33–03 Tie Rod Lubrication

Detroit and Meritor Axles

For any Detroit or Meritor axle that requires lubrica-
tion of the tie-rod ends, wipe the grease fittings
clean, then pump multipurpose chassis grease, NLGI
Grade 1 (6% 12-hydroxy lithium stearate grease) or
NLGI Grade 2 (8% 12-hydroxy lithium stearate
grease), into the tie-rod ends until all used grease is
forced out and fresh grease is seen at the ball stud
neck. See

33–04 All-Axle Alignment

Check

Drive Axle Alignment Checking

Check the axle alignment, parallelism, and thrust
angle measurements for the rear drive axles. Use the
applicable procedure and specifications in Group 35
of the Cascadia

Workshop Manual.

Toe-In Inspection

For vehicle alignment to be accurate, the shop floor
must be level in every direction. The turn plates for
the front wheels must rotate freely without friction,
and the alignment equipment must be calibrated
every three months by a qualified technician from the

equipment manufacturer. Freightliner dealers must
have proof of this calibration history.

1.

Apply the parking brakes and chock the rear
tires.

2.

Raise the front of the vehicle until the tires clear
the ground. Place safety stands under the axle.

3.

Using spray paint or a piece of chalk, mark the
entire center rib of each front tire.

4.

Place a scribe or pointed instrument against the
marked center rib of each tire, and turn the tires.
The scribe must be held 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 and lower the
vehicle. Remove the lock-pins from the gauges;
make sure the tires are exactly straight ahead.
On vehicles with rack and pinion steering, center
the rack using the pointers on the front of the
input shaft housing. See

Fig. 5

.

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, then for-
ward 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. 6

. Lock in place. Check that the scale is set

on zero.

7.

Place the trammel bar at the front of the tires
(see

Fig. 7

) and adjust the scale end so that the

pointers line up with the scribe lines. See

Fig. 8

.

8.

Read the toe-in from the scale, and compare it to
the toe-in specification in Group 33 of the Cas-
cadia

Workshop Manual. If corrections are

needed, refer to Group 33 of the Cascadia

Workshop Manual for instructions on adjusting
the toe-in.
