Step 2: Remove the 14mm bolts at each end of the control
arms. In almost every case the rear control arms are in a bind
and require some messaging for removal. If the car is on a
drive-on type of lift, you will be able to roll the car back and
forth, greatly aiding in the removal of the bolts. Needless to
say, a crow bar may come in handy when installing the
components in your garage at home on jack stands.
Step 3: With the control arms out of the car, begin to assemble
the new control arms by threading the forgings into the steel
tubes, which have right hand threads and left hand threads
allowing for a wide range of length adjustment. To make sure
the length is the same as the OEM control arm, you can slide
the bolts into the OEM arms to serve as a guide for the length
adjustment. You may want to tighten the jam-nuts before
installation, but make sure to keep the forged ends aligned
properly. You can also tighten the jam nuts after installation, but clearance is tight for the wrenches.
Once you have the assembly complete, apply a generous amount of the supplied bushing lube to
eliminate any noise from the polyurethane where it pivots against the mounting brackets.
Step 4: One important feature of the Ingalls control arms is the
offset bushings at each end. The bushings eliminate the “splay”
or angle of the arms in relation to the chassis, which dramatically
improves the performance of the complete package. The large
bushing is used at the axle housing, while the smaller bushing is
used at the chassis. In addition, the offset on the bushings are
opposite at each end and critical to the installation procedure.
Installation is a snap, but you may encounter fitment issues due
to the binding of the whole axle assembly. Rolling the car back
and forth as in step 1, will aid in the installation of the arms and
bolts. If you are not on a drive-on lift, you may have to message the axle assembly with a pry-bar to
remove some of the bind in the rear suspension.
