I believe the end play is adjusted and center bolt is pressed in at the factory and not meant to be moved. Never have seen any kind of repair instructions on those antennas.

The units I've seen have very minimal end play of maybe 1/32 or less--just barely moves the armature up and down. In a previous lifetime, we used a thread & key locking compound on bolts, splines and shaft keys that once installed would almost be permanent to the point of stripping or breaking the screw head unless heated to break the bond. Perhaps one of the high strength Loctite products would work and keep it tight. Another option if there is enough metal might be to drill & tap the base and use a set screw or two against the end stud.
