2006 Scion xB Parts Questions & Experts Answers

• Q: How do you service the rear coil spring on 2006 Scion xB?

  A: The service of rear coil springs requires rear wheel removal along with disconnection of the skid control sensor wire through connector removal followed by bolt removal to separate sensor wire from the axle beam on both sides. Use Special Service Tool: 09023-00101 to disconnect the rear No. 4 brake tube then remove its clip while noting that the clip should stay unused. The procedure to remove the rear No. 3 brake tube should be done in an identical manner. Disassemble both No. 3 and No. 2 parking brake cable assemblies by unwinding the nut and separating them from the axle beam. To assemble the rear axle beam use jacks to support both sides while disconnecting shock absorbers from the rear assembly of the left and right sides. Lower the jack until you successfully remove the LH rear coil spring together with its upper insulator as well as lower insulator. The installation begins by mounting the coil spring LH which must be fitted with the upper insulator gap at the end of the coil spring and then adding the lower insulator and coil spring to the axle beam while ensuring the paint mark stays below the vehicle body. Install the rear shock absorber assembly LH into the axle beam through temporary support using jacks and a washer and nut. Perform the same procedure on the right-hand side. Screw the No. 3 parking brake cable assembly with 5.4 Nm torque using 55 kgf-cm or 48 inch lbs. then repeat the cable connection of the No. 2. Use Special Service Tool: 09023-00101 to connect the rear No. 4 brake tube with a 15 Nm (155 kgf-cm, 11 ft. lbs.) torque while installing the clip followed by the same process on rear No. 3. Connect the skid control sensor wire by installing the bolt at a torque of 8.0 Nm (82 kgf-cm, 71 inch lbs.), also check the sensor wire connections. Adjust the shock absorber to stabilize the bolt during full tightening. When needed, use a jack to support the axle beam plus 90 kg (198 lbs.) weight in the the rear compartment before tightening to 82 Nm (836 kgf-cm, 60 ft. lbs.). Secure both rear shock absorber assembly bolts with 49 Nm (500 kgf-cm, 36 ft. lbs.) torque starting from the LH side followed by the RH side. Tighten the rear wheel with 1,050 kgf-cm torque (103 Nm; 76 ft.lbs.). Additionally test the speed sensor signal on ABS and align the rear wheel. Afterward bleed the brake line.
