This sounds like it has been adjusted/serviced by someone and put back together incorrectly.
I purchased a 105mm f1.8 AIS lens which was a great performer but the front elements kept unscrewing. I managed to get a service manual and eventually worked out they had not put the lens back together correctly. Indeed after a couple of attempts I now have a perfectly performing 105mm f1.8 lens.

I think that wideangle zooms are more complex so I would agree that a trip to Erik Lund might be a good result.
