HINT: For example, measure from the edge of a tire tread lug to the outboard side of the chassis, then repeat the measurement on the other side of vehicle using the exact same points.
If the two measurements are equal, the axle is centered. If the measurements vary, divide the difference in half to determine the amount of adjustment required. HINT: If the axle housing is not centered, the chassis can be laterally shifted using either of the following methods.
Ratchet Strap (preferred)
Attach a heavy duty ratchet strap to the chassis on one side of the vehicle, and to the axle housing on the other side.
Tighten the strap in small increments to pull the chassis in alignment with the axle.
Take measurements after each adjustmentuntil centered.
Have a partner turn the steering wheel in small increments to shift the vehicle chassis side-to-side.
After each adjustment, have your partner hold the steering wheel steady while you take measurements.
4. SET ADJUSTABLE TRACKBAR LENGTH AND MOUNT TO AXLE
IMPORTANT: The length of the Adjustable Trackbar must be set with axle housing perfectly centered and the vehicle at normal ride height.
With the axle housing centered beneath the chassis, adjust the length of Adjustable
Trackbar by rotating the axle end until the rubber bushing aligns with the mounting holes on the axle bracket.
Install Axle End (B) of Adjustable Trackbar to the axle bracket by securing with the original mounting bolt and flag nut. Apply anti-seize lubricant to bolt threads.
Take measurements again to ensure axle housing is perfectly centered and make any final adjustments if necessary.
Check the Chassis End (D) of Adjustable Trackbar to ensure it is aligned with the chassis rail bracket. If necessary, rotate fore/aft until the space between the trackbar and chassis rail bracket is even.
