• Q: How to remove the control arm on 2003 Toyota Prius?

  A: The first step requires removal of the front wheel by using 103 Nm of torque force (1,050 kgf-cm, 76 ft. lbs.). The procedure starts with removing the engine under cover and lower suspension arm by using tools to disconnect the RH and LH tie rod ends at a torque of 49 Nm (500 kgf-cm, 36 ft. lbs.). After removing the cotter pin and nut users can disconnect the tie rod end from the steering knuckle with Special Service Tool: 09628-62011 and repeat the process for the other side. You must disconnect the stabilizer bar links of both sides by unscrewing the nut while using a 5 millimeter hexagon wrench to stabilize the stud when the ball joint turns with the nut. Both sides require this process. Next disconnect the RH and LH lower suspension arms from the bottom ball joints by taking out the bolt as well as 2 nuts while keeping the torque at 142 Nm (1,450 kgf-cm, 105 ft. lbs.) before moving to the other side. Tighten the 2 lower suspension arm set bolts to 137 Nm (1,397 kgf-cm, 101 ft. lbs.) but keep in mind to torque both bolts after stabilizing the suspension during installation. Dismantle the sliding yoke while using a transmission jack to hold the suspension member before removing the bolt and nut which disconnects the torque rod from the suspension member using 100 Nm of torque (1,150 kgf-cm, 83 ft. lbs.). To disconnect the suspension member from the body you must first remove the 4 bolts while torquing them to 113 Nm (1,152 kgf-cm, 83 ft. lbs.) on the front side and 157 Nm (1,600 kgf-cm, 116 ft. lbs.) on the rear side. After that remove the 2 lower suspension arm set bolts to detach the lower suspension arm from the suspension member. It is necessary to follow the opposite sequence of removal steps during installation while performing a front wheel alignment check.
