I think you will find that it's not too bad of a job as long as you can get the bolts out of the spring eyes. If they are seized, I usually use a sawsall on the bolt (inside the shackle against the spacer/eye) and be careful not to cut the shackles. Since the spring is being replaced anyway, it doesn't matter if the spacer is cut, etc. Sometimes I had poor luck getting the U bolts loose, and used the same method and just cut one side of each bolt. Be very careful and make sure your rig is suspended safely, and be aware that cutting the u bolt will allow the spring to become uncompressed instantly. As mentioned, new u bolts are a must, and I had no issues getting the spring to line up as it will move easily on the shackle to align the bracket bolt. I used anti seize on the new eye bolts. Not too bad of a job, thought it would be worse as bigger heavier parts are a bear sometimes. Hope this helps.
