This sleeve will easily change Camber and/or Caster 1.00° for vehicles equipped with twin traction beam DANA 44 axles. Simply remove the tire, cotter pin and upper ball joint stud nut and break the taper free between the stud and sleeve. Using a sleeve puller, remove the existing sleeve and install a zero-degree sleeve (23109) to determine the required change, then install the correct degree sleeve. To split camber and caster adjustment, rotate sleeve 45°.
