So in my process of bringing my wagon back to life, I have ran into some issues with putting my lift on, my bolts are all ceased in and I can't get them out, I can get nuts off but nothing with the bolt, they just spin in place, so I'm a week or so my buddies dad is gonna hit my bolts with a saline oxygen touch and cut them off, but before I do that I need new bolts, so could someone tell me the size of the bolts I need for the leaf springs on my wagon, my lift didn't come with new ones.
No, it's not critical. There's a metal sleeve that the bolts slide into inside the bushing. That's why yours are just spinning. The bolt is siezed to the sleeve. If you have a sawzall just cut the bolts with a blade between the hanger and the bushing.
For springs, grade 8 with nylock nuts. Tighten them just to the point that the bolt head and nut are both making contact with the shackle/hanger. The bolts are just acting as a pivot point for the springs/shackles. They aren't there to hold anything together, so they don't have to be torqued to any spec.
