Step 3 – Control Arms
A. Adjust front lower control arms’ length to an initial setting of 37-3/4” from bolt center to bolt center. Install
adjustable end of arm to control arm mount with supplied 9/16” hardware (zerk on bottom). If the fit is too tight
you may have to slightly grind the ends of the ball. Position the arms so the welded on brackets for the front upper
arms are on top and leaning toward each other– refer back to Photo 3. If necessary, final length can be adjusted
after putting vehicle back on ground and checking for axle position and clearance of track bar to differential etc.
B. Adjust front upper control arms’ length to an initial setting of 15-3/4” from bolt center to bolt center. Install front
upper arms’ rubber bushing end into the welded-on bracket of the lower arms with supplied hardware. The upper
arms will be used to adjust final caster and pinion angle after the lower arms are set at their final length.
C. Attach front lower control arms to axle with factory hardware, and attach upper arms to axle with supplied 10mm
hardware.
D. Reinstall any previously removed items and check all hardware to factory torque specs.
E. Align front end as soon as practical. Minimum factory caster and maximum factory toe-in seem to work best.
F. Recheck all bolts after 50 miles and again after every off road excursion.
