When the wheels are freewheeling, with the locks disconnected, all the internal components of the front axle don't move and that will save a little bit of fuel.L60Boerne wrote: ↑Thu Oct 16, 2025 12:51 pm Greetings, I solved my own questions. My experience indicated that the hubs do not tottally lock the front axle because Patrol's have open or limited slip differentials. Still one must ask what do they hubs really do if they don't lock the front axles? I guess it is just a more positive connection.

Japanese 4x4s didn't come with locking hubs at the beginning. They were fitted first here in the USA. And the reason is simple enough. The Patrol and Toyotas have "constant velocity" joints instead of universal joints in the front wheels. The use of locking hubs is noticeable and more beneficial in the second case (universal joints)
