I am not understanding to point of the tubes ERO229 that go inside the wheel bearings and over the axels ERO203
on the bogies as it seems to defeat the object of the bearings.
In my kit the tubes are spinning on the axels and there for the bearings are not doing there job as the wheels are rotating
on the tubes not the bearings.
Has anyone else had this problem ?
Or am I missing something obvious.

Thanks in advance
Regards
Derek
