SOME VEHICLE APPLICATIONS, SUCH AS VEHICLES EQUIPPED WITH OUTRIGGERS, RETAIN SOME AIR
PRESSURE IN THE AIR SPRINGS AT ALL TIMES. PRIOR TO PERFORMING ANY MAINTENANCE, SERVICE,
OR REPAIR OF THE SUSPENSION, VERIFY EACH AIR SPRING IS COMPLETELY DEFLATED. FAILURE TO
DO SO COULD RESULT SERIOUS PROPERTY DAMAGE AND/OR SEVERE PERSONAL INJURY.
SERVICE HINT
Each frame hanger will have a pair of QUIK-ALIGN collars. Any eccentric (with the square drive
feature) QUIK-ALIGN collar should be mounted on the outboard side of the frame hanger. Axle thrust
angles can only be corrected on frame hangers equipped with eccentric QUIK-ALIGN collars.
SERVICE HINT
Mark the position of the QUIK-ALIGN square drive in relationship to the frame hanger with a paint
stick prior to loosening the QUIK-ALIGN connection. This will facilitate the axle alignment process
after the repair is complete.
6. Remove and discard the QUIK-ALIGN fasteners and collars, see Figure 8-41. The collars may
be reused if they are not damaged.

SERVICE HINT
Note the quantity of shims removed to maintain the correct pinion angle of the axle at assembly.
See Alignment & Adjustments Section of this publication.
7. Remove the fasteners and shim (if equipped) that attach the longitudinal torque rod to the
frame hanger.
8. Remove the fasteners that attach the frame hanger to the vehicle per vehicle manufac-
turer’s specifications.
9. Remove the frame hanger.
10. Inspect mounting surface for any damage or wear, replace as necessary.
11. Inspect the QUIK-ALIGN pivot bushing and torque rod bushings for wear or damage, replace
as necessary.
ASSEMBLY
1. Slide the new frame hanger over the support beam QUIK-ALIGN bushing.
2. Install the new fasteners that attach the frame hanger to the vehicle and tighten per vehicle
manufacturer’s specifications.
DISCARD USED QUIK-ALIGN FASTENERS. ALWAYS USE NEW QUIK-ALIGN FASTENERS TO COMPLETE
A REPAIR. FAILURE TO DO SO COULD RESULT IN FAILURE OF THE PART, OR MATING COMPONENTS,
LOSS OF VEHICLE CONTROL, PERSONAL INJURY, OR PROPERTY DAMAGE.
DO NOT ASSEMBLE QUIK-ALIGN JOINT WITHOUT THE PROPER FASTENERS. USE ONLY HENDRICKSON
GENUINE FASTENERS WITH SPECIAL COATING (H-COAT) TO SUSTAIN PROPER CLAMP FORCE. FAILURE
TO DO SO CAN CAUSE LOSS OF VEHICLE CONTROL, PROPERTY DAMAGE OR PERSONAL INJURY AND
VOID WARRANTY. ENSURE THAT THE QUIK-ALIGN FASTENER’S TORQUE VALUES ARE SUSTAINED AS
RECOMMENDED IN THE TORQUE SPECIFICATIONS SECTION OF THIS PUBLICATION. FAILURE TO DO SO
CAN CAUSE LOSS OF VEHICLE CONTROL RESULTING IN PERSONAL INJURY OR PROPERTY DAMAGE.
NOTE
Use a new support beam QUIK-ALIGN Bolt Kit (see Parts Lists Section of this publication) for
any axle alignment or disassembly of the QUIK-ALIGN connection. This ensures that the proper
clamp load is applied to the connections, so that the joints will not slip in service.
