I'm sure the original poster has figured this out by now, but I'll add my nickel's worth since I recently replaced the pins on my front doors. First of all, it's a PITA!
It takes two people, and one of them better be pretty strong to hold the door up when it tries to fall off the floor jack...
Getting the old pins out is a major challenge because the are hard to tap on, and they want to hit something as they come out. A fair amount of swearing is in order.
Tapping the new pins in is also a challenge because you cannot get a clear path for the hammer to strike the head of the pin. For the top ones, I used a socket extension and buggered the crap out of it pounding on it. For the bottom ones, it was tougher because the pounding has to be done from the bottom up, and there's no room to swing a hammer. I ended up putting a C clamp's solid end on the pin head and beating on the clamp. It was awkward, but it worked.
Oh, I forgot, each pin has a brass bushing (or two?) that has to be tapped into the hole where the pin head will be, and it's a sure bet you'll break the flange off the bushing when you tap on it.
Then there's the joy of trying to get the door detente spring back in. I used a vise to compress it while standing back in case of violent launching of said spring out of said vise. I used nylon tie wraps to hold the spring compressed (which didn't seem very safe) but they held until I got the springs put in the door hinge. With the door compressing the spring, I cut the tie wraps and the spring stayed in place.
There's a pretty good video on youtube of how to do this (maybe by the 1A Auto guy, if I remember correctly). The mechanic is far more experienced than I am, and he made it look very easy. It is not.
But, my door now closes nicely. Good luck to anyone trying this one.
