Attention! Dust generated during the normal operation of the brake system is harmful to health. Never blow it out with compressed air or inhale it. Always use a certified filter mask when working on brakes. Under no circumstances should you use petroleum-based solvents to clean the brake system. Use only brake cleaner!
Attention! If the vehicle is equipped with electronically controlled air suspension, turn off the suspension height control switch before raising the vehicle.
Note. The following procedure applies to two-wheel drive models only. On 4WD models, removing the hub and bearing from the rear hub carrier requires special tools and experience, so this job should be left to the professionals. However, the hub support and hub can be removed as a single unit and then contact the dealer's service department or another specialist workshop. For a description of how to remove the hub support and rear hub, refer to paragraph 14.
Note. The rear hub assembly with bearing is not serviced. If any element is found to be defective, it should be replaced by a single unit.
Removing
1. Loosen the wheel nuts, raise the vehicle and securely support it under it. Remove the wheel.
2. Remove the disc from the hub and disconnect the wheel speed sensor electrical connector (see chapter 9).
3. Remove the four bolts securing the hub to the hub support, providing access by rotating the hub so that the large circular cutout exposes each bolt in turn (pic. 13.3).
Pic. 13.3. To remove the four bolts that secure the hub/bearing assembly to the rear hub support, rotate the hub flange and align one of the holes in the flange with each of the bolts
4. Remove the hub assembly with the bearing from its original place, leading it through the parking brake assembly.
Installation
5. Install the hub assembly with the bearing on the hub support and align the holes in the brake shield. Install bolts. A magnet will be helpful when guiding the bolts into place through the hub flange. After installing all four bolts, tighten them to the specified torque specified in Specifications at the beginning of this chapter.
6. Install disc and caliper. Install the wheel. Lower the vehicle and tighten the wheel nuts to the specified torque specified in Specifications at the beginning of this chapter.
