Product Installation Instructions ING3860-011300
Part Number 3860/3862
Note: To minimize possible noise characteristics of polyurethane bushings,
always lube with anti-seize before installation.
1. Before starting alignment, complete inspection checklist and determine
the amount of change needed.
2. Ensure both jam nuts are threaded all the way against the center hex of
the adjustment bolt. Assemble SmartArm TM by advancing both tubular
pieces equally until threads of the adjustment bolt are no longer visible.
Be sure to match left and right hand threads of all parts.
3. Raise the rear of vehicle and support body on jack stands. Remove rear
tire and wheel assembly.
4. Remove the two bolts from the inner end of the upper support arm at
the body mounting bracket.
5. Remove the nut from the ball joint at the upper support arm. Using a ball
joint separator or similar method, separate the ball joint taper and remove
the support arm. Take care to not damage threads of ball joint.
6. Remove the clip ring (if equipped) and rubber boot from the ball joint.
Inspect ball joint taper for signs of wear and replace if necessary.
7. Using a press or suitable method, press out the ball joint from the OE
support arm. Use care when removing the ball joint so threads are not
damaged and grease is not contaminated.
8. Using a press or suitable method, press the ball joint into the SmartArm TM
from the top with the opening in the SmartArm TM angled slightly downwards.
WARNING: IMPROPER BALL JOINT INSTALLATION WILL RESULT IN DAMAGE OR BREAKAGE
OF THE NEW SmartArm TM AND POSSIBLE DAMAGE TO THE VEHICLE.
9. Reinstall the clip ring and boot on the ball joint.
10. Install the new SmartArm
TM onto the body using the two original mounting bolts and torque to 28 ft. lbs. (38 N.M.).
11. Install the ball joint stud into the spindle, torque ball joint nut to 29-35 ft. lbs. (39-47 N.M.).
12. Replace the tire and wheel assembly.
13. Adjust camber by loosening jam nuts and turning the adjusting bolt to the desired specifications. DO NOT exceed more than 3/4”
(19mm) of exposed threads on either side of bolt.
14. Place a wrench or vice grips on the flat of the tube next to ball joint. While using the wrench to keep the ball joint body
perpendicular to the ball joint stud, tighten the jam nuts on the adjusting bolt.
15. Finish tightening the jam nuts by holding the adjusting bolt and verify that the ball joint is still aligned properly at the spindle.
Set rear toe to specifications.
