GT380J Front and rear hub
Cut off all the spokes and remove ball bearings.
Cleaning and glass blasting.
Grinding. Did no grinding to the rear hub. You can still see the scratches from the spokes. Will not be that visble when new spokes are mounted.
On the front hub I grined quite a bit to get rid of the bigges scratches. Started with P250 paper and thereafter P1000.

Step 5, bearings
Mount new bearings, don’t forget the spacer in the middle before you mount the last bearing.
Be gentle when driving the bearings into position. Allow some slack to the spacer so each bearing can individually move freely.
