Seals
Hello Steve
This is a common occurrence because of the build up of crud, you can try rubbing it back with your finger on the inside of the backplate, but personally I do find a small line of silicon sealant applied in the gap on the seal does help you don't have to smother it, once the seal is in then turn it round a few times to distribute the sealant and that should do it.

Right you can either change the bearings not a very difficult job if you have a good set of pullers.
or
Go to a motorcycle shop and buy a can of motorcycle chain grease make sure it has the spray tube, this is great stuff as it comes out like water so it penetrates the bearings and the leave it for about 10 minutes so the carrier evapourates you are then left with a nice coating of thick grease all over the bearings. It is best to remove the motor and sit it vertically to do the top one so it runs in easily.
As you spin the motor by hand you will hear the bearings get noisy at first and then they go quiet .
The back bearing requires you to remove the plastic cover so you can get access to the bearing and do the same.
This grease works on Hoover vacuum cleaner bearings aswell.
