The pivot bolt had worn completely throught the bushing, and then wore a channel into the spring eye itself.
Considering how much weight is borne by each spring eye (appx. 375 lbs. max. : 3000 lb GVW ÷ 8), and that JB Weld has 3960 lbs tensile strength, I figured it should work. Time will tell, but it's got to be better than no repair at all.
