Removing Hinge Pins

I've been searching for a few hours now and reading a lot of comments about changing hinge pins and bushings, but I haven't found anyone talking specifically about the newer trucks. I have a 2002 1500 HD and I need to chagne a back door.

 

In each hinge, there are 2 short pins, not one long one like the pre 99's. How do I get these out? I've seen the TSB that says they can't be changed, but I've also found a lot of places selling the short hinge pins and the door that I picked up from the scrap yard has half a hing attached to it. They had to remove it somehow.

 

Thanks in advance

I hope your not planning on putting on the junk door because in most cases the doors wont align up.The hinges have to be fitted to every vehicle because of the different assembly plants. The hinge & pin are a set and as far as i know its a dealer item only.

Thanks redvett. That's what I was planning to do. I was thinking that I would at least try to line them up and if they don't, then I'll have a body shop do it. I was hoping that with the advent of technology, that gm was using robots or a machine to put the hinges on and hoping that they would be in the same spot and work. I hadn't come across that bit of information yet though. Thanks. Maybe I'll just take it to the body shop as is and have them remove the old door and mount the new one. Just didn't want to pay for more work than I had to.

I am retired from GM Engineering and yes robots & fixtures are used but with 6 GMT800-900 plants its very hard to get all to be 100%. You may be lucky but with the stackup of tolerences its a crap shoot at best.

"The hinge & pin are a set and as far as i know its a dealer item only."

 

Any idea why there are so many hinge pin kits available for the truck? Or how people are changing the pins?

 

Thanks

I'm getting closer... I think

 

I found this site with most of the instructions for changing the pins.

Just missing one little piece of info in step 1. :)

"1. Remove door from body (Refer to appropriate service manual)"

 

Anyone have the appropriate service manual that can quote some text for me?

Thanks sagent.

 

Sooo, the door just lifts up off the hinge pins?!? Could it really be that simple?

 

I'll be giving this a try tomorrow. Hopefully I'm able to get it changed.

 

Thanks again.

You should be able to avoid thises steps. If its close to the OBS Pre'99 doors. You just need a jack(or anything to support the door) and a friend to hold it steady. A hammer and punch to remove/install the pins.

Thanks all for the replies. It really was just that simple to swap the door. Maybe that's why I couldn't find instructions online anywhere. Once I removed the bolt in the middle of the hinge, the door just lifts off of the pins. I had to give the bottom of the door side of the hinge a little love with a rubber mallet to pop it loose, but it was really quite easy.

 

The new door lined up reasonably well. It was about 1/8th - 3/16ths low, so I put a spacer under the hinge bushings and all was good.

 

I'm sure I'll be back with more questions as I get to know this truck. Thanks again,

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
