These popular sleeves are widely used to adjust caster and/or camber on many Ford and Mazda 2/4WD trucks. To install, simply loosen and remove upper ball joint pinch bolt. Remove top snap ring if one is present. Use 77880 or 88830 sleeve puller to remove the existing sleeve. To save time during alignment, use 23199 zero degree sleeve to determine initial readings, then install correct sleeve. Note: Sleeves adjust to a smaller degree on Ford 4WD light trucks.
