If the new jack is like my old one this IS the problem.
The nut on the bottom of the jack MAY be off also, but the primary issue is the set screw on the collar is loose.
By the way, the nut on the bottom of the jack is a left hand thread, (righty loosy, lefty tighty)
Taking the jack off, repairing and reinstalling is about a fifteen minute job.
There is a flat spot machined into the jack screw for the set screw to tighten against.
I went back with locktite thread locker. ( right or wrong)
