Vivitar Aperture Issue

So I acquired a Vivitar 35-105mm 3.2-4 MACRO when I bought my ZX-7. The aperture ring on this lens does not "click" it a free flow ring (only lens i have like this) On it's own the aperture will stay wherever i move it to. Attach it to a body however and it has a mind of it's own. You can still adjust it with no resistance, but let go and the ring will slide back towards f16. It normally stops around f11 though. Assuming it has to do with the aperture linkage in the body.

This is not a fabulous lens I have to use(quite the opposite) but just found it strange and was looking for some info for future reference.

I think that particular lens has lost the little metal ball (about 0.5mm in diameter) that serves as the detent of the aperture ring.

Can be a DIY job to fix.
