Easily replace motorcycle fork seal quickly without taking forks completely apart

When changing a leaky fork seal, most videos show the entire fork being dismantled . They take out the lower hex screw and use the stanchion to hammer the seal out.
The lower hex screw is very difficult to remove and there is then an increased chance of fork oil leakage at this point.
