10 Spline Free Wheeling Hubs
Suitable for use on all series front axles fitted with 10 spline half shafts.
Complete kit comes with gaskets and seals.
The idea of a free wheeling hub is to reduce drag and wear on the front axle drive train components, because your road wheels turn the whole axle,diff,prop shaft etc, even though your in two wheel drive on the gear box.
Free wheeling hub allows you to disconnect your front wheels from the half shafts, so you no longer turn the front transmission over hence the reduction in drag and hopefully slightly better fuel economy.
The one down side you have to remember to put them in the lock position before you engage four wheel drive otherwise the front wheels will receive no power from the transmission.
