1.

REMOVE ORIGINAL EQUIPMENT

(OE) FRONT TRACK BAR



Remove front track bar and mounting hardware

per the factory service manual instructions for

your vehicle.

HINT: If difficult to remove, use

universal puller tool to separate OE track bar ball

stud from chassis rail bracket.

‰

2. MOUNT ADJUSTABLE TRACKBAR TO

CHASSIS BRACKET



Using a 5/8” drill bit, enlarge the tapered mount-

ing hole in the chassis rail bracket located on the

driver-side of the vehicle.



Locate Chassis End (A) of Adjustable Trackbar

and insert the 5/8” x 4-1/2” Bolt (H) through the

Flex Joint Ball (K).



Apply anti-seize lubricant to bolt threads.



Mount chassis end of Adjustable Trackbar to chas-

sis rail bracket by inserting the



5/8” x 4-1/2” Bolt (H) upwards into enlarged hole.

Secure with 5/8” Locking Nut (M).



Tighten the 5/8” x 4-1/2” Bolt (H) to 135 ft-lb. using

a torque wrench.

IMPORTANT: Upper flange of spherical bushing must

fit flush against the chassis rail bracket.

3.

CENTER FRONT AXLE HOUSING



The front axle housing must be in perfect lateral

alignment with vehicle chassis before Adjustable

Trackbar installation can be completed.



Before you center the axle housing, make sure the

vehicle is at normal ride height, on level ground,

with the suspension supporting the full vehicle

weight.



Determine if the axle housing is centered by mea-

suring the distance between the tire and chassis,

using the exact same points on each side of the

vehicle to ensure accuracy.

HINT: For example,

measure from the edge of a tire tread lug to the

outboard side of the chassis, then repeat the mea-

surement 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 dif-

ference in half to determine the amount of adjust-

ment required.

HINT: If the axle housing is not

centered, the chassis can be laterally shifted using

either of the following methods.

Ratchet Strap (preferred)

Â

Attach a heavy duty ratchet strap to the chas-

sis on one side of the vehicle, and to the axle

housing on the other side.

Â

Tighten the strap in small increments to pull

the chassis in alignment with the axle.

Â

Take measurements after each adjustment

until centered.
