Nice vid, I like your style of explaining things.

Shame, as you could have fixed that without a new one if I had posted sooner .
There are 2 types of failures -
the cross connector becomes slightly dislodged (can be forced back in with screwdriver) and where the cross connector has moved completely and has no connection, or has broken, in which case you need to break off the moving part and can't reuse it.
In your case the 'lateral movement' you refer to is not wear, they are like that new.
it is an awkward attaempt at a security device . In your case if you had time to use an expoxy to bond in the contracted position (removing the movement and slack) it would have been ok.

Still easy to say that after right!
Good vid, keep them coming and good luck
