• Q: How to Service and Repair the Axle Shaft Assembly on 2006 Toyota Sequoia?

  A: The first step for rear axle shaft assembly service and repair involves vehicle inspections which start with dial indicator measurements of the rear axle shaft bearing for shaft direction backlash to ensure the value does not exceed 0.6 mm (0.024 inch); a failed measurement requires bearing replacement. A replacement for the axle shaft is necessary if the deviation at the surface outside the hub bolt exceeds 0.1 mm (0.0040 inch). Begin by removing the rear wheel with a torque of 110 Nm (1,150 kgf-cm, 83 ft. lbs.). Then to proceed disconnect the brake line using Special Service Tool: 09023-00101 at 15.5 Nm (158 kgf-cm, 11 ft. lbs.). Afterward, remove the rear disc brake caliper assembly by taking out 2 bolts with 105 Nm (1,070 kgf-cm, 77 ft. lbs. torque). Repeat the inspection process of bearing backlash and axle shaft deviation according to the earlier method. The technician removes the parking brake assembly together with its 2 cable bolts that need a torque of 8.0 Nm (82 kgf-cm, 71 ft. lbs.) before repeating the sequence on the opposite side. Take off four nuts from the rear axle shaft assembly which should have a torque amount of 122 Nm (1,244 kgf-cm, 90 ft. lbs.) before you gently remove the assembly without harming the oil seal to finally extract the O-ring from the axle housing. The initial step for disassembly requires removing the rear axle bearing retainer inner before breaking off the speed sensor rotor by hammering off its serration bolts. Next, users should smooth the retainer and sensor rotor surfaces before prying them free. A snap ring expander should be used to extract the rear axle shaft snap ring while you install washers and attach nuts to serration bolts before tightening them and driving out the rear axle shaft together with a spring washer and bearing retainer using Special Service Tool: 09521-25011, 09521-25021. Research shows that you should utilize a brass bar to strike the brake drum oil deflector and remove its components which include six hub bolts and an oil deflector and a gasket. After this you can eliminate the rear axle bearing using hammer-operated serration bolt removal. The inspection of the rear axle shaft requires runout measurement for shaft and flange components to verify maximum shaft runout at 2.0 mm (0.079 inch) and maximum flange runout at 0.1 mm (0.0040 inch). Replace the rear axle shaft if it shows damage or if runout exceeds these boundaries. Installation of new oil seals demands Special Service Tool: 09308-00010 which allows you to remove the old oil seal before installation using Special Service Tool: 09950-60020 (09951-00730), 09950-70010 (09951-07150) and a hammer process. Complete the oil seal maintenance by applying MP grease to the lip of the seal. To install the rear axle bearing you should use a press along with 2 socket wrenches to fix the serration bolts as you position the backing plate on the bearing assembly. The new hub bolt requires a washer before tightening the nut to secure the newly installed gasket and oil deflector on the axle shaft. Use Special Service Tool: 09631-12090, 09950-60020 (09951-01030) and a press to install the rear axle shaft into the backing plate after setting the backing plate with spring washer and bearing retainer on the shaft. After using a snap ring expander to install a new snap ring proceed with the installation of a new speed sensor rotor along with a bearing retainer using these tools and ensure the standard length is 132.8 plus or minus 1.0 mm (5.228 plus or minus 0.039 inch). Completion of the procedure entails brake fluid filling in the reservoir followed by brake system bleeding and leak inspection then speed sensor signal check.
