Chevrolet Astro: rear knock the pin out, but I

This answer was rated:

How do you replace a rear door on a Chevrolet Astro Van? They are welded on, not bolted. At the used parts yard, where I bought the replacement door, they said you knock the pin out, but I''ve tried, and I don''t think that''s it. They never knock the pin out, they cut it off of once side of the hinge right at the pin, so you only get one half of the hinge (attached to the door), the pin, and a stub.


Can you tell us what year your Astro is?

Hi again.

Here are the instructions, which is pretty much what the guys at the yard said.


See Figures 1 and 2

Fig. 1: Rear door hinges


Fig. 2: Rear door check assembly


  1. Disconnect the negative battery cable.

  2. Remove the door trim panel on the right door only.

  3. Disconnect the wiring harness from the license plate lamp and power door lock, if so equipped. Remove the harness from the door.

  4. Disconnect the check strap from the door frame.

  5. Drive out the hinge pins while an assistant holds the door in place.

  6. Remove the door from the vehicle.

To install:

  1. With an assistant, install the door onto the vehicle.

  2. Drive the hinge pins through both hinge halves.

  3. Connect the wiring harness, install the trim panel and connect the negative battery cable.

About all I could recommend is that you try to get some penetrating spray in there to loosen up the pin, or perhaps apply a little heat to make the outside expand a little. These can be a real pain once they have been on there for some time (like 20 years or more).

I hope this helps.

Take Care & Good Luck, Greg A.
