2017+ Ram 1500's with the C235 Rear Axle require a different 75W-90 lube. The spec is Mopar MS-A0160. The Mopar 75W-90 product that meets this spec is not interchangeable with other 75W-90 gear lubes.
Is anyone aware of an aftermarket gear lube that meets this spec, or can advise on the reasons behind this new spec?
