Installation
1. REMOVE REAR TRACK BAR
Raise and support the vehicle chassis with jack
stands positioned in front of the rear lower suspension arm brackets.
Raise and support the rear axle housing with
a hydraulic jack to relieve any tension from the
mounting bolts.
Remove the rear track bar mounting hardware
from the axle and chassis brackets per the factory service manual instructions for your vehicle.
Retain original hardware.
Remove original track bar from vehicle.
Note: On RHD vehicles the pre-installed sticker is
upside down. A new one is provided to place over the
existing sticker.
Loosely install the original mounting hardware.
3. CENTER REAR AXLE HOUSING
Remove jack stands and lower vehicle to ground.
HI NT: 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
measuring 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
exact same points.
2. MOUNT ADJUSTABLE TRACKBAR TO
AXLE BRACKET
Apply anti-seize lubricant to bolt threads of original
track bar mounting hardware.
Insert Axle End (B) of the adjustable trackbar into
the axle bracket with the differential clearance
bend towards the rear

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 N T: 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.
Pushing Vehicle Body
Although this method will laterally shift the chassis
relative to axle housing, it does not enable the position to be easily stabilized while measurements are
taken.
 With the vehicle safely on the ground, have a
partner gently push on the vehicle body above the
rear wheels.
 Take measurements while your partner maintains
pressure on the vehicle body.
4. SET ADJUSTABLE TRACKBAR
LENGTH AND MOUNT TO CHASSIS
5. POST-INSTALLATION
Take measurements again to ensure axle housing
is perfectly centered and make any nal adjustments if necessary.
IMPORTANT: The rear axle housing must be in
perfect lateral alignment with vehicle chassis before you proceed with installation.
Once all adjustments are complete, fully tighten
the Jam Nut (C) to prevent Adjustable Trackbar
length from changing. HINT: It may be easier to
tighten Jam Nut with the Adjustable Trackbar removed from vehicle.
Using a torque wrench, tighten mounting hardware
at both ends of track bar to 125 ft-lbs.
Maintenance
Check torque specications regularly.
Regular cleaning with pressurized water is recommended to maximize reliability.
With the axle housing centered beneath the chas-
sis, adjust the length of Adjustable Trackbar by
rotating the Chassis End (A) until steel sleeve in
Rubber Bushing (D) aligns with the mounting holes
on the chassis bracket.
Apply anti-seize lubricant to original mounting bolt
threads and adjustment threads of trackbar. HI N T:
Bend in chassis (gold) end of trackbar must point
down to prevent interference from occurring when
suspension articulates. This is the same for RHD
and LHD vehicles.
