2009 Toyota Sienna Coil Springs Parts Q&A

• Q: How to install the rear coil springs and associated components on 2009 Toyota Sienna?

  A: The first step in installing the rear coil spring requires the placement of the coil spring insulator upper LH on thecoil spring rear LH position. First secure a shop rug onto the rear axle beam assembly then install the coil spring rear LH component while making sure its lower end enters the spring lower seat gap. A second shop rug must be applied to the rear axle beam assembly. The installation requires you to hook the shock absorber assembly rear LH to the rear axle beam assembly under the stationary jack as you loosely tighten the nut. Procedures should be repeated to install the components on the RH side. Proceed with the following installation of flexible hose and clip for the rear brake tube No.2 before you torque the brake tube to the flexible hose using Special Service Tool: 09023-00101 to a specification of 15 Nm (153 kgf-cm, 11ft-lbf). Subsequently install the bolt with a torque of 8.0 Nm (82 kgf-cm, 71in-lbf). To secure rear brake tube No.1 on the right-hand side use Special Service Tool: 09023-00101 according to previous directions. Set parking brake cable assembly No.3 in position by using two bolts which should be fastened to the rear axle beam assembly then torqued to 8.0 Nm (82 kgf-cm, 71in-lbf) and repeat the procedure on parking brake cable assembly No.2 for the RH side. The installation of differential carrier assembly rear should be followed by rear drive shaft assembly LH with 4 washers and 4 nuts that require 56 Nm (571 kgf-cm, 41ft-lbf) torque along with repeated steps for the RH side. First install the propeller w/center bearing shaft assembly then secure the speed sensor rear LH and bolt with 8.0 Nm (82 kgf-cm, 71in-lbf) torque followed by repetition of the same procedure for the RH side. The skid control sensor wire installation requires connecting the sensor connector and bolting the bracket to the rear axle beam assembly while torquing to 8.0 Nm (82 kgf-cm, 71in-lbf). The same steps must be repeated for the RH side. It is necessary to install the exhaust pipe assembly tail followed by bleeding the brake lines and checking the brake fluid reservoir level. Qualified technicians should install the rear wheel and lower the vehicle before applying 103 Nm (1,050 kgf-cm, 76ft-lbf) torques. Finally, they should bounce the vehicle to achieve suspension stability. Fully tighten the shock absorber assembly rear LH by supporting the rear axle beam assembly with a jack if required to perform the installation. Load the rear compartment with approximately 90 kg (198 lb) if necessary, then check the shock absorber length is 234 mm (9.2 in.) for 2WD or 258 mm (10.2 in.) for 4WD and torque to 115 Nm (1,173 kgf-cm, 85ft-lbf). Obtain all shock absorber assembly rear RH tightening specifications from the same sequence. Secure the rear axle beam assembly while torquing the bolt to 135 Nm (1,377 kgf-cm, 100ft-lbf) and check that the bolt receives the torques instead of the nut and the vehicle height matches the fully tightened shock absorber level. Fasten the left and right rear floor No.2 crossmember braces with two bolts that require torquing up to 28 Nm (286 kgf-cm, 21ft-lbf). The fuel tank filler pipe protector should be secured with 2 bolts and 3 nuts while the 3 screws tighten the fuel tank filler hose cover into position and both must be torqued to 5.0 Nm (51 kgf-cm, 44in-lbf). Below the required steps include checking rear wheel alignment while performing inspections of the ABS speed sensor signal according to the system type between ABS with EBD system or ABS with EBD & BA & TRAC & VSC system.
