Removal and installation the rear hub assembly and wheel bearing (Opel Corsa C)

CORSA C models with drum brakes

Note: The function of the hub on these models is performed by the brake drum, into which the wheel bearing is pressed.

1. Remove the drum brake mechanism (see Chapter 9).

2. Remove the pulse sensor from the brake drum hub using the Opel-KM-161-B puller with removable hooks KM-161-3 and the KM-161-4 device (see accompanying illustration).



3. Remove the wheel bearing retaining ring from the drum hub using special pliers (see accompanying illustration).





4. Press the wheel bearing out of the brake drum with a hydraulic press using the Opel-KM-500-5 tool (see accompanying illustration).



5. Before installation, clean the drum hub and lubricate with bearing grease.

6. Installation is performed in the reverse order of removal. A special device KM-273 is used to install a new wheel bearing (see illustration 10.6a), and for the pulse sensor - the KM-6175 device (see illustration 10.6b).

9. Press the rubber grommet out of the brake shield and pull out the ABS sensor wiring harness. Separate the brake hose holder from the shield.

10. Slightly lift the corresponding trailing arm of the rear suspension with a jack and unscrew the lower shock absorber mounting bolt (see illustration 10.8)

11. Remove 4 mounting bolts (see accompanying illustration) and remove the hub assembly from the trailing arm.





12. Install the hub assembly and secure it with new bolts, tightening them finger tight. Then tighten the bolts to the required torque in 3 steps (see Specifications). When installing the assembly, it must be given the exact position it occupied before removal - to check the position at service stations, a special template Hazet 6690 is used, for individual use you can cut the template out of thick cardboard. At the first opportunity, check the wheel alignment angles at the service station.

13. Further installation is carried out in the reverse order of removal.
