Summary
Operation Name: Hendrickson Truck Commercial Vehicle Systems Document Name: Technical Procedure - SOFTEK Front Suspension System for Lion Bus Summary: This document provides preventive maintenance, service, repair and rebuild instructions for Hendrickson
SOFTEK front axle and suspension systems equipped on Lion Bus vehicles.
AXLE CAMBER IS NOT ADJUSTABLE. DO NOT CHANGE THE AXLE CAMBER ANGLE OR BEND THE
AXLE BEAM. BENDING THE AXLE BEAM TO CHANGE THE CAMBER ANGLE CAN DAMAGE THE AXLE AND
REDUCE AXLE STRENGTH, AND WILL VOID HENDRICKSON’S WARRANTY. A BENT AXLE BEAM CAN
CAUSE LOSS OF VEHICLE CONTROL, POSSIBLY CAUSING PERSONAL INJURY OR PROPERTY DAMAGE,
SEE FIGURE 8-10.
FIGURE 8-10
6. Check camber angle. DO NOT attempt to adjust camber. Refer to “Camber” under the
Alignment Definitions in this section.
7. It is necessary to verify that all ride heights (front and rear) are within specifications prior to
checking caster to get an accurate caster reading.
8. Check and adjust caster angle. Refer to Caster Angle under Alignment Definitions in this
section.
NOTE
The use of two (2) different angle caster shims will not change cross caster. Cross caster is the
difference between the caster readings for left and right side of the vehicle.
9. Check and adjust toe-in. Refer to Adjusting the Toe-In under Alignment Definitions in this
section.

STEERING STOP
ADJUSTMENT
When the axle or lower steering knuckle is replaced, the steering stop adjustment must be checked.
The steering stop adjustment procedure is as follows:
1. Drive truck onto turntables and chock the rear wheels.
2. Measure the wheel cut. The wheel cut is determined by steering the tires. Wheel cut is
measured at the inside wheel only, therefore the tires must be turned to the full lock position for each right hand and left hand direction. Refer to the vehicle manufacturer for exact
specifications.
3. Increase the wheel cut by loosening the jam nuts and screw the axle stops in clockwise.
4. Tighten the jam nuts.
5. Decrease the wheel cut by loosening the jam nuts and screw the axle stops out
counter-clockwise.
ALWAYS CHECK / RESET THE STEERING GEAR BOX POPPETS WHEN THE WHEEL CUT IS DECREASED.
FOLLOW MANUFACTURER’S GUIDELINES FOR THE GEAR BOX POPPET RESETTING PROCEDURE.
FAILURE TO DO SO CAN RESULT IN PREMATURE FAILURE OF THE AXLE OR STEERING KNUCKLE. THIS
CONDITION CAN CAUSE LOSS OF VEHICLE CONTROL, PERSONAL INJURY OR PROPERTY DAMAGE AND
VOID WARRANTY.
FIGURE 8-11
NOTE
It is very important that the sides of
the square head axle stops are set
parallel to the axle beam to ensure
a good contact point on the axle,
see Figure 8-11.
6. T i g h t e n t h e j a m n u t s t o
50 ± 10 foot pounds torque.
7. Measure the wheel cut and
check for any interference with
related steering components.
TOE SETTING
1. Place the vehicle on a level floor with the wheels in a straight ahead position.
2. Raise the vehicle and support the front axle with jack stands.
3. Use paint and mark the center area of tread on both steer axle tires around the complete
outer diameter of the tires.
4. Scribe a line through both steer axle tires in the painted area around the complete outer
diameter of the tires.
5. Raise the vehicle and remove the jack stands.
6. Set the vehicle on the ground.
NOTE
DO NOT measure toe-in with the front axle off the ground. The weight of the vehicle must be on the
front axle when toe-in is measured.
7. Use a trammel bar and measure the distance between the scribe marks at the rear of the
steer axle tires. Record the measurement.
8. Install the trammel bar and measure the distance between the scribe marks at the front of the
steer axle tires. Record the measurement, see Figure 8-12.
Alignment & Adjustments

17730-312
SOFTEK® for Lion Bus
NOTE
When setting up the trammel bar the pointers should be level with the spindles at the front and
rear of the steer axle tires.
9. To calculate the toe setting subtract the front measurement from the rear measurement, the
difference between the two will equal the toe-in / toe-out measurement.
FIGURE 8-12
10. If the toe measurement is not within the specifications of 1⁄16" ± 1⁄32"(0.06" ± 0.03"), it will be
necessary to adjust the toe setting. Refer to the following procedure.
a. Loosen the tie rod cross tube clamp bolts and locknuts.
b. Turn the tie rod cross tube until the specified toe-in distance is achieved.
THE THREADED PORTION OF THE TIE ROD END MUST EXTEND PAST THE SLOTS INTO THE TIE ROD CROSS
TUBE, SEE FIGURE 8-13. FAILURE TO DO SO CAN CAUSE COMPONENT TO FAIL CAUSING LOSS OF VEHICLE
CONTROL AND POSSIBLE PERSONAL INJURY OR PROPERTY DAMAGE.
c. Tighten the bolt and locknut on the tie rod cross tube to
68 ± 7 foot pounds torque.
11. Repeat Steps 1 through 9 until the correct toe setting is achieved.
FIGURE 8-13
5/8" Tie
Rod Clamp Bolt
It is critical to check the 5/8" tie rod clamp
bolt head location to verify the clamp
fasteners have sufficient clearance away
from the lower shock mount at full wheel
cut. The fasteners must not contact the
lower shock mount.
Tie Rod Cross Tube Slots
It is critical to have the threaded
portion of the tie rod end extend past
the slots in the tie rod cross tube.

bolt locknuts to 300 ± 10 foot pounds torque.
6. Affix a straight edge to the bottom of the frame rail
behind frame hanger, see Figure 8-15.
7. With the vehicle on a level surface measure the
distance from the top of the straight edge to the
ground on both sides of the vehicle and record the
measurements.
8. Measure the difference from one side to the other.
9. Do a road test and repeat measurement Steps 7
to 9.
10. If the measurement is less than 3⁄ 8" the vehicle
is level. If measurement is more than 3⁄8" contact

FASTENERS
Hendrickson recommends that when servicing the vehicle replace the removed fasteners with new
equivalent fasteners. Maintain correct torque values at all times. Check torque values as specified.
See Hendrickson’s Torque Specifications Section of this publication. If non-Hendrickson fasteners are
used follow torque specifications listed in the v ehicle manufacturer’s service manual.
SHOCK ABSORBER
NOTE
It is not necessary to replace the shock absorber in pairs if only one (1) shock absorber
requires replacement.
THE SHOCK ABSORBERS ARE THE REBOUND TRAVEL STOPS FOR THE SPRINGS. ANYTIME THE FRONT
AXLE ON AN SOFTEK SUSPENSION IS SUSPENDED IT IS MANDATORY THAT THE SHOCK ABSORBERS
REMAIN CONNECTED. FAILURE TO DO SO COULD CAUSE A REVERSE ARCH IN THE STEEL LEAF SPRINGS,
POSSIBLY RESULTING IN PREMATURE STEEL LEAF SPRING FAILURE.
DISASSEMBLY
1. Place the vehicle on a level floor.
2. Chock the wheels.
3. Remove and discard the lower shock absorber mounting bolts and fasteners.
4. Remove and discard the upper shock absorber mounting bolts and fasteners.
DO NOT GRAB THE SHOCK ABSORBER AS IT COULD POSSIBLY BE HOT AND CAUSE PERSONAL INJURY.
5. Slide out the shock absorber.
6. Remove the lower shock absorber spacer.
7. Inspect the shock absorber mounting brackets and hardware for damage or wear, replace as
necessary.
FIGURE 9-1
ASSEMBLY
1. Install the shock absorber into the upper mounting bracket.

DO NOT USE A CUTTING TORCH TO REMOVE CLAMP GROUP BOLTS OR ATTACHING FASTENERS. THE
USE OF SUCH HEAT ON SUSPENSION COMPONENTS CAN ADVERSELY AFFECT THE STRENGTH OF
THESE PARTS. A COMPONENT DAMAGED IN THIS MANNER CAN RESULT IN THE LOSS OF VEHICLE
CONTROL AND POSSIBLE PERSONAL INJURY OR PROPERTY DAMAGE.

50 foot pounds increments to 293 ± 12
foot pounds torque in the proper pattern to
achieve uniform bolt tension, see Figure 9-7.
11. Remove the frame supports and load the
front axle with the vehicle weight.
12. Tighten the M20 spring eye bolt locknuts to
300 ± 10 foot pounds torque.
FRONT LEAF SPRING EYE BUSHING
The spring eye bushings for the SOFTEK spring and wrap leaf assemblies are designed to provide
extended service life. If premature wear occurs careful consideration must be given to the contributing factor that caused the wear. This must be corrected in order to prevent the new bushing from
wearing in the same manner. The front and rear bushings are permanently installed in the spring
leaf and are not serviceable. If a bushing wears prematurely, the spring and wrap leaf assembly
must be replaced. Follow the procedure for the Front Leaf Spring removal in the Component
Replacement Section of this publication.
