OK, in that case you can change the bearings, bearing seal and tub seal on your machine.
Unplug the appliance, take the top and rear panels off.
Take the dispenser out.
Open the door and take the door seal retainer off.
Peel the door seal off the front panel.
Take the screws out of the door lock.
Take the plastic panel under the front panel off.
Take the screws holding the front panel out.
Take the screws in the dispenser out.
Take the knob(s) off.
Take the facia panel off. Be careful not to disconnect any wiring till you make a diagram and take photographs.
Take the screws holding the front panel on out.
Take the front panel off.
Take the dispenser unit out.
(you'll need to disconnect hoses etc to achieve this).
Take the bar across the front top off.
Take the spring retainers out.
Disconnect all hoses and wiring from the tub.
Cut any cable ties around the tub.
Once everything has been disconnected from the tub, lift it out of the appliance.
At some point in the disassembly you'll have to disconnect the motor and take it off.
Split the tub apart.
Take the pulley off the rear.
Take the inner drum out.
Once this is out you can remove the rear bearing, front bearing seal and front bearing.
Fit the new bearings and bearing seal.
Fit a new tub seal.
Reassemble the appliance.
Hope this helps
Let me know how it goes or if you need more help
