Door Hinges
Note: Light penetrating oils, such as WD40, should not be used because they wash out beneficial factory-installed grease, and they evaporate.
The door hinges on vehicles built before and after 8/1/2005 have different lubrication requirements. The hinges on vehicles built before 8/1/2005 should be lubricated, while those on vehicles built on or after 8/1/2005 should not be lubricated.
Caution: Do not lubricate the door hinges on vehicles built on or after 8/1/2005. Lubrication of these hinges could adversely affect the performance of the bushings.
To determine if the door hinges need to be lubricated, first identify the hinge by checking the top loop of the hinge bracket. See Fig..
Door Hinges on Vehicles Built on or After 8/1/2005

Do not lubricate this type of hinge. Lubrication could adversely affect the performance of the bushings. In addition, some lubricants may not be compatible with the hinge bushings.
Door Hinges on Vehicles Built Before 8/1/2005
On vehicles built before 8/1/2005, the door hinge center pin is flush with the top of the top loop of the hinge bracket. There is no dimple in the top or bottom loop of the hinge bracket. See Ref. B of Fig..
Lubricate this type of hinge every six months. Wipe old grease and dirt from the hinge, then force an approved grease into the hinge components; see Table.. Use an appropriate applicator that will not leave material behind. Wipe off any excess grease.
