Propeller Shaft Universal Joints
Cross Type (No fittings) — Relubrication of this type of
universal joint is not required. The seals should be
inspected for external leaks or damage. If external leaks
or damage is evident, the universal joint should be
replaced.
Rear Axle Fluid Level
Refer to Fluids, Lubricants and Genuine Parts for the
correct Fluid type. For normal service, periodic fluid level
checks are not required. When the vehicle is serviced for
other reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is suspected
inspect the fluid level.
This inspection should be made with the vehicle in a level
position. The fluid level should be 3/4” ± 1/4” below the
plug on DANA M60 HD/248 mm rear axles.
Drain and Refill
Vehicles operated in normal service do not have regularly
scheduled oil changes. If fluid has become contaminated
with water or to provide the correct viscosity grade, drain
and refill.
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.
NOTE: The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
