Not warped, but not trued & turned correctly. Cleanliness is usually the culprit, metal shavings are a byproduct of drum turning and often times someone in a hurry will get a shaving accidently sandwiched between an alining surface of the lathe & drum with a not so good outcome such as you discribe. If this did happen I would insist on new drums. When they re-turn your drums to put them back to true they remove even more metal drastically shortening the drums life and heat dissipation ability. Another item to address is did a shaving get in between the hub and drum surfaces when they were swaged back together forcing them to run out of true? -------Original Message------- From: bluesport62 Date: 7/20/2011 6:46:08 AM To: Chrysler300@xxxxxxxxxxxxxxx Subject: [Chrysler300] drumbs hi gang. is it possible that even afteR cuting drumbs they still can be warpted. this is in relation with my last post about RUMBLE STRIPS.VIBRATION IN STEARING WHEEL WHEN STEPING ON BRAKES.
