Installation

‰

1. REMOVE ORIGINAL EQUIPMENT (OE)

REAR TRACK BAR



Remove rear track bar and mounting hardware

per factory service manual instructions for your

vehicle. Retain original mounting hardware as it is

required for Adjustable Trackbar installation.

HINT: The original trackbar bushings may be

retained as spares for your Adjustable Trackbar if

replacement parts are ever needed. See Mainte-

nance section for details.

‰

2. LUBRICATE BUSHINGS AT BOTH ENDS

OF ADJUSTABLE TRACKBAR



Locate bag of parts containing Polyurethane

Bushings (E, G, H, & I) and Sleeves (D & F).



Liberally apply wheel bearing grease to surface of

bushings.



Assemble Polyurethane Bushings and Sleeves

at each end of trackbar as indicated in the parts

diagram to the left.

‰

3. MOUNT ADJUSTABLE TRACKBAR TO

CHASSIS BRACKET



Mount Chassis End (B) of Adjustable Trackbar

to chassis rail bracket and temporarily secure

with original mounting hardware. Apply anti-seize

lubricant to bolt threads.

HINT: When installed

correctly, the curve in Adjustable Trackbar should

point toward front of vehicle.

‰

4. CENTER REAR AXLE HOUSING

The rear 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 axle housing is centered by measur-

ing the distance between the tire and chassis,

using exact same points on each side of vehicle to

ensure accuracy.

HINT: For example, measure from the edge of a

tire tread lug to the outboard side of chassis, then

repeat the measurement on other side of vehicle

using exact same points.



If the two measurements are equal, the axle is

centered. If measurements vary, divide the differ-

ence in half to determine the amount of adjustment

required. HINT: If 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 chassis

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

on the other side.

Â

Slowly tighten the strap in small increments to pull

the chassis in alignment with the axle. Take mea-

surements after each adjustment until centered.

Pushing Vehicle Body
Although this method will laterally shift position of chassis

relative to axle housing, it does not enable the position to

be easily stabilized while measurements are taken.

Â

With the vehicle safely on the ground, have a

partner gently push on the vehicle body above the

rear wheels.

‰

5. SET ADJUSTABLE TRACKBAR LENGTH

AND MOUNT TO AXLE

IMPORTANT: Length of Adjustable Trackbar must be

set with axle housing perfectly centered and vehicle at

normal ride height.



With axle housing centered beneath the chassis,

adjust length of Adjustable Trackbar by rotating

Axle End (A) until the Bushing Sleeve (F) aligns

with mounting holes on axle bracket.
