33–02 Knuckle Pin Lubrication,
Meritor® Axles
NOTICE
Use regulated pressure when lubricating the
knuckle assemblies, otherwise damage could re-
sult to the knuckle caps.
Park the vehicle on a level surface, apply the parking
brakes, and chock the tires. When lubricating knuckle
pin bushings, do not raise the front axle. Wipe the
lube fittings clean, and apply multipurpose chassis
grease, NLGI Grade 2 (8% 12-hydroxy lithium stear-
ate grease), until new grease is seen at the bushing
grease seal opposite the fittings. The grease seal will
accept grease pressure without damage, and is de-
signed to have grease pumped out through it during
lubrication. Even if grease leaks out around the top,
or bottom-plate gasket, continue pumping until new
grease is seen at the bushing seal opposite the
grease fitting; see
NOTE: For operation in very cold climates, use
NLGI Grade 1 (6% 12-hydroxy lithium stearate
grease).
33–03 Tie Rod Inspection
1.
Park the vehicle on a level surface, apply the
parking brakes, and chock the tires.
2.
Check for a missing cotter pin or loose tie-rod
end nut. Tighten as needed. Install a cotter pin if
it is missing.
3.
Shake the cross-tube. A loose fit, or movement
between the tapered shaft of the ball and the
cross-tube socket members indicates that the
tie-rod end assembly must be replaced.
4.
The threaded portion of the tie-rod end assembly
must be inserted all the way into the cross-tube
split for adequate clamping; see
. Replace
the components if this cannot be done; see
Group 33
of the
122SD and Coronado Work-
shop Manual

Detroit and Dana Spicer
Axles
Detroit Axles
For any Detroit axle that requires lubrication 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.
