Service bulletin 68056356A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Axle Assembly, Axle Carrier, Axle Ring and Pinion Engineering is currently investigating concerns with pinion seals on the 2014-15 MY Ram 1500 Pick-up with a rear axle manufactured within the October to November 2014 calendar year. Please contact Ridhan Riyal at cell (810) 513-3832 for further instruction. If he cannot be reached with 15 minutes proceed with your repair.~ The DS Limited Slip Differential operates as a torque sensing device because when torque is applied to the differential gear set the reaction forces of the bevel gears apply an axial force into the clutch system providing the torque bias. When the input torque is very low the reaction forces will decrease allowing the differential to ACT SIMILIAR TO A OPEN DIFFERENTIAL (zero preload). Please do not confuse this with prior model year Limited Slip Differentials. See the service manual for complete details.
