Not that it is a big deal but I thought it was kind of a neat mod and it only cost $15. Anyway it got me wondering how GM and Ram hubs work .... I think GM hubs are engaged 100% of the time? Does Ram have auto hubs?
Both Ram and GM use a electric motor to slide a coupler with splines that connect the axles internally in the axles tubes. When in 2 wheel drive these systems front u joints (ram) or CV joints (GM) will always turn.
Thanks ... I knew GM was different from Ford but didn't know how and didn't know how Ram worked at all.
