Setting Ride Height
If your vehicle is equipped with a Peterbilt rear air suspen-
sion, you should ensure that the air springs are set at the
proper height. Incorrectly adjusted air spring heights may
result in improper interaxle U-joint working angles. This can
result in premature driveline wear and additional driveline
vibration. The proper ride height for the single-drive Low Air
Leaf suspension is 17.3 in. (440 mm) as shown.
Follow the procedure below to set the air spring height:
WARNING! Park the vehicle and chock the
wheels before beginning this procedure.
1. Ensure that the air supply and delivery plumbing of the
height control valve is consistent with the illustration.
2. Detach the link rod(s) from the control arm(s) by remov-
ing the 1/4-20 bolt (link bolt) that connects them.
