If they bearings are removed properly and they are in good cond.,I would reuse them.
If the bearings are replaced,I bet they could be bought for less at a bearing supply house.
I would not buy any bearings made in CHINA.

BTW,who makes the HD bearings and where are they made?

 

Locally we have a machine shop that specializes in bearings. My father in law took his old bearings in and they got the number off of them. Same bearings for six bucks I believe.
