^ Remove the electrician's tape.
3. Install the outer rear wheel bearing.





4. Start the hub nut making sure that the tab aligns correctly in the keyway prior to thread engagement.





5. NOTE: The following hub nut tightening sequence will prevent side-to-side end play of the hub and brake disc assembly.

NOTE: Apply inward pressure to the socket to separate the ratcheting components of the hub nut.

To adjust the bearings, tighten the nut to 95 Nm (70 lb-ft).





6. Back off the nut 90 degrees.
7. Tighten the nut.
^ Tighten to 24 Nm (18 lb-ft).
^ To verify that there is no side-to-side end play, attach a magnetically mounted dial indicator to the spindle end and place the dial indicator tip on the outboard surface of the hub. Check for side-to-side end play.
^ Final bearing adjustment has zero end play. The maximum torque to rotate the hub is 2.3 Nm (20 lb-inch) when end play is zero.
