• Q: How to install the Control Arm in the front suspension on 2008 Toyota Prius?

  A: The first step to install the front suspension lower No. 1 arm requires the attachment of the front suspension lower No. 1 arm sub-assembly LH to the suspension crossmember using 2 bolts and a nut with temporary tightening. Start with installing the front suspension crossmember sub-assembly and afterward attach the front drive shaft assembly LH and RH. Continue installation by adding the front axle assemblies LH followed by RH while keeping the right-hand side procedure identical to left-hand side installation. Use a bolt and 2 nuts to fasten the front suspension lower No. 1 arm sub-assembly LH to the front lower ball joint while torquing them to 89 Nm (908 kgf-cm, 66 ft-lbf). The installation of front suspension lower No. 1 arm sub-assembly RH also needs to be performed. The stabilizer link assembly connects to the front shock absorber with coil spring through nuts torqued to 74 Nm (755 kgf-cm, 55 ft-lbf). A 6mm hexagon wrench holds the stud if the ball joint rotates with the nut. After fitting the front axle hub nuts LH and RH, install the No. 2 tie rod end sub-assembly and the No. 1 tie rod end sub-assembly. The RH side installation follows the same sequence of steps used for the LH side. Attach the front wheel followed by torquing it to 103 Nm (1,050 kgf-cm, 76 ft-lbf) before installing the front exhaust pipe assembly. The suspension should be stabilized by letting the vehicle drop then performing multiple bounce movements. Establish the steering sliding yoke assembly before you install the column hole cover sheet for reduction of noise. The finishing step involves tightening the 2 bolts of the front suspension lower No. 1 arm sub-assembly LH to 137 Nm (1,400 kgf-cm, 101 ft-lbf) while preventing the nut from rotating during the process before dropping the tires to the floor using a 4-post lift. A necessary check of front wheel alignment will follow.
