Product Installation Instructions ING38955-061603
Part Number 38955/38975
CAUTION: Observe proper safety and repair procedures for installation of all chassis parts. Some chassis parts require specialized tools and
experience and therefore MUST be installed by a qualified technician otherwise an unsafe vehicle and/or personal injury could result. Wear safety
glasses and other protection.
WARNING: Before beginning, check for any damaged or loose suspension connections. Loose connections here indicate worn or broken parts which
MUST BE REPLACED. Failure to replace a damaged or worn spindle and/or link may cause the wheel to separate from the vehicle, possibly resulting in
serious personal injury.
NOTE: These parts are intended for use in vehicles with abnormal alignment and are designed to replace the non-adjustable factory equipment. These
parts are not designed for installation on vehicles with suspension and/or steering systems modified for racing, competition or any other non-standard
purpose.
Note for 38955: To minimize possible noise characteristics of polyurethane bushings, always lube with anti-seize, silicone, or naval grease 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 correct end link (match left and right hand threads, silver jam nut on left
hand thread end link [with first thread removed] and black jam nut on right hand thread end link [complete threads]). Assemble
SmartArm
TM by advancing both end links into the center adjustment tube equally until threads of the end links are no longer visible
(left hand end link into end of center tube with the indicator band near the end).
3. Raise the rear of vehicle and support body on jack stands in a safe manner. Remove rear tire and wheel assembly.
4. Remove the ABS wire bracket (if equipped) by carefully prying out the plastic tabs from the existing upper support arm bracket.
5. Remove the bolt from the inner end of the upper support arm at the body mount (save the bolt).
6. Remove the bolt from the outer end of the upper support arm at the spindle and remove the OE upper support arm. Take care to
not damage the threads of the bolt (you’ll need to re-use this part).
7. Install the bracket end of the new SmartArm
TM
onto the spindle using the existing OE bolt and torque the nut to 43 ft. lbs. (58 N.M.).
8. Install the other end of the new SmartArm
TM
onto the body using the original mounting bolt and torque to 43 ft. lbs. (58 N.M.).
9. Install the ABS bracket (if equipped) onto the new SmartArm
TM
by snapping the tabs into the ABS bracket.
10. Replace the tire and wheel assembly.
11. Adjust camber by loosening jam nuts and turning the center adjustment tube to the desired specifications. Make sure the dimples
in the threads of the end links remain INSIDE the center adjustment tube. Check for suspension clearance (see note below).
12. Place a wrench on the center adjusting tube and tighten the jam nuts. Torque to 80 ft. lbs (108 N.M.)
13. Verify camber readings and set rear toe to specifications. Road test and make modifications as necessary.
ALWAYS CHECK FOR SUSPENSION CLEARANCE
Modifying any suspension component may change other part clearances and cause binding or interferences. After installing any
Ingalls’ product, the suspension must be checked for binds or interference between all components, other arms and the chassis. Be
sure that all control arms, struts and steering ends move freely through the full movement of the suspension (springs may need to be
removed to fully check component travel). Installing any Ingalls’ product on a modified vehicle (lowered or raised) from the original
factory design requires a detailed check of all suspension components and their movements. Ingalls recommends that a trained
technician install all products.
