- Loosen and remove the end fitting by inserting a 5mm hex key in each side of the hub. Turning the hex wrenches opposite of each other (standard right-hand threads) one of the end caps will loosen. There is no way to control which end cap will loosen first. If the drive the drive side end cap loosens and is removed first the freehub body may removed as well.
- In some cases the non-drive end cap will loosen before the drive side end cap. If this occurs, completely remove the non-drive side end cap. The axle is broached to accept an 8mm hex key. Insert the 8mm hex key from the non-drive side and holding it firmly use a 5mm hex key inserted in the drive side to loosen and remove the remaining end cap.

- If also changing the cassette body bearings proceed by inserting a flat-faced punch though the cassette body ratchet pawl holder and use the tip to push to one side the spacer separating the two cassette body bearings.
- Remove the outer bearing from the cassette body by using the punch and small hammer to tap against the back of the outer bearing ID ring on alternating sides until the bearing is worked out of the cassette body.
- With a pair a snap ring pliers, remove the bearing retaining ring from the interior of the cassette body.
- Using the hammer and punch, gently tap the inner bearing from the cassette body as in #7.
- Replace all bearings in reverse order by pressing on the bearings' outer diameters using the appropriate sized bearing press tool.
