Mopar Performance P3690715 Shaft Diameter

Well, I thought Iā€™d buck the normal trend around here by providing a conclusion to the original issue posed!
Checked the shaft on v blocks - was straight.
Determined that bind witness marks were fairly uniformly distributed around the shaft.
Cleaned up lower shaft on lathe by turning it down .009ā€ - lower shaft is now .440ā€
Shaft now looks good & turns perfectly - no bind!
