b. Air Ride Suspension Axles
The air ride suspension is aligned and adjusted
at the factory and it should not be necessary to
align the axles. If, however it does become neces-
sary to align the axles, the procedure is as follows:
1.
To align air ride suspension axles, locate
the front axle equalizer beam pivot bolt in
front hanger at front end of lock nut. Loosen
the suspension pivot bolt lock nut. Rotate
the head of the pivot bolt. For axle
alignment forward, rotate bolt head
clockwise. For axle alignment rearward,
rotate the bolt head counter-clockwise.
Both sides of axle need to be adjusted to
prevent axle rise or fall.
2.
Align the front axle using the method
outlined in
Section 4-7.2 a.
3.
After proper alignment has been obtained,
tighten the suspension pivot bolt nut to the
torque listed in the table in
Section 4-6.1 b.
4.
Align the rear axle to the front axle. Locate
the rear axle equalizer beam pivot bolt in
hanger at front end of driver’s side rear axle
equalizer beam. Loosen the suspension
pivot bolt lock nut. Rotate the head of the
pivot bolt. For axle alignment forward,
rotate bolt head clockwise. For axle
alignment rearward, rotate the bolt head
counter-clockwise. The rear axle should be
parallel with the front axle, with the
dimensions Y and Y1 being the same.
5.
Tighten the suspension pivot bolt nut to the
torque listed in the table in
Section 4-6.1 b.
