Do you have any fresh wheels to measure the bearing hole size prior to pressing a bearing in?

Since you have the problem I would reccomend that you contact Andymark so you can discuss the exact conditions that caused the failure. You are the team that knows the details and can answer questions as they are asked pertaining to the failure. That will be better and faster than another team searching for answers without having all the information in front of them.
