Lower ball joint replacement is done. Video in the second post. Scale of 1-10 about a 3.
My truck has had a 2" lift for years and these ball joints were originally replaced by Toyota under a TSB 16 or so years ago and 100K miles. They were leaking a bit of grease but overall in pretty good shape.
Next up, adjusting that Tundra/Bilstein 5100 suspension.
