Installation
‰ 1. REMOVE ORIGINAL EQUIPMENT (OE)
FRONT TRACK BAR
 Remove front track bar and mounting hardware
per the factory service manual instructions for
your vehicle. Retain the original mounting hard-
ware as it is required for Adjustable Trackbar in-
stallation. HINT: It will be necessary to remove the
driver-side bumpstop to access the bolt on chassis
end. A flat head screwdriver is useful for removing
bumpstop from holder.
‰ 2. LUBRICATE BUSHINGS AT BOTH
ENDS OF TRACKBAR
 Locate the bag of parts containing the Polyure-
thane 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 on page 1.
‰ 3. MOUNT ADJUSTABLE TRACKBAR TO
CHASSIS BRACKET
 Mount Chassis End (B) of Adjustable Trackbar to
the chassis rail bracket and secure with the origi-
nal mounting hardware. Apply anti-seize lubricant
to bolt threads. HINT: When installed correctly, the
curve in Adjustable Trackbar should point toward
the front of vehicle.
 Tighten original mounting bolt on chassis rail
bracket to 75 ft-lb. using a torque wrench.
‰ 4. CENTER FRONT AXLE HOUSING
The front axle housing must be in perfect lateral align-
ment 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
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 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 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 adjustment until
centered.
Steering Wheel
 Have a partner turn the steering wheel in small in-
crements to shift the vehicle chassis side-to-side.
 After each adjustment, have your partner hold the
steering wheel steady while you take measure-
ments.
‰ 5. SET ADJUSTABLE TRACKBAR
LENGTH AND MOUNT TO AXLE
IMPORTANT: The length of the Adjustable
Trackbar must be set with the axle housing per-
fectly centered and the vehicle at normal ride
height.
