Adapter and the Beam Torque Wrench, turn the
input shaft.

NOTE

* Measure the preload at the same steering
rack center point.

* Make sure that the oil ports are not
plugged with caps. A plugged oil port will
affect the preload torque measurement.

To find the rack center point: the rack must
have a preload measurement of 45° in either
side of the center point for accurate reading. The
center point of the rack is 495° from right or left
lock. To reach the starting point of measurement,
turn the rack to either left or right lock, then turn 1 | Center Location of Steering Rack
