Removal and installation the wheel hub and steering knuckle (Mazda CX-5KE)

Note:

: replace the part with a new one after each removal.

: use a special tool or device.

: apply lubricant.

Removal the steering knuckle with the wheel hub

Caution: Performing the following procedure without first removing the front ABS wheel sensor may cause an accidental open circuit in the wiring harness. Disconnect the front ABS wheel sensor wiring harness before performing the following procedures (from the drive shaft side) and secure the wiring in a suitable location where it will not be accidentally touched when servicing the vehicle.

1. Loosen the mounting bolt and remove the front ABS wheel sensor.

2. Remove the brake hose clamp.

3. Loosen the drive shaft lock nut.



4. Install the spare nut onto the drive shaft threads so that the edge of the nut is flush with the end of the drive shaft.

5. Tap the nut with a brass hammer to knock the drive shaft out of the front wheel hub.

6. Disconnect the drive shaft from the wheel hub.

7. Remove the brake caliper assembly (see chapter "Brake system") and put it aside, hanging it on the car body with a wire.



8. Remove the brake disc (see chapter "Brake system").



9. Loosen the nut and disconnect the upper part of the anti-roll bar from the suspension strut.

10. Disconnect the steering rod end from the steering knuckle.

11. Disconnect the lower ball joint from the steering knuckle.

12. Loosen the bolts securing the front shock absorber to the steering knuckle and remove the steering knuckle assembly.

13. Loosen the bolts securing the wheel hub to the steering knuckle.

14. Remove the wheel hub and dust cover from the steering knuckle.

15. If necessary, use a press to remove the bolts from the wheel hub.

Note: Wheel hub bolts should only be removed for replacement.

Installing the steering knuckle with the wheel hub

Installation is carried out in the reverse order of removal, taking into account the following:

Installing wheel hub bolts

Use a press to install new wheel hub bolts.

Installing a wheel hub

Apply lubricant (L2Y1 33247) on the inner ring of the wheel bearing and the contact surface of the drive shaft (area A in the figure).

Installing wheel hub mounting bolts

Attention: Wheel hub mounting bolts are tightened to a certain angle, but do not reach the yield point (as is the case with cylinder head bolts). Therefore, there is no need to check the length of the bolts.

Installing the bolts securing the steering knuckle to the suspension strut

Install the steering knuckle on the front shock absorber and insert the bolts in the desired direction: on the right side of the car - from the front to the back, on the left side of the car - from the rear to the front. Then tighten the nuts to a torque of 222-245 Nm.

Tightening the drive shaft lock nut

After tightening the lock nut to a torque of 390 Nm, unscrew it by 180 degrees, then tighten it again to a torque of 236-274 Nm.

Note: After installation, check the wheel alignment angles and adjust if necessary.
