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
. Lock in place. Check that the scale is set
on zero.
7.
Move the trammel bar to the front of the tires
(see
), and adjust the scale end so that the
pointers line up with the scribe lines. See
8.
Read the toe-in from the scale, and compare it to
the toe-in specification in Group 33 of the
Heavy-Duty Trucks Service Manual
. If corrections
are needed, see Group 33 of the same manual
for instructions on adjusting the toe-in.

Checking
Eaton Axle Lubricant Level
Checking
CAUTION
Failure to keep the rear axle filled to the proper
level with the recommended lubricant can result in
rear axle damage.
1.
With the vehicle parked on level ground, apply
the parking brakes, and chock the tires.
2.
If the vehicle has just been driven, allow a few
minutes for the lubricant to settle.
3.
Clean the oil fill plug and area surrounding it,
then remove the plug from the fill hole (
) or
from the standpipe (if so equipped) installed in
the fill hole.
IMPORTANT: A lubricant level close enough to
be seen or touched is not sufficient. It must be
level with the bottom of the fill hole (
) or
top of the standpipe opening.
4.
Lubricant should be level with the bottom of the
fill hole (
) or with the top of the standpipe
opening. If low, check the axle for oil leaks, and
correct as needed. Add lubricant as required.
See
for recommended drive axle
lubricants.

5.
Install and tighten the fill plug 40 to 60 lbf·ft (54
to 81 N·m).
6.
On non-drive axles equipped with oil-lubricated
wheel bearings, check the lubricant level at the
wheels. If low, add the same lubricant specified
for the drive axle.
NOTE: When adding or checking lubricant of
non-drive axles, clean the hub cap and plug be-
fore removing the plug. This minimizes the pos-
sibility of dirt entering the assembly
7.
Remove the chocks from the tires.

Eaton Two-Speed-Axle Shift Unit
Oil Level
CAUTION
Failure to keep lubricant at the specified level
could cause damage to the axle shift unit.
1.
Clean the shift unit oil fill plug, and area sur-
rounding it. See
. Remove the fill plug.
2.
The lubricant level should be maintained at the
bottom of the fill hole. If low, add specified lubri-
cant.
CAUTION
Before adding additional lubricant, make sure of
the type currently in the shift unit. To prevent
component damage, do not mix engine oil with
automatic transmission fluid.
IMPORTANT: When vehicle operating tempera-
tures are above 0°F (–18°C), use SAE 10
heavy-duty engine oil, API service classification
SD (sulfated ash content must not exceed
1.85%). When vehicle operating temperatures
are below 0°F (–18°C), use one part kerosene
to three parts SAE 10 heavy-duty engine oil,
API service classification SD (sulfated ash con-
tent must not exceed 1.85%). This cold-weather
mixture can be safely used up to 32°F (0°C).
Commercially available automatic transmission
fluid may be used in place of SAE 10 engine oil.
Automatic transmission fluid can be used for all
temperatures; do not mix kerosene with it.
3.
Apply a small amount of Loctite
®
242, or equiva-
lent sealant, to the threads of the fill plug. Install
the fill plug finger-tight; then, using a wrench,
tighten it 1-1/2 turns past finger-tight.
Eaton Axle Breather Checking
Axle housing breathers (
) must remain un-
clogged. Whenever the axle lubricant level is
checked, be sure the axle breather is open. Check
more often under adverse operating conditions. If the
breather is plugged or damaged, clean or replace it
as needed.
Meritor Axle Lubricant Level
Checking
CAUTION
Failure to keep the rear axle filled to the proper
level with the recommended lubricant can result in
rear axle damage.
1.
With the vehicle parked on level ground, apply
the parking brakes, and chock the tires.
2.
Clean the fill plug in the side of the axle carrier,
and the area surrounding it. See
. Then
remove the plug.
NOTE: Some Meritor axles have a small tapped
and plugged hole near and below the housing
oil fill hole. This smaller hole is for a lubricant
temperature indicator only, and should not be
used as a fill or level hole.
3.
With the vehicle on level ground, lubricant should
be level with the bottom of the fill hole. If low,
check for oil leaks, correct as needed, then add
specified lubricant. See
for recom-
mended drive axle lubricants.
