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.

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)

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.

Tighten the strap in small increments to pull

the chassis in alignment with the axle.

Take measurements after each adjustment

until centered.
