Happijac failed while driving down the interstate!

4150s on the front. The Zed bracket was distorted by the now bent jack, that took all the weight as the other jack failed. There was no clicking or groaning. The inner part of the jack, like the previous failure,can now be pushed in and out freely. It is no longer held by the nut,I assume.
I'll certainly see if I can straighten the bent one out, but confidence is severely dented in the jack system right now.
