On Vans the upper control arms are mounted on longitudinal rails and the lower control arms are mounted on a removable crossmember. Both control arms have replaceable bushings on the inner ends and ball joints on the outer ends. The upper control arms also control caster and camber adjustments through eccentric pivot bolts at the inner ends or through slots in the upper control arm mounting bracket.
