Q: How do you remove and install the rear wheel bearings on Nissan 240sx?A: To remove and install the rear wheel bearings on a 1982-89 Stanza or Stanza Wagon 2WD, first raise and support the vehicle safely, then remove the rear wheel and release the parking brake. Use a thin tool to work off the center hub cap, tapping gently with a soft hammer if needed. Pry off the cotter pin and take out the adjusting cap and wheel bearing lock nut, being careful not to damage the O-ring in the dust cap if equipped. Remove the rear drum along with the outer bearing, washer, inner bearing, and seal inside the drum, then extract the inner bearing and seal using a long brass drift pin. For installation, place the inner bearing and seal in the correct position within the brake drum and reinstall the drum on the vehicle, adjusting the rear wheel bearings afterward. If using a one-piece bearing, simply torque the wheel bearing lock nut. Install the outer bearing assembly, wheel bearing lock nut, adjusting cap, and a new cotter pin, then adjust the wheel bearings as necessary. Finally, install the center cap and wheel assembly, knocking out the wheel bearing races from the brake drum with a brass punch. For the 1990-92 Stanza, which uses a one-piece bearing hub assembly that requires no maintenance after installation, raise and support the vehicle, remove the rear wheel, and detach the brake caliper assembly without disconnecting the brake hose. Remove the wheel bearing locknut and bearing hub assembly, then reverse the procedure for installation, tightening the locknut to 137-188 ft. lbs. For the Stanza Wagon 4WD and 240SX, which also do not require maintenance after installation, raise and support the vehicle, remove the wheel bearing lock nut while depressing the brake pedal, disconnect the brake hydraulic line and parking brake cable, and separate the driveshaft from the knuckle. Remove all knuckle retaining bolts and nuts, making a match mark if necessary, then take out the knuckle and wheel bearings. To install, knock out the wheel bearing races from the knuckle, install the knuckle with wheel bearings to the driveshaft, reconnect the brake hydraulic line and parking brake cable, and install the wheel bearing lock nut. Finally, bleed the brakes and check the rear alignment. No adjustment is necessary for the Stanza Wagon 4WD, 240SX, and 1990-92 Stanza; ensure all parts are cleaned and apply multi-purpose grease sparingly to the spindle's rubbing surfaces. To adjust the bearings on 1982-86 Stanza models, raise the rear of the vehicle, remove the wheel, and bearing dust cap, then remove the cotter pin and retaining nut cap. Tighten the wheel bearing locknut to 29-33 ft. lbs. for 1982-86 models and 18-25 ft. lbs. for 1987-89 models, rotating the drum to seat the wheel bearing. For 1987-89 models, loosen the locknut to achieve zero preload, then torque to 6.5-8.7 ft. lbs., turning the wheel hub several times in both directions before re-torquing. For 1982-86 models, after turning the wheel, recheck the torque and then loosen it 90°. Install the retaining nut cap, align the cotter pin holes, and install a new cotter pin, bending up its ends before installing the dust cap.
