Hello, I have a 2006 Dodge Magnum Srt8 with about 118,000 miles on it. Heard a grinding noise/hum towards the rear, so I took it to the dealership. Sure enough they found metal pieces in the differential fluid. They mentioned that I should look in to a rebuild kit. Any ideas, where to get one? And what should I be looking for? Also is there any TSB'S related to this issue, as even the dealer said this is abnormal. Thanks in advance!
