I am in the process of replacing the subfloor, a few joists, sill plate and header board. With the help of this community I have either worked out a plan or completed most of the parts of this task. From what I have read, to replace the subfloor under my load bearing walls, I need to brace it, pull the footer and hammer it back in when the floor is in. What is the best way to brace this wall so I can get a full 4x8 sheet of plywood under it?
Edit I added a pic of the rafters in the attic, the row before the vent is sitting directly on that wall. Pic with the purple board is of the top of wall, there is another 2x4 hidden by ceiling. Obviously pic of bottom is just that.
