Front Spindle Inner Wheel Bearing Problem
Not bad thoughts and having been a Ford parts guy for many years was actually my first thought. Unfortunately, not the problem in this case. I looked up my own parts and have also verified the number stamped into the race and roller. Timken bearings, so poor manufacturing is probably not the issue either. Parts spec out, including the seals. I even checked against my Ford 1960 - 1967 Quick Refernece manual and by application there just aren't any other options. Perplexing.
What I have found since I first posted this is that if the race is seated all the way down to the stop in the hub, the seal bottoms onto the spindle. If I leave about 1/4' gap between the stop and the bottom of the cup everything will line up perfectly. Problem with that appears obvious, and this is a race car so this is not the fix.
I do see some wear on the spindle where the inner bearing rides against the stop. I'm beginning to suspect that my spindles are dead but I don't have any dimensions to use to verify. Hard to believe though that more than 3/16" of material is gone from that surface. The kind of heat that would have given off would have turned the bumper blue!
I'm open to all possibilities, including wadded up old parts guys.
