On Dec. 23, 2016, Service Bulletin No. 03-008-16 was issued. It addresses axle groan/moan/rubbing/shudder noise coming from limited slip differentials during tight parking situations for 2015-2017 Challengers. The new LSD axle oi/lubricant is Part No. 68083381AA.
i just got a recall letter on mine (2009 Challenger) and it was something about a KID fire extinguisher. never heard of that, wonder where it is located? they said only some of these have it , not sure if mine does, but going to the dealer today to find out.
