You can replace the bearings & seals without removing the drum.Remove the back panel(4 screws) & the top(2 screws).
Remove the belt & large drum pulley(1 bolt 13mm socket). Loosen the 3 bolts behind the pulley(13mm spanner) and then unbolt the spider(3 legged object) bolts are mounted around the side of the drum(13mm socket). The spider should rotate slightly and remove from the slots, you can totally remover the 3 bolts if it is a hard to remove. The Spider should then pull free from the drum. It actuall comes out through the back panel.
