If it is a bad design, it won't work or fail in service.
If parts are misaligned, the system has to be adjusted to restore alignment.
Many pieces have to line up (within some fairly wide tolerances) in order to couple and uncouple a ball hitch system.
I put 2" ball couplers on my wheeled gensets, cement mixer and compressor to allow me to move them about with a compact tractor that has a 2" receiver welded to the front end loader bucket.
So I hitch and unhitch these things quite a bit. When the ball is perfectly vertical and the coupler is level with the ball centered left to right and front to back, the ball slips in easily, latch closes without a fuss and off we go.
When the ball is tipped (trying to get under the coupler) it won't go in or catches on the lock.
Trying to unhitch when there is a fore or aft load; forget it! Relieve the pressure and try again.
Now it is genuinely possible that there is a ding, dent, rough spot or misshapen part inside this particular sample that is causing poor operation.
The test I recommended above will clearly show it. If the ball goes into the socket smoothly and easily (no binding, grabbing or having to press it in). And it simply falls out when the latch is opened (and the latch operates smoothly). The coupler is not the problem.
That is a whole lot of IF's!
