    • Remove the freehub body

      • Be careful not to lose any of the pawls or the pawl springs

    • Remove the freehub shim

      • This is a thin washer. Be careful as sometimes this can stick to the inside of the freehub body or the bearing spacer

    • Remove the bearing spacer

    • At this point the hub is most of the way apart, you can service bearings, replace worn parts or just clean things up

    • Now lets put the hub back together

    • Start by lightly greasing and setting the bearing spacer onto the driveside hub bearing

    • Next, slide the freehub spacer onto the axle.

      • Install the spacer so the flat side is against the bearing and the tapered side is facing out from the hub

      • Note: This spacer is not used with the XX1 compatible XD driver

    • Install the freehub body into the axle

    • Slide the freehub shim onto the axle after the freehub body

    • You should now have the axle, freehub spacer (not used with the XD driver), freehub body and freehub shim installed on the axle.

    • Slide the axle assembly into the freehub spacer and hub shell

    • Turn the freehub body counter-clockwise to compress the pawls into the ratchet ring in the hub shell

    • For information on lube and service for the freehub body please see our freehub service instructions

    • flip the hub over and install the non-drive endcap

      • Remember, this endcap uses a reverse thread so turn it counter-clockwise to tighten

    • Turn the endcap by hand to adjust bearing preload until the hub no longer has bearing play

      • Cone wrenches can be used, but are rarely needed

    • Tighten the non-drive endcap using a 3mm hex wrench to 3nm

    • Put one drop of freehub oil on the rubber dust seal and install the freehub dust seal lockring
