• Q: How to service and repair the rear axle shaft on 2007 Toyota 4Runner?

  A: Service and repair of the rear axle shaft starts with removing the rear wheel together with the rear speed sensor before separating the rear disc brake caliper assembly and disc component removal. Start by removing the parking brake shoe return tension spring and next follow with the removal of parking brake shoe strut compression spring and parking brake shoe strut and finally parking shoe. Before servicing the rear axle shaft with backing plate users must detach the 4 nuts along with the O-ring. The rear axle shaft oil seal can be extracted with the help of Special Service Tool: 09308-00010 while a snap ring expander should be used to remove the snap ring. Special Service Tools 09521-25011, 09521-25023 along with a press help in the removal of the rear axle shaft. Start disassembly by striking the 4 parking brake plate to rear axle housing bolts outer with a hammer until all nuts separate to restore with new nut parts and dismiss the use of former nuts because of wear. Use Special Service Tool: 09650-17011 to remove 6 hub bolts then replace the brake drum oil deflector along with its gasket followed by grinding the rear axle bearing inner race surface until it removes the rear axle bearing oil seal. Use a dial indicator to measure rear axle shaft runout which should not exceed 0.0591 in. (1.5 mm) for the shaft length while the flange should be under 0.0020 in. (0.05 mm). Replace all components displaying damage or wear. The reassembly process starts by positioning the deflector gasket followed by the deflector before passing the 6 bolts through the axle hub. Finally, tighten the hub nut. Start by mounting the rear axle hub and bearing assembly before placing the backing plate and securing the 4 parking brake plate to rear axle housing bolts through two socket wrenches within a press. Position the rear axle shaft washer and place a new rear axle bearing retainer inner inside. The installation process requires Special Service Tool: 09521-25011 along with a press to install the rear axle shaft before applying a new rear axle shaft snap ring with a snap ring expander. For the rear axle shaft setup use Special Service Tool: 09950-60020 (09951-00770), 09950-70010 (09951-07150) and a hammer to install a new oil seal before securing the shaft with backing plate and new O-ring and 4 nuts at 123 Nm (1,254 kgf/cm, 91 ft. lbs.). In this step install the parking brake shoe followed by the strut and compression spring before adding the return tension spring and rear disc. After that, connect the rear disc brake caliper assembly and rear speed sensor. After fluid addition to the reservoir, bleeding occurs for the master cylinder along with brake line and a final inspection includes brake fluid level checks as well as leak detection. Installation of the rear wheel requires a torque of 112 Nm (1,142 kgf/cm, 83 ft. lbs.) with an inspection of parking brake lever travel and ABS speed sensor signal adjustment.
