Toyota Celica/Supra 1971-1985 Repair Guide

Lower Control Arm and Ball Joints

Print

INSPECTION



  1. Raise the car so that all the weight has been removed from the front wheels.
  2.  
  3. Apply upward and downward pressure to the outer end of the lower control arm. Be careful to avoid any compression of the coil spring.
  4.  
  5. There should be no noticeable play between the bottom of the strut assembly and the ball joint. If play exists, the ball joint will require replacement.
  6.  

The ball joints on all Toyotas are permanently connected to the lower control arms. If either of them go bad, they must be replaced as a unit.

  1. Remove the two bolts holding the steering knuckle to the bottom of the strut tube. Pull the lower control arm down and disconnect the strut from the steering knuckle arm.

  5. Use a two armed gear puller and pull the arm off of the ball joint (tie rod on 1982 and later).
  6.  
  7. Remove the nuts holding the stabilizer bar and the strut bar to the lower control arm and position them both out of the way.

  9. Unscrew the bolt that attaches the control arm to the front cross member and remove the control arm.
  10.  
  11. Installation is in the reverse order of removal. The control arm-to-crossmember bolt is not tightened until last. After all other bolts have been tightened, tighten the bolt to 51-65 ft. lbs. (69-88 Nm). Tighten the stabilizer bar bolt to 11-15 ft. lbs. (15-20 Nm). Tighten the strut bar bolt to 29-39 ft. lbs. (39-53 Nm). Tighten the steering knuckle bolt to 51-65 ft. lbs. (69-88 Nm).
