Question 1

How to service and repair the rear Wheel hub and Wheel Bearing on Toyota RAV4?

Accepted Answer

The repair and service operation for rear wheel hub and bearing involves starting with rear wheel removal followed by disconnecting the rear drive shaft assembly LH when servicing 4WD vehicles. The first step includes removing both the rear disc brake cylinder assembly LH as well as the rear disc. The dial indicator shows that measurements for bearing backlash should not exceed 0.05 mm (0.0020 inch) maximum and 0.08 mm (0.0031 inch) maximum for 2WD but 0.06 mm (0.0024 inch) maximum for 4WD. The disc replacement or rear wheel hub repositioning will be necessary when the runout measurement surpasses the maximum value. A replacement of the hub and bearing assembly should be conducted to address enduring problems. First disconnect the negative battery cable before waiting for ninety seconds to avoid Air Bag deployment. After that remove the four-wheel-drive shaft nut using Special Service Tool: 09930-00010 and strike it with a hammer to unstake it. The technician should start by removing the rear disc brake cylinder assembly LH, rear disc, skid control sensor wire for 2WD, and rear speed sensor LH for 4WD, and the rear suspension No. 1 arm assembly LH, followed by disconnecting the rear shock absorber assembly LH. Uninstall the rear wheel hub and bearing assembly LH from the axle carrier by disconnecting the bolts then position it so the magnet rotor remains upward. Attach the wheel hub and bearing assembly to the axle carrier through 4 bolts while torquing them to 90 Nm (918 kgf-cm, 68 ft. lbs.). Reconnect the rear shock absorber assembly LH with 2 bolts. The procedure requires first temporarily installing the rear suspension No. 1 arm assembly LH followed by the installation of skid control sensor wire for 2WD and rear speed sensor LH for 4WD and finally the rear disc and rear brake cylinder assembly LH. The installation of a new rear wheel shaft nut requires a torque of 216 Nm (2,203 kgf-cm, 159 ft. lbs.) followed by a chisel and hammer stake on the hub nut for 4WD systems. The last step includes installing the rear wheel while torquing it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Then stabilize the suspension before tightening the front shock absorber assembly LH and rear suspension No. 1 arm assembly LH. Followed by inspecting the rear wheel alignment and reconnecting the cable to the negative battery terminal and checking speed sensor signal.

Question 2

How to service and repair the front Wheel Hub on Toyota RAV4?

Accepted Answer

You need to take off the front wheel and empty automatic transaxle fluid before starting to work on the front wheel hub. To dissociate the cable from its battery connection you need 90 seconds before any Air Bags or safety features will react when you detach the negative terminal. Use Special Service Tool: 09930-00010 and a hammer to gently unfasten the LH hub bolt. Keep the drive shaft screw from getting harmed by loosening the nuts fully. During braking apply force then uncover the lock hub wheel nut before taking off the left-hand wheel speed sensor, left-hand Brake Cylinder and left-hand front disc. Detach the tie rod end and front suspension No. 1 lower arm sub-assemblies LH by removing the bolt, two nuts and disconnecting it from the ball joint. Separate the steering knuckle from wheel hub through two bolt and two nut removal plus shock absorber detachment. Label drive shaft and wheel hub positioning then strike the assembly gently to remove without wrecking the boot and speed sensor rotor. Through correct bolt unscrewing use the steering knuckle to take out both front lower ball joint assembly LH and front wheel hub sub-assembly LH. Keep the hub away from direct contact with foreign matter and ensure the magnet rotor side does not face downward. Finally, separate the dust cover from the steering knuckle. First put on the dust cover to the steering knuckle then place the wheel hub using four bolts at 71 ft. lbs. of torque (97 unit lbs) without damaging the magnet rotor side. You can install the left-hand front lower ball joint assembly and drive the drive shaft into its splines first. Then affix the steering knuckle and wheel hub with two bolts and two nuts before tightening them up to 240 Nm (2,447 kgf-cm, 177 ft. lbs.) without spinning the bolts. Fit the front suspension No. 1 lower arm sub-assembly LH to the ball joint and tighten using a bolt and two nuts at 92 Nm (938 kgf-cm, 68 ft. lbs.). Afterwards, connect the tie rod end sub-assembly LH and install the front speed sensor LH. Examine the front wheel hub bearing while simultaneously installing both the front disc assembly and front disc brake cylinder unit on the left-hand side. Set the new front wheel hub LH nut to 216 Nm (2,203 kgf-cm) for 2AZ-FE when using a 26mm socket and to 292 Nm (2,978 kgf-cm) for 2GR-FE with a 30mm socket. Use a chisel and hammer to stake the hub nut. Replace the automatic transaxle fluid then reattach the front wheel by tightening it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). After reviewing wheel alignment complete the battery connection and test the speed sensor function.
