In this video I disassemble Mercedes G (W463) transfer case to investigate how things work inside
W460 and W461 have no differential mechanism inside
High gear ratio: 1.00
Low gear ratio: 2.16
W463 got transfer cases with 3rd differential and locking mechanism
Early W463 (with engines like OM603) have manual high/low gear selection
High gear ratio: 1.05
Low gear ratio: 2.16
Later W463 (with engines like OM603/OM606) have manual high/low gear selection
High gear ratio: 0.87
Low gear ratio: 2.16
And more later W463 got this electric motor for high/low gear selection
High gear ratio: 0.87
Low gear ratio: 2.16
