You tube is never wrong. But seriously, next time, try just putting the wrench in the BAS (bolt assembly screw)and put the bolt on a "carpeted" floor and step on the handle to break it loose. After that just snug is fine to put it back together.
On the put back together, I will use some thich non binding silicone #111 I think it is on the back threads and just a firm hand tighten down
