These heavy duty King Pin style joints replace the original plunging ball joint design on late model medium duty Dodge trucks and Sterling Bullets. Use part number 23850 to replace a worn OE ball joint. The 23852 will provide .5 degree and the 23854 will provide 1 degree of camber or caster change (camber only on 4WD models due to outboard axle seals) and will correct camber or cross-camber issues. They can also be used to add caster on RWD models for improved tracking. This greasable pin joint uses a bronze sleeve and hardened steel pin to ensure long service life.
