Product Installation Instructions ING38150-100902
Part Number 38150/38170/38180
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 3815: 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 nut and bolt attaching the later links to the spindle. For Chrysler vehicles right side only – support the fuel tank and
remove the four cross member to frame bolts (Note: Lower the cross member just far enough to enable the lateral link bolts to
clear the fuel tank).
5. Remove the nut and bolt attaching the lateral links to the rear cross member.
6. Install the new SmartArm
TM on the front of the cross member with the head of the bolt toward the front of the vehicle and install the
nut. For the 38180, the wider spacer end attaches to the cross member end (inboard body mount).
7. Re-install the rear factory adjustable link on the cross member and re-install the cross member. For Nissan Sentra vehicles,
replace the rear factory non-adjustable link with another SmartArm TM in the same manner as the front SmartArm TM .
8. Attach both links to the spindle with the head of the bolt to the front of the vehicle and install the nut. Torque the later link nuts to
105 ft-lbs (140 Nm).
9. Replace the tire and wheel assembly.
10. Adjust camber by loosening jam nuts and turning the center adjustment tube on the SmartArm
TM and turning the center bolt on the
factory link (or other SmartArm TM for Nissan vehicles) equal amounts to the desired specifications. Make sure the dimples in the
threads of the end links remain INSIDE the center adjustment tube and enough threads remain inside the factory links. Check for
suspension clearance (see note below).
11. Adjust toe-in by lengthening the rear link and shortening the front link. Adjust toe-out by lengthening the front link and shortening
the rear link. Tighten all jam nuts to 80 ft-lbs (108 Nm) after adjustments are complete.
12. Verify camber and toe readings. 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.
