Jack must have been assembled with damage at the factory.

Update:Power Gear sent a "new" jack which was installed. When the QC inspector powered on the levelers the new jack promptly blew a seal. Now I am scheduled to return late in April to have another "new" jack installed. Lazydays has been great in the way they treat me. I just wish Power Gear would produce a fully functional product.
