Front Measurement

Lift up front end of vehicle under the control arms as close to the ball joints as possible. See Fig 1 . Check for play or looseness in the steering gear or tie rods, the wheel bearings, the upper spring strut mountings and control arm ball joints and bushings. If there is play in any of the above components, it must be corrected before an alignment can be performed.
Set up and calibrate test equipment according to manufacturer's instructions. Position the turntables under the front wheels. Use turntables which take up lateral movement. The car must stand level when the front wheels are on the turntables. Bounce the front suspension heavily a few times when the car has sunk onto the turntables.
Check the camber angle on both sides. Check measurement against specification. See WHEEL ALIGNMENT SPECIFICATIONS . If the front camber angle is not within specifications, adjust as needed. See CAMBER ADJUSTMENT .
