All those "fixes" to quiet the noise with drops of oil strategically placed are only band-aids on a larger issue.

The issue would be addressed by a proper CLA. If you got a CLA and it didn't resolve it -- you got ripped off. They didn't do a full cleaning and didn't replace the worn parts. I had an AE-1P that squealed horribly for many years until I got it CLAed. When it came back it was quiet as a new model and it has remained so for many years and to this day.

I'm sorry to say I think you got swindled for the most part on your past CLA experiences.

H'mm so what about all the A model Canons that haven't been used much to wear anything out, but have the squeak................
