LMS Wheel End - Verify Wheel End-play
Attempts to measure wheel end-play of the completed
LMS hub system may result in false readings. If end-play
measurements are attempted, use a precision dial indicator.
Apply a strong push on the hub while rotating the hub back
and forth. Work the hub until the dial indicator shows no
additional movement. Then apply a strong pull while rotating
the hub back and forth. Work the hub until the dial indicator
shows no additional movement. Endplay measurements
greater than .005" may indicate a need to verify the correct
components were used and the spindle nut was installed
per the specifications.
Note: Wheel end-play and spindle nut torque should be
checked every 12 months.
LMS Wheel End - Lubrication
Before operating the axle, the wheel hub cavities and bear-
ings must be lubricated to prevent failure. When wheel
ends are serviced, follow Dana’s wheel end lubrication pro-
cedure before operating the axle.
For LMS Steer Axles
Lubrication fill - Oil type wheel ends
Note: Wheel hub configurations vary, allowing different
amounts of oil to be added depending on design. Allow
for the oil to seep through the outer bearing and fill the
hub cavity.
Note: During this fill operation, do not allow the oil to go
above the centerline or weep hole. This may result in a
weeping condition that may be perceived as a leaking
hubcap. Continue to add oil until the oil reaches the oil
level line as indicated on the hubcap.
Center Fill Port
1. Hub mating surface must be free of dirt, burrs, and
radial score lines.
2. Hub mating surface, hubcap flange, and gasket
should not be greased or oiled.
3. Always install and reinstall a hubcap with a new gas-
ket.
4. Install the hubcap and tighten hubcap bolts to the
specified torque.
5. Fill the hubcap through the center fill port to the
proper level (between add and full).
6. Rotate the hub several times then verify the lube is at
the proper level. Use only Dana approved synthetic
lube.
Side Fill Port
1. Fill wheel end assembly through side fill port with
the specified grade of oil
2. Install side fill hubcap plug and torque to 15- 25 lbs.
in.
3. Clean up any overspills that would give the appear-
ance of a leaky hubcap.
Lubrication fill - Semi-fluid wheel ends
1. Fill the hub cavity until the lube exits at the 3 o’clock
and 9 o’clock positions of the outer bearing. This
represents a 50% hub cavity fill.
2. Coat the spindle nut and spindle with lube.
3. Place 2 oz. of lube on the inner surface of the hubcap.
4. Hub mating surface must be free of dirt, burrs, and
radial score lines.
5. Hub mating surface, hubcap flange, and gasket
should not be greased or oiled.
6. Always install and reinstall a hubcap with a new gas -
ket.
7. Install the hubcap and tighten hubcap bolts to the
specified torque.
