Adjusting back door on a crew CAB

Without looking at it to see how the hinges are mounted, in general the bolts can all be loosened on one half of the hinge, then it can be slid up and down, and sideways. The bolts go into a steel plate inside the pillar. That plate is free to slide around, and the holes in the sheet metal are large enough to let the bolts move around.

Use a floor jack with a piece of wood and some soft carpet to hold the door up and to lift it small amounts as necessary. Start by loosening both hinges on the "B" pillar, then adjust the height so the body lines match. Trial and error will get you close. Snug the bolts just enough to hold the door at that height. This is just for the front edge of the door. The back will come later.

Now loosen just the upper or the lower hinge on the door so it can be pushed in or out to line up with the body that way. This will get you close.

Now you have to look if the door is tilted when viewed from the side of the truck. Once the height is set for the front of the door, you have to look if the rear edge has to go up or down. How that is adjusted depends on how the hinges are mounted to the "B" pillar. If you have to open the rear door to get to the bolts on the "B" pillar, you have to add or remove shims to push a hinge forward or backward. Which one you need to move depends on the size of the gap between the front edge and the rear edge of the front door.

If you see the bolt heads when you open the front door, all you have to do is loosen one hinge on the "B" pillar, then slide it forward or rearward. That will raise or lower the rear edge, and adjust the size of the gap to the front door. It takes a very tiny amount of movement to the hinge to make a big adjustment in the door's position. Use the floor jack, or some other blocking, to hold the door, loosen the hinge just enough, then lightly tap on the hinge to move it in small amounts. The rear should be in adjustment if the latch is centered on the striker and closes and opens without dragging on it. There are production tolerances though, so if all the body lines look good, but just the striker is off, that can also be loosened, then slid around.

Doors are easier to adjust when there is no weatherstrip on them. If you do not have that on yet, adjust the door first. If the weatherstrip is already on, it is usually more work to remove it, so just work with it installed.
