I did a full frame replacement, unfortunately I did not do a video this time as my time didnt allow it as I work in a different city from where my house is. But if you have questions feel free to ask since its still all fresh (or scarred) in my head
Its not all that difficult to do, just alot of parts to keep track when putting it back together. The only part you may have trouble with if your doing it alone is getting the tub off and back on.
Again feel free to ask...
Removing the TUB, I was lucky to have a Cherry picker to lift the tub from the center where the seat bolts go but it was still back heavy where I was lucky enough to have a small backhoe to help with the off balance and move it.
