Wow Joe, you are a fountain of wisdom!The oilite bushings have probably dried out. The bushings are sintered bronze and are oil impregnated. if possible, remove them from their mounting. Put them in the oven at 350° for 30 minutes or so. Then put them in a pot with some lightweight motor oil (synthetic if you have some sitting around). put them on the stove and heat at 300° for about 15-20 minutes. The sintered bronze will soak up the oil and work as good as new.

Though I think i'll just pay the $44 and get a new one. Getting that bottom bushing back out will be a chore. Putting it back in it's place was enough for me.
How interesting though. Had I known this before putting that bottom bushing back in it's place, I would've tried this.
