• Q: How to install the rear differential carrier assembly on 2009 Toyota Sienna?

  A: Begin the rear differential carrier installation process by mounting the No. 1 rear differential support to the assembly using 2 bolts and 2 nuts which should be tightened to 85 Nm (867 kgf-cm, 63 ft-lbf). Keep holding the bolt during nut tightening procedures. You must assemble the rear differential support with a dynamic damper onto the No. 1 support by using two bolts and torquing them to 20 Nm (204 kgf-cm, 15 ft-lbf). After installing the three bolts onto the rear differential carrier assembly you must torque them to 100 Nm (1,020 kgf-cm, 74 ft-lbf). Install the rear differential carrier assembly by using two bolts which need torque application at 106 Nm (1,081 kgf-cm, 78 ft-lbf) and attach the No. 1 rear differential support using a bolt and nut at a torque of 95 Nm (969 kgf-cm, 70 ft-lbf). The rear drive shaft installation starts with the LH side although the RH procedure follows the same steps. The installation process for the rear axle shaft nut LH matches precisely with that of the RH side. You will follow up by installing the rear speed sensor LH where the installation on the RH side remains identical. Fully tighten the propeller with center bearing shaft assembly following its proper installation. The installation requires a 10 mm hexagon wrench for the rear differential drain plug with a new gasket and a final torque to 49 Nm (500 kgf-cm, 36 ft-lbf) before filling the rear differential carrier assembly with hypoid gear oil. After checking differential oil the technician should install the rear differential filler plug with a 10 mm hexagon wrench and also a new gasket which needs to be tightened to 49 Nm (500 kgf-cm, 36 ft-lbf). Proceed with the installation of the rear wheel before securing it to 103 Nm torque specifications (1,050 kgf-cm, 76 ft-lbf). Afterwards install the exhaust pipe assembly. The first step is exhaust gas inspection while the technician performs a rear wheel alignment check along with adjustment tasks. The last step should be an evaluation of the ABS speed sensor signal.
