Alright, so we went in-depth to explain to you what a drive socket is in the case you see one when shopping around. However, this leads to another important question of whether or not you will need to replace them. It will depend on how much you use it but yes, if a drive socket is integrated then it will need to be replaced eventually. About the only thing you can do is inspect them regularly. As it is a wear item, you should check the outside of them for gouges, nicks, cracks, and any other damage.
Do not hesitate because as soon as you notice damage developing, replace the drive socket. By the same token, if the inner gear teeth on the drive socket are worn then you should replace it immediately.
