Yes... But you have to be fearless, wear a full face shield and leather gloves.... And most of all, brave enough to not cry if you slip and scratch the paint.... LOL, which I don't think you'll have an issue with...
Get a big Regular/flat head screwdriver. Get a ball peen hammer about a 4 to 6 ouncer, you will be holding the handle twards you with your shoulder and using the small side of the peen to pivot the spring...
Push the screwdriver stiffly into the spring just foreward of the end near the retaining nub's end. Place the spring end closest to you onto the swinging arm and shove the spring tighty into the jamb area.
With your left hand hold the screwdriver , placed over the peen end of the hammer, you may change hammer sizes to effect more or less pressure on the spring.
Push in with the spring and slide it over the retaining nub on the hinge by pivoting the screwdriver and the hammer at the same time...
Sometines this works sometimes it dont...
Nearly Every time it will scratch the jamb....
DO NOT TRY THIS WITHOUT PROPER FACE AND FINGER PROTECTION... The Spring will only bounce an inch or two outward but the screwdriver will shoot like a rocket untill it hit's something unless you have tiny chicken arms...
Somewhere there is a tool to install the spring but I have yet to find it... Maybe you should wait for a better way to do it... It's simple for me because I've done it well over a hundred times....
