• Q: How to Service and Repair the Control Arm in a Front Suspension System on 2004 Scion xA?

  A: The replacement process of the lower No.1 LH front suspension arm sub-assembly starts with front wheel removal together with the hood sub-assembly and engine assembly suspension. The separation process for the lower suspension arm from the steering knuckle requires tool 09628-00011 and removal of the clip and nut. The same procedure also works to detach the lower No.1 RH front suspension arm. Hold the front stabilizer bolt with a spanner to remove its nut followed by taking out the 2 retainers along with the cushion until extracting the front stabilizer bolt and repeating the same procedure on the other side. The power steering link assembly removal requires discarding its 4 bolts and 4 nuts before installing suspension hooks. You should disconnect the pressure feed tube assembly through bolt removal. Disconnect the front suspension member reinforcement LH and RH through removal of two bolts from each part. The front suspension crossmember sub-assembly can be separated through bolt removal followed by 2 nut removal then supporting it with a jack before taking out 4 bolts. Detach the front suspension arm sub-assembly lower No.1 LH unit by removing 2 screws and a nut but do not rotate the nut. The procedure for front suspension arm sub-assembly lower No.1 LH requires testers to first oscillate the ball joint stud five times before using a torque wrench to tighten the nut to 5.0 Nm (51 kgf-cm, 44 inch lbs.) or less. The technicians can tighten the front suspension arm sub-assembly lower No.1 LH with 2 bolts and a nut as a temporary measure. Use Special Service Tool: 09670-00010 to position the holes and install the front suspension crossmember sub-assembly using four bolts while tightening Bolt A to 70 Nm (715 kgf-cm, 52 ft. lbs.) followed by Bond B to 116 Nm (1,180 kgf-cm, 86 ft. lbs.) and finally adding a bolt and 2 nuts with 80 Nm (816 kgf-cm, 59 ft. lbs.). The front suspension member reinforcement LH and RH requires installation with 2 bolts per side while tightening to 47 Nm (480 kgf-cm, 35 ft. lbs.). The power steering link assembly requires installation of 4 bolts and 4 nuts while maintaining 74 Nm (755 kgf-cm, 55 ft. lbs.) torque but never rotate the nuts. Begin by installing the 2 retainers and cushion for the front stabilizer bar and keep the front stabilizer bolt stable with a spanner, then tighten the nut to 18 Nm (180 kgf-cm, 13 ft. lbs.) while using a jack to support the lower arm, do the same on the other side. Connect the lower suspension arm to the steering knuckle by installing a nut which should be tightened to 98 Nm (1,000 kgf-cm, 72 ft. lbs.) before installing a new clip while making nut adjustments if required. Finish the connection of the lower No.1 RH arm and install the front wheels with a torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.) while simultaneously fully tightening the front suspension arm sub-assembly lower No.1 LH with two bolts to 88 Nm (900 kgf-cm, 65 ft. lbs.) for Bolt A and 132 Nm (1,350 kgf-cm, 97 ft. lbs.) for Bolt B and avoid rotating the nut. Complete the installation of the hood sub-assembly by inspecting it and performing adjustments and check the front wheel alignment for adjustments.
