Adkins used a couple of angle finders and a square to position the inner C on the axletube. This step is very important; not only must it be square on the tube, its angle, must match the driver side exactly. If it doesn’t, then caster won’t match side to side and the Jeep won’t drive properly. This is definitely a time to measure twice. Adkins made a couple of tack welds, followed by several more strategic tacks to draw the C into the proper position.
