I've been browsing lenses on e-bay and I see several Nikkor 28-70mm 2.8 lenses where cautions to "READ" the descriptions say they squeak. One mentioned the squeak is why they are "selling cheap".

What's with the squeak? Is it something to be concerned about? Inconsequential?

I would buy only lenses that are listed as Very Good to Mint anyway and wouldn't buy a squeaky lens; but I would like to learn about this squeak thing.

Here's a demo of 28-70 squeaking for anyone interested:

As to why these ring type SWM fail, I quote Roger Cicala:

"As to how ring USMs fail, they are a stack of rings, torqued to a certain tension and then glued in that position. The stack can loosen from long term use or from shock. Sometimes we can replace and reglue and get more life out of the motor, but generally the entire motor has to be replaced. Once they start squealing, the stack is loosening and failure is going to occur, although it may be quite a while."

I replaced the motor in my 17-35 when it stopped working and it was expensive; well over $300. At this point I think I would be looking at used 24-70 2.8 AF-S lens. They may not be as nice as far as construction goes but you get an extra 4 mm of reach and they have a newer generation motor which, I believe, can still be replaced if it goes bad.

I had the SW motor replaced on my 28-70 2.8 last year by Nikon Canada. It cost $358 (Canadian dollars) so apparently the repair parts are still available. Works perfectly now. It never squeaked, the AF just quit working one day.
