CHEVROLET (1965-70); Chevy II (1964-67): Caster
Turn the two nuts at front end of lower control arm strut as necessary. Shortening the strut rod increases caster. Lengthening the rod decreases caster. When adjustment is completed, tighten inside nut to 70-90 ft. lbs., and outside nut to 50-70 ft. lbs.
