Cars up to 9/89, issue. and all models "station wagon" (not all-wheel drive)
1. Change the position of the wheel disk relative to the hub so that the balanced wheel can be installed in its previous position.
2. Loosen the wheel nuts of the car on the ground.
3. Raise the car.
4. Remove the wheel.
5. Remove the hub cap with a screwdriver without damaging it.
6. Bend the bent collar of the nut so that the nut can be rotated.
7. Unscrew the hub nut and replace with a new one.
Attention! The hub nut on the left side of the car has a left-hand thread, to loosen it you need to turn it to the right (clockwise).
8. Screw on the hub nut by hand until it is snug. Then tighten the nut with a torque wrench 25 Nm.
Attention! Rotate the brake drum while tightening the nut so as not to pinch the hub bearing.
9. Rotate the hub several times to properly seat the bearing.
10. Slightly loosen the hub nut until it turns by hand.
11. Adjustment method without dynamometer: Lightly tighten the hub nut again while turning the hub. The brake drum should rotate easily, but there should be no noticeable side play. If there is play, check it with a dial indicator, see Section Wheel bearing check.
12. In MAZDA workshops, the hub bearing is adjusted as follows. (In practice, with some experience, the adjustment described above is sufficient):
- With the wheel bearing loose, install a dynamometer at a right angle on one of the wheel bolts.
- Pull on the dynamometer until the hub begins to turn. The force when the hub starts to rotate depends on the stuffing box. Take and record readings.
- Slowly tighten the hub nut while rotating the hub until the correct tension is achieved. Required value is 2.6 - 8.5 N. To it should be added the previously measured value of the gland resistance.
- With a correctly adjusted bearing, the torque at which the hub begins to rotate is 0,15 — 0.49 Nm.
13. Hammer the shoulder of the hub nut into the groove of the trunnion with a not very sharp chisel. This serves to protect against loosening of the nut.
14. Score new hub cap with pipe.
Attention! Deformed caps must be replaced, because due to leaks, moisture can get into the hub bearing and destroy it in a short time.
15. Screw on the wheel, taking into account the marking on the hub. Lower the vehicle and tighten the wheel nuts crosswise with force 100 Nm.
