I know I’m a little late, but.... When you clean the bearings check closely for dark lines running the length of the needle bearings. If there are lines on the bearings it means that there was water intrusion at one point or another and that means rust. Immediately replace any bearings that have dark lines or are darker on one end than the other. Make sure you remove as much grease from the old hubs as you can if this is the case. As cheap as bearings are it’s not worth running on an “iffy” bearing.
