Haven’t gotten the adjusters to release so I’ll try pull the drum

Don’t see where I can get anything in to pry between drum and backing plate

Plate wraps around drum pretty well

How bad of an idea is it to loosen nuts on axle shaft tube so they cover the end of the tube to protect it and put a plate to cover the tube to have something to push against and use a harmonic balancer puller to pull on the flange where the axle shaft bolts to?

What am I missing

If I mess up the drum are they available

Thanks
