This is page RA-3 of a factory service manual section covering the REAR AXLE, uploaded as part of a Nissan Micra manual set. The left column details rear hub Installation: installing bearing outer races into the hub using special tool KV401021S0, placing the inside bearing and installing a new grease seal (seated 0-0.5 mm / 0-0.020 in below flush) with sealing lips coated in multi-purpose grease, and packing the hub cap with multi-purpose grease. The right column details Preload Adjustment for the rear wheel bearing: tighten the wheel bearing nut to 25-34 N·m (2.5-3.5 kg-m, 18-25 ft-lb), rotate the hub in both directions to seat the bearing, loosen the nut to zero preload (0 N·m, 0 axial end play), then retighten to 9-12 N·m (0.9-1.2 kg-m, 6.5-8.7 ft-lb), rotate the hub again, and tighten once more to 9-12 N·m. Illustrations (SRA326, SRA546, SRA913, SRA414, SRA415) show the tool setup, grease seal installation depth, grease points in the hub cap, and torque wrench use on the brake drum. A reader can learn the correct torque values, tool number, and step sequence for rear wheel bearing service.
