For RAM, there's a center axle disconnect, but that's it. It's an electric solenoid that engages the passenger side half shaft (vs. the older vacuum design). No hub disconnect that I know of, but there are after market manual hub kits and center axle disconnect disablers out there as well.

Coming up the mountains here in Ca last night. Snowing and slippery. Put truck in 4x4 light came in saying engaged. Driving very slowly and almost slid off road with two kids and wife in car. Then noticed that there was no front traction happening. Locked hubs manually and all was ok. I think this is a serious problem. If in auto and dash confirms 4x4 engaged then it should be. I am just very lucky to not have seriously hurt my family or someone else. Is this a recall on Fords part I truly think they need to be held accountable if so. Thanks in advance for any info.

been through this issue a few times with my 7.3 trucks. every time it was the hub seals leaking. it would leak the vacuum down and the hubs would not engage. the telltale on the 7.3 is if the defrosters come on when you put it 4wd. (drops the vacuum for the climate controls.) don't know what will happen if the seals go bad with the 6.7 vacuum system.
