I wanted to let everyone know that I got it fixed! I tried to use the cable luber - it was pretty awkward, but managed to get a gracious dose of PB Blaster Silicone down the sleeve. I also had a good look at the whole mechanism, the spring was fine and nothing was broken or missing. Had a field day with that can of spray! Had a helper work the plunger while I was underneath with the PB. FINALLY heard that "click" of the release. Thanks to y'all I'm now much safer!
