• Q: How to Service and Repair the Rear Axle Shaft on 2007 Toyota Sequoia?

  A: An on-vehicle inspection starts by checking rear axle shaft bearing backlash with a dial indicator in the bearing shaft direction; the measurement should not exceed 0.6 mm (0.024 inch) or the bearing needs replacement. The surface of the axle shaft outside the hub bolt requires minimum deviation of 0.1 mm (0.0040 inch) while the axle shaft needs replacement if this tolerance is exceeded. To access the rear wheel and brake components the technician should first loosen the wheel nut to 110 Nm (1,150 kgf-cm 83 ft lbs) before using Special Service Tool: 09023-00101 to disconnect the brake line with 15.5 Nm (158 kgf-cm 11 ft lbs) torque and unlatching the rear disc brake caliper assembly with its 2 bolts tightened to 105 Nm (1,070 kgf-cm 77 ft lbs). Aerospace Industry Standard assessments of bearing backlash and axle shaft deviation should be performed in accordance with the earlier description. The parking brake assembly should be removed along with its 2 bolts to extract the parking brake cable from the backing plate. This needs to be done with a torque of 8.0 Nm (82 kgf-cm, 71 ft. lbs.) before moving to the second side for the same procedures. The procedure for the rear axle shaft assembly includes changing four nuts with 122 Nm (1,244 kgf-cm, 90 ft. lbs.) of torque and extracting the shaft assembly gently without harming the oil seal before removing the O-ring from the housing. To disassemble the rear axle bearing retainer inner requires removing 4 speed sensor rotor nuts that attach to serration bolts before using a hammer to detach them. Afterward, the surfaces must be ground smooth using sandpaper before removing them with a chisel and hammer. Operation begins with a snap ring expander to remove the rear axle shaft snap ring after which you should attach washers and nuts to the serration bolts and torque the nuts and employ Special Service Tool: 09521-25011, 09521-25021 with a press to extract the rear axle shaft, spring washer, and bearing retainer from the backing plate before tool removal. To extract the brake drum oil deflector users must apply a brass bar and strike it with a hammer to pull out the 6 hub bolts with the oil deflector and gasket before detaching the rear axle bearing by screwing on 4 nuts to the serration bolts and hammering them off. The mechanic must test the rear axle shaft for flange and shaft runout before replacing it with new components if damage is detected or runout measurements exceed 2.0 mm (0.079 inch) and 0.1 mm (0.0040 inch). Use Special Service Tools 09308-00010 together with 09950-60020 (09951-00730), 09950-70010 (09951-07150) supported by a hammer to replace the oil seal utilizing MP grease on the new seal lip. To install the rear axle bearing you must position the backing plate on the bearing assembly while using a press fitted with two socket wrenches to tighten the serrated bolts. Apply the brake drum oil deflector on the axle shaft with a new gasket along with an oil deflector before securing it through a nut and bolt with a washer to a new hub bolt. The rear axle shaft assembly requires the backing plate and spring washer and bearing retainer mounted onto the shaft before inserting the axle with Special Service Tool 09631-12090, 09950-60020 (09951-01030) and a press. A new snap ring should be installed through the use of a snap ring expander followed by ABS speed sensor rotor installation with Special Service Tool: 09631-12090, 09950-60020 (09951-01030) and a press which should result in a standard length of 132.8 plus or minus 1.0 mm (5.228 plus or minus 0.039 inch). During installation the process works in the opposite direction of removal. After installation complete the procedure by filling brake fluid into the brake reservoir and bleeding the system followed by leak checking and speed sensor signal verification.
