  Q: How to remove the front lower Control Arm on Scion xB?

  A:

  Start the front lower suspension arm removal process by taking off both front wheels and then removing the No. 1 engine under cover and No. 2 engine under cover and finalizing with both rear engine under covers (LH and RH). The front lower No. 1 suspension arm sub-assembly bolts (LH and RH) should only be loosened while maintaining the nuts in their original position since each nut possesses its own stopper. The process of removing the front lower No. 1 suspension arm sub-assembly LH for manual transaxle requires disconnection of the 2 bolts and nut for completion. Front wheels should be aligned in a straight direction before you lock down the steering wheel. Processing requires removal of the column hole cover silencer sheet then separation of both the No. 2 steering intermediate shaft assembly and the No. 1 steering column hole cover sub-assembly. The first step consists of using hexagon wrenches (size 6mm if required) to remove front stabilizer link assembly nuts for both left (LH) and right (RH) sides. The next step consists of unfastening tie rod end sub-assemblies (LH and RH) before removing front suspension member reinforcements (LH and RH) through their four bolts. Separate the front suspension member brace rear with 3 bolts on the LH side while applying the same approach to the RH side. The front suspension crossmember requires a transmission jack for support before you disconnect the 4 bolts and 2 nuts on all manual and automatic transaxle systems. For automatic transaxles separate the front lower No. 1 suspension arm sub-assemblies (LH and RH) by unfastening their 2 bolts and single nut yet avoid rotating the nuts.

  Q: How to install the front lower Control Arms on Scion xB?

  A:

  First install 2 bolts and a nut for each side onto the front lower No. 1 suspension arm sub-assembly RH and LH. Keep the nut from turning because it features a built-in stopper. The operation takes place on a level front suspension crossmember. The transmission jack maintains the front suspension crossmember as you insert Special Service Tool: : 09670-00020 into its reference holes on both front suspension crossmember sides. Tighten all six components (2 bolts A, 2 bolts B, 2 nuts) on each side according to the specified torque values: Bolt A - 145 Nm (1479 kgf-cm, 107 ft-lbf), Bolt B - 95 Nm (969 kgf-cm, 70 ft-lbf), Nut - 95 Nm (969 kgf-cm, 70 ft-lbf). First tighten the 3 bolts on the front suspension member brace rear LH to specifications of A - 145 Nm (1479 kgf-cm, 107 ft-lbf) and B - 93 Nm (948 kgf-cm, 69 ft-lbf) before completing the same operation with the front suspension member brace rear RH. Insert the front suspension member reinforcement LH and RH with 4 bolts each at 96 Nm (979 kgf-cm, 71 ft-lbf) torque but first tighten bolts A and B temporarily before securing them in sequence with C, B, D, and A. The front lower No. 1 suspension arm sub-assembly LH for manual transaxle needs 2 bolts and a nut where the nut must stay untightened. Install the sub-assemblies of front lower No. 1 suspension arm in both LH and RH positions before connecting the sub-assemblies of tie rod ends and front stabilizer link assemblies LH and RH using a torque of 74 Nm (755 kgf-cm, 55 ft-lbf). If needed, use a hexagon wrench (6mm) to complete the installation. Install the front wheels while tightening the engine under covers, column hole cover silencer sheet and No.1 steering column hole cover sub-assembly along with the No.2 steering intermediate shaft assembly at 103 Nm (1050 kgf-cm, 76 ft-lbf) torque. The front lower No. 1 suspension arm sub-assembly needs full tightening using Special Service Tool: : 09961-01270 on bolt A to 172 Nm (1755 kgf-cm, 127 ft-lbf) torque or reach 233 Nm (2376 kgf-cm, 172 ft-lbf) torque without the tool while avoiding bolt rotation. Complete the bolt B torquing sequence to 233 Nm (2376 kgf-cm, 172 ft-lbf). Afterward, perform an inspection of both front wheel alignment and if necessary, make adjustments.
