Abstract: A vehicle door assembly according to this invention has a hinge bracket for mounting on each of a door and body pillar of a vehicle. Each hinge bracket has a pair of spaced-apart legs wherein the pair of legs of one hinge bracket is received within and adjacent to the pair of spaced-apart legs of the other bracket when the hinge brackets are hingedly mated together. The hinge brackets have aligned holes formed through their respective pair of legs through which the hinge pins are received and secured to hingedly mate the two hinge brackets together. The improvement comprises that specifically machined, stainless steel hinge pins having, threaded tips or ends be installed in the, OEM hinge bracket holes and, with the use of a threaded locking nut, be pulled & secured into their respective places to hingedly mate these two hinge brackets together.
