I would add, when we make spindles, we are extremely careful to only have a 0.0005 clearance between the spindle and the bearing. If there is any more, the bearing will start to walk around on you...especially under hard driving.
I would strongly advise any of you who are using old spindles to check them throughly. By necessity, they are made of high quality steel which loves to corrode. ANY corrosion is cause to immediately reject the part.
We once took an original spindle off of a Cobra and sent it out for testing because the bearing surface was giving up. We noticed a slight rust spot on the surface and didn't give it much thought. By chance, the lab cut the spindle right through the rust spot to do the chemical anaylsis...
The rust spot was about 1/16 of an inch on the surface...and 1/4 of an inch across 1/8 of an inch deeper into the part!!! Any rust means give it the Navy float test.
