1. Pull the trailer in a straight line for a sufficient distance
to ensure there are no binds in the suspension.
2. Disengage the trailer parking brakes and make sure the
trailer is empty.
3. Manually measure or use an optical device specifically
designed for alignment measuring to determine the
following:
a. Measure the distance from the king pin to the centerline
of the front axle spindles. It is recommended that
spindle extensions be utilized.
b. Dimensions A and B (Figure 20) must be equal to
within 1/8" (3 mm).
c. Measure the distance from the centerline of the front axle
spindles to the centerline of the rear axle spindles.
d. Dimensions C and D (Figure 20) must be equal to
within 1/16" (1 mm).

1. Using the measurements from Step 3, align each axle by
rotating the alignment bolt head on the front face of the
road-side frame bracket clockwise to move axle forward
(A arrows); counterclockwise to move axle rearward
(B arrows)
(Figure 21).
IMPORTANT: DO NOT loosen the pivot bolts.
IMPORTANT: Two (2) scribe lines on the side of the frame
bracket indicate maximum adjustment for
axle alignment. If the edge of the visible
washer touches either scribe line, the
SwingAlign™ axle alignment adjustment
is “out of stroke.” Inspect and repair trailer
components as necessary and realign.
(Figure 22).
IMPORTANT: The SwingAlign™ design maintains proper
alignment without welding or without
loosening of the pivot connection. DO
NOT weld alignment bolt or pivot bolts
(Figure 22). If connection requires
tightening, see decal XL-AR436 shown
in Section 2 of this manual.
