secure each with the two bolts and washers. Torque the
bolts to 305 to 373 Nm (225 to 275 lb-ft).
4. Secure the four air bags to the carrier brackets with two
nuts and washers. Torque the nuts to 41 Nm (30 lb-ft).

nut, lockwasher, and hardened washers.
6. Secure the linkage rod of each height control valve to its
respective saddle
hardware.
7. Attach the fore and aft torque rods to the carrier frame
using two bolts and hardened washers each. Torque the
bolts 769 to 834 Nm (567 to 615 lb-ft).
8. Attach the lateral torque rods to the carrier frame using
two bolts, hardened washers, and nuts. Use additional
hardened washers between torque rod and bracket to
aid in properly centering axle.
9. Connect the drive shaft to the front rear axle.
10. Install the air fittings in the inlet of the air bags. Connect
the air lines to the air bags and brake chambers as
tagged during removal.

130 ± 10 psi.
2. Turn suspension inflation switch on.
3. Install digital level on bottom of frame rail above the
trailing arm and zero level.
4. Next set digital level on top of the trailing arm and adjust
the ride height until a reading of 0.0° ± 0.5° is achieved.
5. Repeat procedure on frame and trailing arm on the other
side of the frame.
6. Once all four corners are adjusted, drive the machine
forward at a slow speed and "tap" the brake pedal to
bounce the machine. Do this 3 times going forward, then
3 times in reverse.
7. Repeat steps 3 through 5 until all the trailing arms
remain adjusted within 0.5° of level.
