Install alignment tools (T69P-3000-A) into frame holes and tighten tools finger tight against upper arm inner shaft. Then, using a wrench, tighten an additional turn. Loosen bolts attaching upper arm inner shaft to frame. Firmly tap bolt heads to loosen lower assemblies. See Fig 1.
To obtain positive caster, tighten tool front hook nut or loosen rear hook nut. To decrease caster, tighten rear hook nut or loosen front hook nut. Check camber to see that it did not change. Tighten upper arm inner shaft attaching bolts to 120-140 ft. lbs.
