Ratchet differential ?

[Shirlines]

this came up in our transmission exam, but it wasn't in the sylabus and none of the motor vehicle teachers had ever heard of it. we've tried looking on google but all we get are wishy washy answers on what it is. can anyone help us please, as we would like to know more about it.

if you arent a spammer try looking up detroit locker and see if that answers your question
