ASSEMBLY
1. Clean the QUIK-ALIGN slots in the hangers and collars of any dirt and debris and inspect for
any wear or damage. Replace as necessary.
2. Prior to installing the U-beam assembly, verify the clamp group is tightened to the proper
torque.
THE WEIGHT OF THE U-BEAM ASSEMBLY IS APPROXIMATELY 225 POUNDS. CARE SHOULD BE TAKEN
AT REMOVAL AND INSTALLATION TO PREVENT PERSONAL INJURY OR DAMAGE TO COMPONENTS.
3. Install the U-beam assembly into the hangers.
DO NOT ASSEMBLE ANY QUIK-ALIGN JOINT WITHOUT THE PROPER FASTENERS. USE ONLY HENDRICKSON
COATED FASTENERS TO SUSTAIN THE 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 FASTENERS TORQUE VALUE IS SUSTAINED AS RECOMMENDED IN
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 new QUIK-ALIGN pivot bolt kit (see Parts List 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 connection, to ensure the joint will not slip in service.
4. Verify the correct QUIK-ALIGN collar (eccentric/concentric) is in the correct location as
noted in the disassembly procedure.
5. Install QUIK-ALIGN connection with new Hendrickson fasteners and snug to about
50-100
foot pounds torque, DO NOT tighten at this time. The final torque must be done after the
alignment is complete.
6. Position the U-beam assembly on a floor jack.
7. Raise the U-beam assembly until the D-pins engage in the bottom cap.
SERVICE HINT It may be necessary to rotate the QUIK-ALIGN eccentric collars to allow the full engagement of
the D-pins into the bottom caps.
SERVICE HINT It may be necessary to raise or lower the front of the differential to allow the D-pins to engage
in the bottom cap. Use a drift pin if necessary to align the D-pins with the bottom cap.
