Hold the scribe firmly in place so that a single
straight line is scribed all the way around each
front tire.
5. Place a turn-plate or turntable under both front
tires. Remove the safety stands from underneath
the axle, then lower the vehicle. Remove the
lock-pins from the gauges; make sure that the
tires are pointing straight ahead.
NOTE: If turn-plates or turntables are not avail-
able, lower the vehicle. Remove the chocks
from the rear tires and release the parking
brakes. Move the vehicle backward and then
forward about six feet (two meters).
6. Place a trammel bar at the rear of the front tires;
locate the trammel pointers at spindle height,
and adjust the pointers to line up with the scribe
lines on the center ribs of the front tires. See
Fig. 5 . Lock the pointers in place. Check that the
scale is set to zero.
7. Place the trammel bar at the front of the tires
and adjust the scale end so that the pointers line
up with the scribe lines. See
Fig. 6 and Fig. 7 .
8. Read the toe-in from the scale, and compare it to
the toe-in specification in
Group 33 of the
Walk-In Van Chassis Workshop Manual , or take
the vehicle to an authorized Freightliner dealer. If
corrections are needed, see
Group 33 of the

WARNING
Be careful not to overfill the hubs. Overfilling may
cause oil to be forced out of the hubs and to con-
taminate the brake linings and other brake compo-
nents. This could result in loss of vehicle control
and lead to personal injury and property damage.
