Adjust steer axle skew.
•
Raise the machine on outriggers and place an alignment turntable under each of
the steer tires.
Lower the machine making certain not to bottom-out the
turntables or put them in a bind.
•
Measure the distance between the “center hook” on the frame to the corner of the
front steer axle mount, left and right; each axle’s left and right measurements
should be within 3/16 in. (4.8 mm) of the other.

•
Adjust axle mounting shims to achieve squareness. Reposition the shim/s to the
front of the bar pin to move the axle forward, or to the back of the bar pin to move
the axle toward the rear. Slight adjustments might be achieved by adjusting
shims on one side of the axle. Larger adjustments will be achieved by adjusting
both sides in opposite directions. Re-torque hardware to 450-600 lbf*lb. (610-
813 N*m).
Note: Raise the machine on outriggers to take weight off the suspension in order to reposition
the mounting shims. A Porta Power can be used to support the suspension. Be sure to lift the
outriggers and put full weight on the suspension prior to taking subsequent measurements.

Lower the machine to the ground. Back out and drive straight into the work area
several times to ensure the vehicle’s suspension components remain relaxed and
achieve proper measurements. Place wheel chocks on the drive axles.
