2009 Scion tC Parts Questions & Experts Answers

• Q: How to install the axle shaft assembly on the LH and RH sides on 2009 Scion tC?

  A: The installation procedure for LH front drive shaft assembly starts with gear oiling the inboard joint shaft spline followed by proper spline alignment before driving the shaft in using a brass bar assisted by a hammer to keep the snap ring opening pointed downward but protect oil seal and boot while guarding the dust cover from damage. The front drive shaft installation for the RH side requires gear oil coating of the spline followed by alignment before driving in the shaft with two bolts tightened to 64 Nm (650 kgf-cm, 47 ft-lbf). Move on by matching each mark before putting in the drive shaft to the front axle while ensuring protection for both the outboard joint boot and speed sensor rotor. The front No. 1 suspension lower arm sub-assembly needs the lower ball joint to be installed onto the suspension lower arm by using a bolt with 2 nuts and reaching a torque of 89 Nm (908 kgf-cm, 66 ft-lbf). Install a new nut to the tie rod end before mounting it to the steering knuckle where a final torque of 49 Nm (500 kgf-cm, 36 ft-lbf) should be achieved. After that, add a new cotter pin by tightening the nut 60 degrees to compensate for misalignment between holes. The speed sensor front needs installation to the steering knuckle using a bolt with 8.0 Nm (82 kgf-cm, 71 in-lbf) torque strength. Connect the speed sensor wire along with the flexible hose to the shock absorber through a bolt that should receive 19 Nm (194 kgf-cm, 14 ft-lbf) torque. Keep the speed sensor undamaged and prevent the attachment of foreign matter to the sensor. The installation of the front stabilizer link requires use of a 6 mm hexagon wrench to stabilize the ball joint while torquing its nut to 74 Nm (755 kgf-cm, 55 ft-lbf). Apply a non-residue solvent to wash threaded drive shaft and axle hub nut components before installing a new axle hub nut torqued to 216 Nm (2200 kgf-cm, 159 ft-lbf) then stake the nut by hammering on a chisel. The engine installation process requires front wheel torque of 103 Nm (1050 kgf-cm, 76 ft-lbf) with automatic transaxle fluid addition followed by fluid inspection adjustments before manual transaxle oil addition and front wheel alignment inspection and adjustment before checking the ABS speed sensor signal.
