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. HI N T: If difcult 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

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. HI N T: 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.
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 ange of spherical bushing must
t ush against the chassis rail bracket.

If the two measurements are equal, the axle is
centered. If the measurements vary, divide the difference in half to determine the amount of adjustment required. HI NT: 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.
