Remove the nut, remove the bolts and remove a support hub (Fig. 3.81). Peel back seamed collar nut and remove the nut on the rear wheel hub. By supporting the outer ring of the bearing, press out the plug of the rear axle. Special tools (09455- 21000), remove the inner ring of the bearing from the hub. Special tools (09453- 33000B, 09545-21100) Extract the two sleeves from the support hub.
Check Check rear wheel bearing for wear and damage. Check the rotor speed sensor rear hub to the absence of broken teeth. Check the inner surface of the hub for scoring. Check the support hub for cracks.
Setting Special tools (09453- 3300B, 09545-21100) press in the two sleeves in support of a nave. Apply a thin layer of grease on the multi-function mating surface of the hub and bearing. Special tools (09221- 21000) press-fit the bearing into the hub.
