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.
