• Q: How to service and repair the front control arm on 2003 Toyota MR2 Spyder?

  A: The first step to repair or service the front control arm includes removing the front wheel followed by the stabilizer bar link through stabilization bar disconnect after the nut removal. If the ball joint moves when you remove the nut then hold the stud with a 5 mm hexagon wrench. Moving on with the work you should take out both brake caliper and disc bolts but keep the caliper safely supported as you proceed. You should disconnect the ABS speed sensor connector and remove the front axle hub assembly by removing its 4 bolts and its dust cover. The lower suspension arm detachment from the steering knuckle starts with removing the cotter pin plus the nut before utilizing Special Service Tool: 09628-62011 to handle the mechanical arm. To avoid turning the nut during removal, disconnect the front lower suspension arm and suspension member brace along with the 4 bolts and nut. Use a torque wrench to measure turning torque of the ball joint and install the nut after checking its rotation condition by flipping the stud 5 times. Between 0.59 Nm and 3.43 Nm is the suitable range for turning torque (6 - 35 kgf-cm, 5.2 - 30 inch lbs.). The procedure for new lower suspension arm installation requires the use of Special Service Tool: 09710-26011 (09710-05061) with a wooden block and press to install a new washer. The lower suspension arm and suspension member brace need to be mounted with all 4 bolts and nut before torque can be applied to bolt A (73 Nm, 745 kgf-cm, 54 ft. lbs.), B (87 Nm, 887 kgf-cm, 64 ft. lbs.) and C (75 Nm, 765 kgf-cm, 55 ft. lbs.). Do not rotate the nut during this process. Finish installing the lower suspension arm to the steering knuckle with its nut while torquing to 98 Nm (1,000 kgf-cm, 72 ft. lbs.). After that, insert a new cotter pin and adjust the nut angle up to 60 degrees if the holes need realignment. After wrapping the axle hub with the 4 bolts, apply torque of 56 Nm (571 kg.f.cm, 41 ft. lbs.). Complete the procedure by reconnecting the ABS speed sensor connector. Before installing the disc with brake caliper using its 2 bolts, torque the bolts to 109 Nm (1,112 kgf-cm, 80 ft. lbs.) then use the stabilizer bar link to secure the lower suspension arm with 3 retainers and 2 cushions using the nut at 18 Nm (184 kgf-cm, 13 ft. lbs.) before connecting the stabilizer bar link to the stabilizer bar through the nut with 44 Nm (449 kgf-cm, 32 ft. lbs.) torque and do this operation using a 5 mm hexagon wrench when needed The front wheel needs installation after torqueing it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.).
