Boxing Lower Control Arms 0003 Many clamps are used to hold the insert in the correct location.Bolts are inserted through the sway bar bolt holes.Clamps are placed on the sides to hold the arm tight to the insert.

Boxing Lower Control Arms 0007 Additional “stitch” welds are made, once the clamps have been removed to provide room to make those welds.
 Boxing Lower Control Arms 0008 The “Stitch” welds are then all tied together into one bead with additional “stitch” welds. All these small welds are done to avoid any warping of the arm. Temperatures are kept as low as possible and still get good penetration on the welds.
