Topic: Dana LMS™ Hub Assembly Procedure – Steer and Drive Axles
Note: Bulletin ABIB-0302 replaces the original bulletin ABIB-9606.
The Dana LMS™ hub design eliminates bearing adjustment and variables that cause excessive endplay leading to premature wheel seal failures.
The Dana LMS™ hub design combines proven seal technology with precision-manufactured bearing spacers and special tolerance bearings.
The Dana LMS™ Hub is available on the following Steer and Drive Axle Models:
Steer Axles:
E-1000I E-1202I E-1462I
E-1200I E-1460I E-1320I
Drive Axles:
All “R” series spindles only.
WARRANTY COVERAGE
Installation of the LMS™ Hub requires certification by Dana. The Dana LMS™ Hub is covered for 3 years/350,000 miles for On/ Off-Highway applications, when installation is performed by certified installers, and Dana approved synthetic lubes are used.
CAUTION: The wheel seal cannot be reused. Any time the hub is removed from the spindle, the seal must be replaced. Failure to follow this requirement will void warranty.
WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

PARTS INFORMATION
IMPORTANT: This is a pre-adjusted wheel hub and bearing system. Components required are a special tight tolerance hub, bearing spacer, bearings, oil bath seal, three or four-piece dowel-type nut system and identification tag.
Note: Purchase Genuine replacement Hub and Cup Assemblies through O.E.M.
Note: A special installation tool to hold outer bearing cone in place during assembly to spindle is recommended. This also helps prevent cocking of the wheel seal that may occur during installation.
WARNING: LMS™ hub components are made to special tight tolerances. Installation and/or servicing with other components will either create excessive endplay or cause excessive pre-load, reducing bearing and seal performance. Wheel separation may also occur.

INSTALLATION PROCEDURE
The following service procedures apply to the wheel end assemblies of the Dana steer and drive axle models listed. Follow these service and assembly procedures carefully to obtain proper wheel bearing adjustment and to increase service life.
WARNING: Never work under a vehicle supported by only a jack. Always support vehicle with jack stands. Block the wheels and make sure the vehicle will not roll before releasing the brakes.
IMPORTANT: Wheel seals can be easily damaged during handling. Leave the seal in its package until installation to prevent damage or contamination.
LMS™ HUB ASSEMBLY BUILD UP PROCEDURES:
1.Inspect/Clean the hub cavity, spacer, and bearing bores for any contaminants.
Important: Lubricate the wheel seal, and inner and outer bearing cones with the same lubricant used in the axle sump for drive wheel ends or lubricant to be used in hub for steer axles.
CAUTION: When using an oil bath system, do not pack the bearings with grease. Grease will prevent the proper circulation of axle lubricant and may cause wheel seal failure.
CAUTION: For steer axle hubs, install the bearing spacer into the hub assembly with large diameter end facing the inner bearing cup. This must be done before bearing and seal are installed.
2.With hub or wheel end assembly placed in a flat position, lubricate the inner bearing and install cone into the inner cup of the hub. (see Figure 1)
3.Place the seal on installation tool facing the proper direction. (see Figure 2)
Note: Do not apply any bore sealant to seal O.D. or I.D.
WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

CAUTION: The use of improper seal installation tools can distort or damage the seal, cause premature seal failure and void the warranty.
4.Position seal in hub bore. Tap adapter plate around outer edge to position seal. (see Figure 3)
5.Hit tool handle gently. Because of rubber O.D., some seals install much easier than metal O.D. type seals. Once the seal bottoms out in the hub, the seal is installed correctly. Check to be sure the seal is not “cocked” and that unitized seal I.D. and inner bearing turn freely. (see Figure 4)
6.Lubricate I.D. of seal with a light film of clean wheel end lubricant.
7.For drive axle, install the bearing spacer into the hub assembly, large diameter end against the inner bearing cone.
8.Lubricate the outer bearing cone and install into the outer cup of the hub assembly.
9.Install an approved installation tool to the hub cap mounting surface of the hub assembly with two existing nuts/studs or bolts. Hand tighten the nuts/bolts until the installation tool presses against the outer bearing cone. (see Figure 5)
10. The LMS™ Hub assembly is complete and ready for installation on the spindle.
CAUTION: Failure to use all required LMS components will increase wheel endplay and reduce seal performance.
WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.
