Removing 3rd Door "03" S-10 Zr2 Pickup

49100

Hi All
Bought an awesome "03" S-10 Zr2 for my Son, Not bad for a 16 year old with a Learners Permit, Right.
Needs a little TLC, Lower 3rd Door rotted thru (New England Truck), Bought a Replacement Skin Panel for him and I to do Body Work - he's a good learner and would be nice to Remove the entire Door for this job.
Looks to be some kind of Swedged Hinge Pin Retainers at the top of the Hinge Pins.
Any Info or Pictures would be greatly appreciated.
Thanks

Hi All
Lot's of "lookers" but no one willing to Jump In :)

So I decided to figure out how this could be done.

At first I thought the Pins were held in with those "Hat" type of Retainers you would see on the end of a Wagon Axle - Pushes on and held in place with Friction tabs - Not !

After I cleaned the Tops, I saw the Retaining ring, I believe it is thin Stainless and they are just pressed down over the top of the pin that Sticks out, I used a thin chisel to pry up and remove.

What really holds the Pin in is the Straight Knurled section, it's a few thousands larger than the Hole in the Hinge Fitting and really bites in, Soaked with PB Blaster- nothing moved.

Then I realized I also needed to support the Fitting from the Bottom while Driving the Pin Down so I came up with using a 1/2" drive 12pt deep socket on several extensions and used my Floor Jack to raise up just until I stated to lift the Truck, One of the Pins is Behind the top aft corner where the Body is formed over it - I used a Big Heavy Pry/ Pinch bar we use in the Yard for Rocks, Placed that on Top of the Pin and used my Biggest Hammer and gave a few hits Downward and the Pin moved about 1/8", once you get it started, then you can use a Drift pin to continue moving it Down thru the Door Hinge Fitting.

I also used several small screws in different lengths to keep moving the pin Down thru the Fitting as you cannot get a Straight shot down for this Pin. I put a small open end wrench in and hit that Downward to remove the Pin. Also put some Duct Tape on the corner of the Door Skin so I would not hurt the Paint finish.

There are 2 Pins for each Hinge Assy. The Inboard Pin is the Pivot Pin, the Outboard Pin is what the Door/ Hinge Assembly Rotates kind of Inward as it moves backwards almost Pivoting within itself and is the Door "Open" Catch.

I thought I could use a big "C" Clamp to Press out these Pins but I have a big 8" Clamp which would give allot of power, it's too long and Inside the Door Jam, you can't Turn the end.

So I came up with using the socket on a bunch of extensions and the Jack to "stiffen" up the Hinge when you hit "Down" on the Pin.

I put the Pins in my 12v Drill and sanded the Knurled section off so I could put them back in for my Son to use and Close the Door as this will be an ongoing project for like a week until we can Remove the Door, Remove and Replace the New Lower Door Panel and then take the Door and have it Painted.

I ordered New Pins at my Local Chevrolet Dealer, like $2.00 each, I had to order 5 - No Problem to get the 4.

Sorry to be so "long Keyed" with this description but wanted to make sure anyone wanting to do this has all the info. Pictures are too big, contact me and I can Email them.
