Step four: Grease the cup and install the bearings

Apply a light coating of grease to the driveside hub shell. Carefully place the bearings into the cup, using a pick if necessary to guide them into place. Reinsert the axle into the hub from the driveside, pressing the cone against the bearings.

Holding the cone against the driveside bearings with one hand, turn the wheel over, apply a light coating of grease to the non-driveside hubshell, and replace the bearings. Carefully place the bearings into the cup, using a pick if necessary to guide them into place. Screw the cone, spacer, and lock ring back onto the non-driveside of the axle.
