used bearings????

It is one thing to inspect and reuse the bearings that you removed from your own vehicle and another thing to use parts you have no direct knowledge of and trust them on your own car.
Did you buy used bearings of the internet to use on heavy trucks ? Do you think the owner of that truck would say to use them knowing that if they fail and cause damage to his truck that because they were second hand parts there would be no warranty for them ?
I think not.
Buying used bearings is not like buying used fenders.
Buyer beware.
