AVM FREE WHEELING HUBS
AVM free wheeling hubs are a quality, tough and dependable replacement for factory fitted hubs. Used to connect or disconnect the front axle assembly on part-time 4WD models, they can also be fitted to early model 4WDs that have fixed hubs to stop unnecessary differential rotation and resulting wear.
The outer end of each front axle is a splined section over which the inner hub fits. Around the outside of this is an outer hub which is connected to the wheel. A clutch separates the two. This clutch can be engaged by oblique grooves cut inside the free wheeling hub control knob that is mounted on the outside.
