COVERAGE TABLE ENDNOTES

12. These warranty terms cover units purchased and
serviced in the United States and Canada for line-haul,
On‑Highway service applications with a gross axle
weight rating up to 23,000 pounds. These applications
include auto haulers, vans, reefers, flatbeds and tank
trailers. Coverage may differ in some applications
where special written approval must be granted. Please
contact your Hendrickson sales associate to determine
if your application is warranted.

Some text within the COVERAGE TABLES include
superscript numbers which correspond to these
numbered paragraphs (refer to TRAILER APPLICATIONS
for trailer application definitions):
1.

Cambering an axle in the field voids the axle warranty.

2.

Axles that are drilled for a tire inflation system
(Hendrickson or otherwise) that do not follow
Hendrickson’s recommended drilling procedures
(as described in Hendrickson literature numbers
T51002 TIREMAAX® PRO &CP Installation, Service and
Troubleshooting, L995 TIREMAAX® CP Tire Inflation
System Installation, Service and Troubleshooting
Procedures or L818, TIREMAAX® Tire Inflation System Installation, Service and Troubleshooting Procedures)
could void the axle warranty. Unrecommended drilling
could cause damage to the axle or other suspension
components. Refer to page 8 through page 11
for additional information.

3.

Refers to Hendrickson suspension models when used
in Trailer Applications (see Appendix B on page 24)
in accordance with Hendrickson literature number
L707 Hendrickson Application Guide.

4.

For non pre-aligned suspension systems, the
installation and final assembly of the suspension pivot
connection is performed by the respective trailer OEM.
Refer to page 14 for further information.

5.

Includes suspension and slider components that
are not specifically covered in this table and are
manufactured and distributed by and for Hendrickson.

6.

For highway use only in 49 inch closed-spaced tandem
applications on van- and reefer-type trailers.

7.

For all Vocational trailers, single-axle, wide-spread
and tridem sliders, specialty and spread-axle vans, dry
freight van or refer-type trailers and trailers with liftable
axle suspensions.

13. The seven year parts and labor warranty terms apply
to all On‑Highway applications, (except auto hauler
application). The warranty coverage for HXL7® hub
assemblies in Off‑Highway application is three
years parts and labor. The HXL7 is not approved for
auto hauler applications. When equipped, the TIREMAAX
integrated rotary union and its hubcap carry the seven
year parts and labor warranty.
14. Competitor tire inflation systems are not covered by
Hendrickson warranty terms. Contact the respective tire
inflation system manufacturer for warranty coverage of
competitor make and model.
15. Hendrickson does not provide warranty coverage for
the installation, performance or components of a
competitor brand tire inflation system installed on a
Hendrickson suspension. Any consequential damages
to the Hendrickson suspension resulting from a
failure to the competitor brand tire inflation system
or components, whether installed by the OEM, repair
facility or end-user customer, should be directed to
the respective tire inflation system manufacturer for
warranty coverage. TIREMAAX is the only approved
tire inflation system to be installed with a wheel-end
installed by Hendrickson and compatible with the
wheel-end applicable warranty coverage.
16. Installation must be per published technical
procedures.
17. Includes all internal wheel-end / axle components,
including rotary union and tubing.

8.

The suppliers of these non-Hendrickson components
may offer warranty coverage beyond the terms listed
here. Contact the appropriate supplier for complete
details and continued warranty consideration.

18. Labor coverage applies only to Hendrickson installed
components (including but not limited to axle vent line,
axle hoses, spindle plugs, air control lines and beam
grommets).

9.

Refer to page 14 for further information.

19. Brake wear is influenced by many factors; operators,
tractor to trailer balance, application (city, flat, hilly
or mountains), environmental contamination, use of
hand operated trailer brakes, aerodynamics additions,
engine size, vehicle and load weight, the use of engine
brakes; to name a few. Due to these and other potential
variables and the influence they may have on product
performance, Hendrickson does not warrant the life
cycle, or service life, of drum brake linings or disc brake
pads.

10. The three year parts and labor warranty terms apply to
all On‑Highway applications. To be eligible for warranty
coverage in any Off‑Highway application, HXL3® hub
assemblies must be configured with HP spindles and
Hendrickson dust shields. When properly configured, the
warranty terms are one year parts and labor.
11. The five year parts and labor warranty terms apply to
all On‑Highway applications. To be eligible for warranty
coverage in any Off‑Highway application, HXL5® hub
assemblies must be configured with HP spindles and
Hendrickson dust shields. When properly configured,
the warranty terms are three years parts and labor.
When equipped, the TIREMAAX hubcap mounted rotary
union and its hubcap carry the five year parts and labor
warranty.

ADDITIONAL WARRANTY COVERAGE
INFORMATION

and spacing recommendations in various installation
drawings.

This section includes additional warranty information
relative to the items listed below.

Hendrickson does not recommend additional alignment
adjustments by the dealer or distributor prior to delivery
to the final customer (i.e., fleet, owner operator) and will
not reimburse for any related parts or labor expenses
from such additional adjustments. Hendrickson warrants
the perpendicularity and parallelism of the axles
relative to the slider box itself, based on established
Hendrickson specifications, only until delivery of the prealigned slider suspension system to the trailer OEM.

QUIK-ALIGN® PIVOT ASSEMBLY

Original equipment manufacturers (OEMs) have the
option of ordering Hendrickson suspensions in one of
two states: pre-aligned (available only on VANTRAAX® or
ULTRAA-K® slider suspension systems) or standard (non
pre-aligned - available on all Hendrickson suspension
systems). In either state, the pivot connection is
warranted for one year parts and labor. The difference is
in application and is as follows:

If a performance concern is expressed by the customer
regarding a pre-aligned slider suspension system,
the customer or trailer OEM dealer should CONTACT
HENDRICKSON prior to performing any adjustments or
repairs. Hendrickson will guide and provide assistance
to the customer, dealer and/or repair facility through
validation checks and will provide corrective actions as
necessary.

Hendrickson’s pre-aligned pivot connection warranty
applies to all QUIK-ALIGN® pivot assemblies
since installation and final assembly of the pivot
connection is performed by Hendrickson.
Hendrickson’s standard (non pre-aligned) pivot
connection warranty coverage applies only to QUIKALIGN pivot assemblies where proper installation and
final assembly were performed. The installation and
final assembly of the suspension pivot connection
is performed by the respective trailer OEM. Proper
installation includes, but is not limited to, the use and
removal of the Torx® head of the pivot bolt to ensure
proper pivot assembly torque along with the proper
mounting of the alignment washers/collars (refer
to Hendrickson literature numbers L577 HT/HS/HK
Installation Procedures and L579 Alignment Procedures
for additional assembly requirements). Pivot assembly
components must be available for review for warranty
consideration. Pivot assemblies that are missing the
plastic band or other reuse indicator, on the pivot bolt
hardware are not covered.

AIR DISC BRAKE WARRANTY STATEMENT

Hendrickson MAXX22T™ trailer air disc brake systems
installed by Hendrickson will carry a limited parts and
labor warranty, excluding all normal wear (Refer to
page 8). Other air disc brake packages installed
by Hendrickson will carry a limited one-year parts and
labor warranty, excluding all normal wear.
Hendrickson offers air disc brakes with our standard
service and HXL RTR® READY-TO-ROLL® wheel-end
packages. In order to maintain the integrity of
the wheel-end warranty, customers must contact
Hendrickson Technical Services prior to performing
maintenance on any air disc brake components and/or
the wheel-end assembly.
Component supplier additional warranty coverages
related to either ADB components or hub assembly
packages will be administered direct with the customer
by the respective component supplier.

PRE-ALIGNED VANTRAAX® OR ULTRAA-K®
WARRANTY STATEMENT

Pre-aligned slider systems are built on precision
fixtures and feature axles that are perpendicular to
the slider box and parallel to each other. Documented
measurement data confirms alignment and is shipped
with each slider suspension system built with this
option.
The trailer OEM is responsible for the total trailer
alignment and all facets of construction required to
accommodate the slider suspension system, such as
trailer frame construction, proper placement of the
kingpin, proper body rail installation and proper body
rail spacing. Hendrickson provides body rail installation
