Ok, so I'm rebuilding my old as a spare. The centering ball was a biatch to get out and I've made a couple of little indentations around the top of the centering ball retainer (the one on the t-case flange) Does this come into contact with anything or am I ok if I just grind any burrs off? Again it's not bad, just not perfect.

Thanks,
Jim

 

A photo or two would help.
