Well, a lot of people have no idea what a door spring tool is or where to get them. Simply put a door spring tool compresses the firming spring in the door jam. Removal and reinstallation of this spring is necessary when servicing your hinge pins, bushings and hinges on any car door. Unfortunatly I've found that places like Autozone, Advance, Pepboys, Carquest, etc don't carry this tool. Fortunatly you can buy it online or do what I did, go to your local autobody shop the day their tool guy shows up and pay him direct...(Or if you happen to see a Snap-on truck, grab him). This is much easier than fighting with a prybar or trying to wire it down...
I picked up a Steck door spring tool. Steck part # 21900
http://www.steckmfg.com/21900.htm
Cost is $15.00
Simply push the tool in under the ends of the spring (not the outside of the spring) and tighten the 13mm nut on the side with a box wrench. The spring will simply compress and you pull the spring out. Install in reverse. Granted, pretty much everything described is simple, but this message is mostly for the inexperienced among us that we try to help.
Here is a pic in case you do manage to find it at a regular autoparts store..
