Installation
‰ 1. REMOVE FRONT TRACK BAR
 Raise and support the vehicle chassis with jack
stands positioned behind the front lower suspen-
sion arm brackets.
 Raise and support the front axle housing with
a hydraulic jack to relieve any tension from the
mounting bolts.
 Remove the front track bar mounting hardware
from the axle and chassis brackets per the fac-
tory service manual instructions for your vehicle.
Retain original hardware.
 Remove original track bar from vehicle.
‰ 2. MOUNT ADJUSTABLE TRACKBAR TO
CHASSIS BRACKET
 Apply anti-seize lubricant to bolt threads of original
track bar mounting hardware.
 Insert Chassis End (B) of Adjustable Trackbar into
the chassis bracket. This product is
 NOT compatible with frame-mounted track bar
drop brackets.
 Loosely install the original mounting hardware.
‰ 3. CENTER FRONT AXLE HOUSING
 Remove jack stands and lower vehicle to ground.
HINT: Vehicle must be 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 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 ad-
justment 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.
‰ 4. SET ADJUSTABLE TRACKBAR
LENGTH AND MOUNT TO AXLE
 With the axle housing centered beneath the chas-
sis, adjust the length of Adjustable Trackbar by
rotating the Axle End (A) until the steel sleeve in
the Rubber Bushing (D) aligns with the mounting
holes on the axle bracket.
 Apply anti-seize lubricant to original mounting bolt
threads and adjustment threads of trackbar.
 Mount Axle End (A) of Adjustable Trackbar to
the axle bracket by loosely installing the original
mounting hardware.
