Thanks for the info - I ordered them through RMBEARINGS and they should arrive on Friday.

Great.
Be mindful of axle nut torque values. Too tight or too loose can waste a bearing very quickly. A spec sheet with the bearing, or online, can show the correct torque value.
Banging it on with an impact wrench is not correct.

5.3.4 ALKO EURO Axles are equipped with maintanance free compact bearings

If necessary, adjust the axial play of the wheel bearing
- Remove the decoration and the wheel-hub cap.
- Remove the split-pin from the castellated wheel nut.
- Tighten the nut while spinning the wheel until a resistance is felt. If possible use a torque wrench
(50 Nm).
- Turn the castellated nut 1/12 of a turn (30°, see diagram 1) then turn back to the next pin
alignment position.
Axial play to 0.05 mm is acceptable.

Overtightening will cause bearing damage
- Check grease for quantity and condition, top-off or renew, if necessary
- Grease type for wheel bearings: Multi-purpose grease DIN 51825 KTA3K
- Replace wheel hub caps
