Be vary careful with a torch around any suspension parts, especially springs. You dont want to anneal the steel and weaken it.
I'm still reading your install, but the rear spring nut that fought you, let me guess it was on the exhaust side of things? They are always a PITA
I fought like heck with that bolt also, however I did not remove the shackles from the truck, just the springs.
And this is why I try to always follow up on my posts. A Fire Chief from a town in my county wants his Excursion to have the same spring swap I did on mine. Half the parts have arrived, and as I'm going through things in my head, remembering what I did, I couldn't remember if you tighten the springs with weight or without. Thankfully I remembered to put it into my original post! I'll have to post up a thread about it when I'm done. I'll be doing X/C code swap with an additional 2" of lift, and I'll be bullet proofing everything which wasn't already done....he already has studs and a coolant filter for example. Gonna be a "fun" couple of weeks.Re-installation was a bit of a pain because I had difficulty finding conclusive info on HOW to tighten everything down. When you tighten the shackle to the spring, you're locking it in place, so you could potentially create the wrong pre-load condition. Turns out, leave it all loose until the weight is on the tires and then tighten everything. Why couldn't someone have just said that outright in their tutorials? lol
