Fabricated A-Body spindle ideas and discussion

About losing preload on the rear, the cv stub is working against traction. Also, the caged plates /prevailing torque nuts are one time use and the hub to spline engagement is supposed to be a wedge fit. Any rotation between the hub and the cv stub on the splines from braking or traction will loosen the clamp load (all right hand thread. Spring-like axle shafts such as 300M that absorb torque peaks help too). Not a problem for the front. Spindle type mounting is better than a bolt/cv stub since the weight of the rotating assembly is reduced.

I once bought cobra axles from Factory Five to use with a miata 8.8 (I had the mazda hubs broached) but then realized why the half shafts were so cheap (about 25 years ago). They were sourced from China and the splines could be rocked on the hub. I sold them to another builder (full disclosure to the buyer). I don't know if he used them or not. I had Moser make custom length shafts so I could use oem cv joints.

I have granada spindles on my '67 mustang with a UCA lowered an inch like the GT350. When deciding on a name, I'm guessing cortex never heard of a cotex. Lovely product though.

I need to retire so I have time to work on all this (rough) stuff, but then I wouldn't need to drive anywhere. Too many irons....
