2006 Toyota Land Cruiser Parts Questions & Experts Answers

• Q: How to service and repair the front Wheel Hub on 2006 Toyota Land Cruiser?

  A: The front wheel hub service process starts by taking off the front wheel followed by the front disc brake cylinder followed by the front disc. The inspection must use a dial indicator to confirm axial hub clearance stays under 0.05 mm (0.0020 inch) and if exceeding the value the bearing needs to be replaced. The tool must be used to measure wheel hub deviation after which new bearings need replacing if measured values exceed the maximum limits. Perform removal by removing the front wheel first then disconnecting the flexible hose from the steering knuckle and supporting the brake cylinder after removing its bolts. Begin the front wheel hub outer shaft flange removal by disassembling the grease cap then the snap ring with subsequent removal of 6 nuts and washers. Keep these washers in place to protect the threads and then take out the flange and gasket. The procedure to take off the wheel hub with disc requires releasing the lock washer followed by using Special Service Tool: 09607-60020 to extract the lock nut and adjusting nut with caution to protect ABS speed sensor rotor components and oil seal integrity. Start the disassembly by using tools to remove the oil seal then take out the bearing followed by using a brass bar and hammer to tap out the races for inspection of all components to check for damage or wear. The process using Special Service Tools includes installing the front disc while aligning matchmarks and tightening the 5 bolts to 74 Nm (750 kgf-cm, 54 ft. lbs.). Moreover, install the new outer and inner bearing races following tool usage and avoid damaging the ABS speed sensor rotor. Apply abundant MP grease into the wheel hub bearing space before inserting the interior bearing inside the hub and covering the inside hub surface with grease. New oil seals should be tapped through Special Service Tool 09950-60020 (09951-01030), 09950-70010 (09951-07100) yet their lips must receive MP grease application. The installation requires the wheel hub with its disc to be placed on the steering knuckle followed by the outer bearing and claw washer installation. Adjust the preload through tightening the adjusting nut with Special Service Tool: 09607-60020 until it achieves a torque of 59 Nm (600 kgf-cm, 43 ft. lbs.) then perform several hub rotations followed by loosening the nut until it becomes hand-rotatable before retightening it to 4.3 to 6.5 Nm (44 to 66 kgf-cm, 38 to 57 inch lbs.). Check for any looseness. Assembly requires new lock washer installation then installing the lock nut and torquing the lock nut to 64 Nm (650 kgf-cm, 47 ft. lbs.) then checking for proper hub functionality and correct preload readings. After applying the new gasket to the wheel hub, assemble the components by placing the flange followed by six cone washers, six washers, and six new nuts in the specified sequence while torquing to 33 Nm (335 kgf-cm, 24 ft. lbs.). Verify a snap ring clearance under 0.2 mm (0.008 inch) before installing a new snap ring combined with the grease cap. Complete the task by installing the brake caliper directly followed by applying torque to the caliper bolts at 123 Nm (1,250 kgf-cm, 91 ft. lbs.). Then secure the flexible hose to the steering knuckle using 28 Nm (290 kgf-cm, 21 ft. lbs.), install the front wheel at 131 Nm (1,340 kgf-cm, 97 ft. lbs.), and verify the ABS speed sensor signal.
