Important Notes
1.
The following optional components are approved by this Guideline. All options may not be available on every axle model.
a.
Driver-Controlled Differential Lock
b. Oil Pump
c. Low Maintenance Wheel Ends (
2.
The use of
differentials in any drive axles will result in the exclusion of
from warranty consideration.
Certain other carrier components may also be excluded from warranty consideration if their failure is deemed to be the result
of NoSPIN use. Depending on axle loading, the NoSPIN can cause all torque to be directed to one axle shaft resulting in
overload and potential failure. “NoSPIN

3.
Drive Axle application approval and allowable gross axle weight is based on the vehicle suspension selected. Dana CVP is
not responsible for the durability of any bracket attached to the axle housing(s) unless produced by Dana Holding
Corporation. In addition, Dana CVP is responsible for the integrity of the bracket attachment only if the bracket is installed
by Dana or if the bracket is installed by the vehicle manufacturer following detailed recommended procedures provided by
Dana through prior agreement.
4.
For certain suspension models, Dana may require the use of an increased housing wall thickness. Refer to the Housing
Structural Rating Section of this Guideline or contact Dana CVP Application Engineering for specific requirements.
5.
It is the responsibility of the vehicle manufacturer and/or the dealer to accurately convey all approved axle loading
information to the body builder if the chassis is sold as incomplete. It is also the responsibility of the final vehicle builder to
insure the assigned tagged values for
do not exceed those limits approved by this vocational
Guideline. Dana is not responsible for non-compliance to this request.
6.
In vehicles equipped with
, the wheel speed mismatch between the front and rear axles is a concern. This
mismatch is affected by the front and rear axle ratio as well as tire revolutions per mile (TRPM). The % of mismatch
calculation is:
% mismatch = (Rear axle ratio x rear axle tire TRPM) - (front drive axle ratio x front tire TRPM)
Rear axle ratio x rear tire TRPM
Dana CVP Application Engineering requires this mismatch not exceed 1.5% for application approval.
7.
and/or
axles, if used, should comply with the
. When loaded, vehicles with
are limited to a 5 MPH speed maximum when operating with these axles in the raised position at the job site. Refer to the
Housing Structural Rating Section for maximum allowable
ratings.
8.
Drive axles configured with single tires and
outset wheels
that increase track over standard require special consideration.
Allowable gross axle weight ratings may have to be reduced from the nominal rating to compensate for the increase in
housing stress created through the use of outset wheels. Refer to the Housing Structural Rating Section of this Guideline for
additional information regarding increased track ratings.
9.
Oil pump and
Driver Controlled Wheel Differential Lock(s)
are recommended for Construction operations where vehicles
operate in areas of poor traction. The use of differential lock at speeds higher than 25 mph is not recommended by Dana. The
OEM is responsible for displaying in-cab information citing that the handling characteristics may be compromised when the
diff lock is engaged.
10.
For
equipped vehicles, the allowable gross axle load is to be equally distributed on all three axles. The use of liftable
or load reducing suspensions is not permitted.
11.
Vehicle testing of any nature voids the warranty on Spicer

drive axles.
