CHECKING SPECIFICATIONS

(1) Manual or Power Steering
The caster specifications shown are with the frame level from front to rear. Measure front to rear frame angle when checking alignment and compensate as follows: If the front of the frame is lower than the rear, the actual caster angle is obtained by adding the frame angle to the caster angle as shown on the checking equipment. If the front of the frame is higher than the rest, subtract the frame angle from the caster angle shown on the checking equipment.

The following instructions are to be followed to assure a correct camber reading on F-100 thru 350 Twin-I-Beam truck models:

Install a spacer block between each frame side rail and its respective front axle I-beam to obtain the height shown in views A and B. Raise the frame or add weight to the front of the vehicle to make sure the side rails rest on the blocks.
The radius of both front tires must be equal within ⅛". Radius to be checked from center line of spindle to the ground.

(2) View B = 3½ inches

(3) View A - 4 inches

The following scans were taken from the 1967 factory shop manual, and show the proper tools and technique for cold-bending the I-beams to correct camber issues.
