• Q: How to replace the FRONT CONTROL ARM SUB-ASSY LOWER NO.1 LH on 2004 Toyota Prius?

  A: The 1st LH lower FRONT Suspension Arm sub-assy requires replacement after users position the front wheels in a straight-ahead direction followed by removing the column hole cover silencer sheet. Start by dividing the steering sliding yoke sub-assy and remove the front wheel and the exhaust pipe assy from the front position. First remove the FRONT AXLE HUB LH NUT with Special Service Tool: 09930-00010 before moving on to the FRONT AXLE HUB RH NUT. The same procedures must be applied for the rh side. The next step involves the separation of the TIE ROD END SUB-ASSY LH with Special Service Tool: 09628-00011 then repeating this process for the TIE ROD END SUB-ASSY RH by following the same steps already applied to the LH side. To detach the front stabilizer link assy users must separate it from the front shock absorber with coil spring while holding the stud stationary with a hexagon (6 mm) wrench to prevent the ball joint from turning with the nut. To remove FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 LH you must first detach its bolt and two nuts before lowering it away from the front lower ball joint assy. Apply this procedure to FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 RH as well. Remove FRONT AXLE ASSY LH and FRONT AXLE ASSY RH by repeating previous procedures which were used for the RIGHT HAND side. To separate the FRONT DRIVE SHAFT ASSY LH and the FRONT DRIVE SHAFT ASSY RH use Special Service Tool: 09520-01010, 09520-24010 (09520-32040) based on procedures for the RH side. Use the hex wrenches to separate the FRONT SUSPENSION CROSSMEMBER SUB-ASSY and remove the FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 LH by loosening its two bolts and nut and maintaining nut rotation stability. Secure the FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 LH to the suspension crossmember sub-assy through the temporary installation of its two bolts and nut. Use Special Service Tool: 09670-00010 to mount the FRONT SUSPENSION CROSSMEMBER SUB-ASSY followed by FRONT DRIVE SHAFT ASSY LH and FRONT DRIVE SHAFT ASSY RH installations which require performing the same steps for the RH side. The installation of FRONT AXLE ASSY LH and FRONT AXLE ASSY RH will use identical methods as performed on the RIGHT HAND SIDE. Use the bolt and two nuts to secure the FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 LH to the front lower ball joint assy before applying torque of 89 Nm (908 kgf-cm, 66 ft. lbs.). The procedure is repeated for installation of the FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 RH. The FRONT STABILIZER LINK ASSY needs installation by attaching it to the front shock absorber with coil spring through nut torquing to 74 Nm (755 kgf-cm, 55 ft. lbs.) and requiring a hexagon (6 mm) wrench to stabilize the stud if needed. The installation procedure for TIE ROD END SUB-ASSY LH and TIE ROD END SUB-ASSY RH should follow the same methodology applied to the RH side. Fasten the FRONT AXLE HUB LH NUT while following exactly the same procedure for the RIGHT-HAND side hub nut. The front tire installation should be followed by vehicle lowering and bouncing to achieve suspension stability before the exhaust pipe front reinstallation. The technician should install the steering sliding yoke sub-assy along with the column hole cover silencer sheet. Tighten the two bolts at 137 Nm (1,400 kgf-cm, 101 ft. lbs.) on the FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 LH until the nut stops rotating and then use the 4-pillar lifter to lower the tires to the ground. Finish the task by checking and aligning the front wheel alignment.
