have to slam door

[chris1htx]

hello all, for the past two years i have been having to slam the doors on my 84. the truck was painted and had new seals installed, i figured after a while the seals would be broken in but still nothing. it is not my daily driver so it never really bothered me but i'm wanting to figure out the problem now. the truck has been set out in the sun so the seals can "form" but still nothing. i figure maybe the doors weren't aligned correctly. i'm nervous to try to realign the doors (never done it before), especially having to rematch the body lines.

does anybody have any idea of what is maybe making the doors hard to close? or is the door alignment probably the main cause?

of course rolling down the window helps significantly with the door closure. any help will be appreciated.

You need bushings on your striker pins. This one here DOES NOT have the bushing. There's a thread on this, I'll find it and then post it here.

Your welcome!! When you do the repair, let us know if it helps.

And don't forget, once you add new Strikers, they do have to be adjusted. Plus, you might want to replace hinge pins as well if there is up/down play in your doors. Both are a very worthwhile and somewhat easy upgrade.

go to home depot and buy a couple feet of "pex" plastic tubing, it is the perfect size to replace the ones on your existing strikers...I am lazy, so i just cut the correct length I need and split it and slide it over the striker....

Pex pipe! Used that also. works like a champ! but you'll have to by a 6 foot stick for the 3/4 inch you need...

These doors never closed well, because there is not a lot of "mass" to them to help generate momentum, and because they are pushing a lot of air into a small cavity (the regular cab volume) and it can't vent quickly enough.

If rolling the window down slightly helps significantly then I predict it is an "air" problem rather than a mechanical or adjustment issue with the hinges/pins/latches. You can remove the PRVs ("pressure relief valves") in the bottom of the doors and that may help, but you may notice a bit more road noise and dust intrusion.

For over forty years now (our first squarebody was a '75) I just always planned on pushing the door home, rather than swinging it and expecting it to latch.

Keith - I think you would know this - I had my doors apart this last weekend. I noticed they had a square piece of heavy paper duct taped over the larger opening in the door inner panel - is that just for dust control? Mine both fell off right away and I didn't replace them.

Yes - dust and water.

I will say I was one of those guys that was skeptical about the plastic bushing making a difference on shutting door. So I went cheap route and bought a 6 foot piece of 1/2 pex for 3.00 at Lowes. I also took the lazy way and just cut one side of pex and put on striker. WOW what a difference, I cant believe it. I have a 79 truck and a 82 Van and they have different diameters on striker neck but did not matter they both shut like a dream, no more slamming the doors. One day I might take striker off and slide a piece of pex over it but for now, a slit on 1 side of pex and doors work great. Well worth time and effort no matter which way you go, pex or OEM bushing.

I have new, rubber, new bushings, and hinge pins, on my '85 and my doors still need a little persuasion to close them. Kieth is right, it is the nature of the design.But when my window is cracked, it is very easy. You cant fight Newtons laws....

[Jstock85]

I agree with Tucson....better yet get a buddy to help. I did this solo and it was not easy!

[DieselSJ]

I had some PEX left over from a plumbing project. Took less than 10 minutes to do all 4 doors. Best 10 minute, <1$ project ever.

[WyattTX]

Does someone have a picture of a striker with PEX on it? Thanks.

[HunterRotten]

I don't have a picture because my cab and doors are at the body shop and have been for awhile, but I can vouch that the pex does work and made my doors close tight. They felt solid.

The "HELP" product is shown, but the PEX tube would be where the grey part is on the striker.

Here's my after & before pic. I replaced the whole striker with a new one, already has the pen on it. My strikers were pretty tore up.

[WyattTX]

Thanks, I understand now.

[chris1htx]

A little update for you guys, I ended up buying new strickers. The old ones were pretty bad looking so I'd thought I'd just replace them, just $7 a piece. Man did those did those new bushings help, the doors close with ease now. Except for the passenger, it still struggles a bit. I was looking inside the the door jam and there is something that sticks out, im guessing it helps push the door open? Can It be removed?

That's the plunger switch that turns the dome light off and on.

Could it be pushed in so it doesn't stick out as much?

You should have one on both sides. You might just want to replace those too. They are supposed to be out when your door is open. And then when you close the door, the door pushes it in. Like Keith said, these are the switches that turn your dome & courtesy lights on, when you open your door.
