Product Installation Instructions

ING38980-031411

Part Number 38980

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.

Before starting alignment, complete inspection checklist and determine the amount of change needed.

Ensure both jam nuts are threaded all the way against the correct end link (match silver jam nut to rubber bushing end link
and black jam nut to open, U-shaped end link). For ABS equipped vehicles, install the ABS mounting bracket (with free end
pointing away from jam nut, see figure) onto the U-shaped end link after the jam nut. Assemble SmartArm

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 groove near the end). See figure on back of this sheet.

Raise the rear of vehicle and support body on jack stands in a safe manner. Remove rear tire and wheel assembly.

Remove the ABS wire bracket (if equipped) by carefully prying out the plastic tabs from the existing upper support arm
bracket.

Remove the bolt from the inner end of the upper support arm at the chassis mount (save the bolt).

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).

Install the bushing end of the new SmartArm

into the chassis mounting bracket. Install one supplied washer between

bushing and chassis bracket towards the rear of the vehicle using the original mounting bolt. Do not tighten at this time.

Install the bracket end of the new SmartArm

onto the spindle using the existing OE bolt and provided new nut and

washer.

Install the ABS wire bracket (if equipped) onto the new SmartArm

by snapping the tab(s) into the ABS mounting bracket.

Use the outer two holes if the ABS wire has two tabs and the larger inner hole for a single tab.

10. Replace the tire and wheel assembly and lower vehicle to ground.
11. Torque the nut at the spindle to 43 ft. lbs. (58 N.M.) and torque the bushing end mounting bolt to 43 ft. lbs. (58 N.M.).
12. 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).

13. Orient the ABS bracket (if installed) to the same position as the OE bracket was located and place a wrench on the center

adjusting tube and tighten the jam nuts. Torque to 80 ft. lbs (108 N.M.)

14. 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.
