Hub & Bearing Assembly, Rear Axle, Driver Side

The proper integration of the skid control sensor requires confirmation before installing the rear axle hub and bearing assembly because an entire hub assembly replacement becomes essential when the sensor needs replacement. The sensor rotor gets replaced at the same time when the customer decides to replace their complete rear axle hub and bearing assembly. Inspection of the installed rear axle hub bearing for looseness should be followed by a measurement of the rear axle hub runout. Install the rear disc along with the rear disc brake caliper assembly after completing this part of the process. Attach the connector to the sensor in order to connect the skid control sensor wire. Complete the installation by putting on the rear wheel then torque it to 103 Nm (1,050 kgf-cm, 76 ft-lbf) and inspect and adjust the rear wheel alignment. Moreover it is essential to verify that the speed sensor signal operates correctly.

Start rear wheel hub bearing and rear wheel hub bearing service by disconnecting the rear wheel and taking apart the rear disc brake caliper assembly LH while removing both the bolt and flexible hose from the shock absorber and detaching the two caliper assembly bolts. Employ a dial indicator to check rear wheel hub bearing looseness near its center with a 0.05 mm (0.0020 in.) maximum tolerance. The dial indicator must be directly perpendicular to the measurement surface. Replace the wheel hub assembly if the measurement exceeds the specified limit. The rear wheel hub runout should be checked on the surface outside the bolt with a maximum tolerance of 0.07 mm (0.0027 in.). This measurement requires a perpendicular alignment of the dial indicator. Replacing the wheel hub assembly is necessary when runout limits are exceeded. The repair requires reinstallation of the rear disc followed by tightening the two bolts securing the rear disc brake caliper assembly LH at 62 N m (632 kgf cm, 46 ft. lbf). Also avoid twisting the brake hose during installation. Installation of the rear flexible hose needs a torque setting of 19 N m (192 kgf cm, 14 ft. lbf). To finish the installation process replace the rear wheel while applying a torque of 103 N m (1,050 kgf cm, 76 ft. lbf) along with verifying proper connection of the ABS speed sensor signal. The removal and installation processes for the RH side mirror the steps already observed on the LH side. The installer should first secure the four bolts on the rear wheel hub & bearing assembly LH at 80 N m (816 kgf cm, 59 ft. lbf) torque before properly connecting the skid control sensor without twisting the wire.

The replacement of the rear wheel bearing begins with disc caliper brake assembly detachment including a bolt removal to separate the flexible hose and subsequent removal of two brake caliper retaining bolts. The first task requires disconnecting the flexible hose by unbolting the bolt and removing both brake caliper bolts on the left side wheel while maintaining proper support of the brake caliper assembly. Reduce the rear disc [42431 / 98-63] and separate the skid control sensor wire [89516 / 98-170] by disconnecting the connector. You must remove the left side rear axle hub and bearing assembly [42450B / 98-63] by extracting its four bolts and subsequent removal of the axle hub. First remove the existing skid control sensor [89544 / 98-170] before adding a new sensor of the same model [89544 / 98-170]. Secure the left side rear axle hub and bearing assembly [42450B / 98-63] with four bolts which should be torqued to 80 Nm (816 kgf-cm, 59 ft. lbs.). Resume the skid control sensor wire operation by attaching its connector [89516 / 98-170]. The bearing backlash inspection requires a dial indicator near the center of the axle hub which must not exceed 0.05 mm (0.0020 inch) maximum; when the value surpasses this threshold a new axle hub assembly must be installed. A dial indicator should check the axle hub deviation at the surface outside the hub bolt, and replacement of the axle hub assembly is necessary when the measurement exceeds 0.07 mm (0.0028 inch). Place the rear disc [42431 / 98-63] before setting the rear disc brake caliper assembly to the left side and tighten both bolts to 61.8 Nm (630 kgf-cm, 46 ft. lbs.) before securing the flexible hose with a bolt torqued to 29.4Nm (300 kgf-cm, 22 ft. lbs.). After reinstalling the rear wheel users should torque it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Then they should perform wheel alignment checks followed by ABS speed sensor signal assessment.

The first step to replace the Rear Wheel Hub & Bearing Assembly LH is to take off the rear wheel. Disassemble the rear disc brake caliper by breaking the bolt securing the flexible hose and then removing the two brake caliper securing bolts while securely supporting the caliper. The following step requires disc removal while also unconnecting the speed sensor wire through its connector. Move on to the removal of the rear wheel hub assembly through bolt extraction of the four attachments. The new wheel hub will be installed while tightening its four bolts to 80 Nm (816 kgf-cm, 59 ft. lbs.) torque setting. Secure the speed sensor wire connection through its connector plug. To check the bearing backlash, place a dial indicator at the hub center and ensure the backlash remains under 0.05 mm (0.0020 inch) or replace the wheel hub assembly. The wheel hub must be replaced if the dial indicator readings from the hub bolt surface outside measurement reach 0.07 mm (0.0028 inch). Reinstall the rear disc brake caliper assembly by fastening its two bolts to 61.8 Nm (630 kgf-cm, 46 ft. lbs.) torque and connecting the flexible hose directly afterward with a torque of 19 Nm (194 kgf-cm, 14 ft. lbs.). Finish by reattaching the rear wheel with 103 Nm torque and check the ABS speed sensor signal while inspecting and adjusting the rear wheel alignment.
