Installation

REMOVE ORIGINAL EQUIPMENT (OE)
REAR TRACK BAR

Remove rear track bar and mounting hardware
per the factory service manual instructions for
your vehicle. Retain the original mounting
hardware for the Chassis End 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 Maintenance section for details.

INSTALL TRACKBAR CONVERSION
BRACKET TO AXLE HOUSING
The factory trackbar bracket on the axle housing is too
narrow to accommodate the 2 Johnny Joint spherical
bushing. To mount the Axle End (A) of the Adjustable
Trackbar, the factory bracket will need to be converted to
accept the wider Adjustable Trackbar bushing.

Install JKS Conversion Bracket PN CE9121
(available separately) according to the
Installation Instructions provided with the part.
or

As an alternative to installing a conversion
bracket, the factory trackbar bracket may be
modified to accept the wider bushing. However,
modifications to the factory bracket require
cutting and welding, and should only be
performed by an experienced fabricator.

LUBRICATE BUSHINGS AT CHASSIS
END OF ADJUSTABLE TRACKBAR

Locate the bag of parts containing the
Polyurethane Bushings (E & G) and Sleeve (K).

Liberally apply wheel bearing grease to surface
of bushings.

Assemble Polyurethane Bushings and Sleeve in
Chassis End (B) of trackbar as indicated in the
parts diagram on page 1.

MOUNT ADJUSTABLE TRACKBAR TO
CHASSIS RAIL BRACKET

Mount Chassis End (B) of Adjustable Trackbar
to the chassis rail bracket and secure with the
original mounting hardware. Apply anti-seize
lubricant to bolt threads.


HINT: When installed correctly, the bend in Adjustable
Trackbar should point up.

Tighten the original mounting hardware to
50 ft-lb. using a torque wrench.


CENTER REAR AXLE HOUSING
The rear axle housing must be in perfect lateral
alignment with vehicle chassis before Adjustable
Trackbar installation can be completed.

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.

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
difference in half to determine the amount of
adjustment 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.

Slowly 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 position of
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.
SET ADJUSTABLE TRACKBAR
LENGTH AND MOUNT TO AXLE
IMPORTANT: The length of the Adjustable Trackbar
must be set with the axle housing perfectly centered
and the vehicle at normal ride height.

With the axle housing centered beneath the
chassis, adjust the length of Adjustable
Trackbar by rotating the Axle End (A) until the
Spherical Bushing (F) aligns with the mounting
holes on the axle bracket.

Apply anti-seize lubricant to 1/2 x 3-1/2
Greaseable Bolt (D) threads and adjustment
threads of trackbar.

Mount Axle End (A) of Adjustable Trackbar to
axle bracket and insert the 1/2 x 3-1/2
Greaseable Bolt (D) through mounting holes.
Secure with 1/2 Ovalok Nut (H).




Take measurements again to ensure axle
housing is perfectly centered and make any
final adjustments if necessary.

Once all adjustments are complete, fully tighten
the Jam Nut (C) to prevent Adjustable Trackbar
length from changing.

Tighten the 1/2 x 3-1/2 Greaseable Bolt (D) to
50 ft-lb. using a torque wrench.
HINT: It may be easier to tighten Jam Nut with the
Adjustable Trackbar removed from the vehicle.

LUBRICATE ADJUSTABLE TRACKBAR

Lubricate the 1/2 x 3-1/2 Greaseable Bolt (D)
at the axle end of Adjustable Trackbar using
common wheel bearing grease or equivalent.

Maintenance
Check torque specifications regularly.
The axle end of the Adjustable Trackbar features a
spherical polyurethane bushing which is both greaseable
and rebuildable. Lubricate the bushing via the
1/2 x 3-1/2 Greaseable Bolt (D) regularly as part of
vehicle maintenance schedule.
Regular cleaning with pressurized water is
recommended to maximize ease of operation and
reliability. Always lubricate afterwards to evacuate any
moisture.
The original equipment trackbar uses the same bushing
size on the chassis end as the JKS Adjustable Trackbar.
Upon removal of the original trackbar, the OE bushings
should be retained if in good condition. In the unlikely
event that the Adjustable Trackbar bushings wear out,
the OE trackbar bushings may be used as replacements.
