JKS Adjustable Track Bar Installation

Page 3

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.

Slowly tighten the strap in small increments to pull

the chassis in alignment with the axle. Take mea-

surements 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.

6. SET ADJUSTABLE TRACKBAR LENGTH

AND MOUNT TO AXLE

With the axle housing centered beneath the chas-

sis, adjust the length of Adjustable Trackbar by ro-

tating the Axle End (C) until the Spherical Ball (H)

aligns with the mounting holes on the axle bracket.

Apply anti-seize lubricant to original mounting bolt

threads and adjustment threads of trackbar.

Install Axle End (C) of Adjustable Trackbar to the

axle bracket by securing with the original mounting

hardware.

7. POST-INSTALLATION

Take measurements again to ensure axle housing

is perfectly centered and make any final adjust-

ments if necessary.

Once all adjustments are complete, fully tighten

the Jam Nut (B) to prevent Adjustable Trackbar

length from changing.

HINT: It may be easier

to tighten Jam Nut with the Adjustable Trackbar

removed from the vehicle.

Using a torque wrench, tighten mounting hardware

at both ends of track bar to 74 ft-lbs.

Maintenance

Re-torque fasteners after driving 150 miles. Continue to

check torque specifications as part of regular vehicle main-

tenance routine.
The Axle End (C) of the Adjustable Trackbar features a

spherical polyurethane bushing which is both greaseable

and rebuildable.

Lubrication

Lubricate the bushing via the Grease Zerk (J)

regularly as part of vehicle maintenance schedule.

Use common wheel bearing grease or equivalent.

Replacement Parts

Bushings are designed for maximum longevity and

it is extremely unlikely that any parts will wear out.

Just in case, all replacement parts are available

directly from JKS Manufacturing on our website at

www.jksmfg.com.

Cleaning

Regular cleaning with pressurized water is rec-

ommended to maximize ease of operation and

reliability. Always lubricate afterwards to evacuate

any moisture
