Working on putting a new front susp. and steering in a 34 Ford. Today a friend was talking about a death-wobble situation and something he said made me go back and check caster on each side. I have about 1.5 degrees differing caster side-to-side. See pics. I have no idea what the axle I have is other than it's a new axle, not Ford OEM. I know many will say that an original Ford axle is the best to use, and I'm sure they're correct. I just don't happen to have one and would like to use this one if possible, but certainly will replace it if I must. What is an acceptable amount of caster difference side-to-side? Thanks. P.S. Just in case anyone has a question, I'm using a precision ground V-block clamped to the new king pins and bushings, then a perpendicular ground steel bar to set the angle finder on. King pins fit spindles really nice with no slop. Also 33-34 split wishbone with adjustable perches etc...no twist forced onto the axle.
