Cheers. I don't know if they are worn but since the trailig armas will be off it make sense to change them.
Experience tells us that ball bearings of the Murena will usually wear when the hub is extracted and reinserted as dirt tends to pass the seal. This is why the general recommedation is to replace the bearings when you replace the discs.
I mentioned this to a friend of mine who is a Honda mechanic - some Accords have the discs fitted under the hubs too, but he has never seen any problems with those bearings. The difference is probably not in the quality, but more in the construction of the bearing: The ball bearings have very low friction, but wear more easily than the roller bearings you will typically find on newer cars.
I agree with you that there's no point in refurbishing the trailing arms without replacing the bearings.
