Twin Tube Sleeve Assembly
This kit uses DJM's twin tube pivot sleeves. YOU MUST ASSEMBLE THESE SLEEVES CORRECTLY. DO NOT SKIP THIS STEP!!
-
The sleeves are already installed in the control arms. Cut the zip tie holding the nut and inner sleeve. Remove the inner sleeve and set both aside.
-
A small hole is drilled for grease to pass through to the inner sleeve. Although this is done at the factory, check that there is a 1/8" hole drilled through the zerk fitting hole into the bushing and outer sleeve.
Fig #1 — Verify 1/8" hole is drilled through zerk fitting hole into bushing and outer sleeve -
The drilling operation will leave a burr on the inside of the sleeve that must be removed. Use a rat tail file to completely remove all burrs from drilling and from the ends of the sleeves. Make sure you clean out any chips or dirt.
Fig #2 — Use a rat tail file to completely remove all burrs from drilling and sleeve ends -
Install grease fittings.
Fig #3 — Install grease fittings -
With the outer sleeves drilled and cleaned, check the inner sleeves. These sleeves should be about .050" longer than the outer sleeve. Assemble them before greasing to confirm length is slightly longer and they rotate smoothly. Apply some grease to the inner sleeve and insert into the control arm.
Fig #4 — Apply grease to inner sleeve and insert into control arm -
Install ball joint grease fitting.

Installation
-
Do not impact the pivot bolts. Clean bolts before installing. Replace factory nuts with the nylock nuts provided with the kit. Tighten to 30 lbs.
-
Before installing sway bar end links, loosen the 4 10mm bolts that hold the D-bushings to the frame. Install sway bar end links — you may need to raise the arm with a floor jack a little. DO NOT OVER TIGHTEN END LINKS!! 2 OR 3 THREADS PAST THE LOCK NUT IS ALL YOU NEED. Cycle the suspension to seat the sway bar and tighten D-bushings.
Correct — approximately 2-3 threads past the nylock nut
Incorrect — bolt is over-tightened -
Review all procedures and check that all parts are tight and installed correctly. Replace wheels and torque lug nuts. Check that the tires will turn both ways without making contact.
INSTALLER MUST CHECK THAT THERE IS ABSOLUTELY NO CLEARANCE PROBLEMS BETWEEN THE WHEELS AND TIRES, THE SPINDLE, THE CALIPER, THE CONTROL ARMS OR ANY OTHER COMPONENT BEFORE DRIVING VEHICLE.
Setting Toe and Alignment
To get the toe close, turn the tie rod ends in about 3 full turns. Turn your steering wheel until it is straight. By sighting down the tires and truck you can get the toe fairly close — adjustment is made with the tie rod ends. Loosen nuts at the rack and turn the tie rod ends until the tires are in a straight line from front to rear. Close is all you need; your alignment shop will correct this for you. Don't forget to tighten the nuts.
TAKE YOUR TRUCK TO A QUALIFIED ALIGNMENT SHOP FOR A PROFESSIONAL ALIGNMENT. ALIGN TO FACTORY SPECS.
Final Check
With the vehicle on the ground, measure the height of the front and record on your installation helper. Your measurements should be approximately 2-1/2" (CA25599L-2), 3-1/2" (CA2599L-4), and 4-1/2" (CA2599L-5) less than the before measurement.
REMEMBER: AFTER TEST DRIVING, INSPECT INSTALLATION AND DOUBLE CHECK ALL HARDWARE IS TIGHT.
