Loose Element

I have encountered something today I never have before, and I think it is a loose lens element.

Problem: The image through the viewfinder will slightly shift
laterally/horizontally.

Body: Olympus E-520
Lens: 14-42mm f3.5-5.6

When:
1) during AF (The lens' hunting sounds and actions match perfectly with the movement.)
2) only when focused on subjects within approx. 2ft.
3) on initial attempt to focus on subject or on the immediate second follow-up attempt to finalize focus
4) happens randomly

How:
1) laterally/horizontally (maybe with an occasional slight raise up and to the left)
2) shift movement distance = 1/2 to 3/4 the diameter of a focus confirmation dot
3) sometimes only in one direction
4) sometimes in one direction then back again, or then again a third time in the first direction (back & forth)

Have I got a lens going bad?
