verse torque rod inspection.
1. Chock the front wheels.
2. Lift and support the frame.
3. Lift and support the axles.
4. Remove the tires.
It is recommended that the suspension is at full rebound before installing the jack stands. This will
provide maximum clearance for removal and installation of suspension components.
If the is equipped with a fifth wheel, to ease in AR2 installation it may be necessary to remove the
fifth wheel and re-install after AR2 suspension installation is completed.
5. Mark the centerline of the old suspension on both sides of the frame.
6. Disconnect and remove the old suspension. Leave the walking beams installed, unless being
re-bushed.
1. Clean the frame rail from rust and debris.
2. Inspect the frame rail for any cracks or damage. Repair or replace as necessary.
3. Reference the schematic and lay out holes on the frame. Typically all holes are referenced
from the centerline of the front hanger, see Figure 9-1. If equipped with a non RT•RTE suspen-
sions, the holes will be referenced from the centerline of the cross member.
Prior to drilling any holes in the frame or cross member gusset it is recommended that the height
control valve and linkage be fitted for proper location within the confines of the chassis.
