My non-AFS 300/4 has been squeaking, especially in cold weather when focusing. I've heard of the AFS motor in the current version developing this issue, but not so much the older, non-motor lens like I have.
Has anyone else experienced this? What did it turn out to be caused by? Where did you have it repaired? How involved was it, and much did it cost?
About 4-5 years ago, there was a post here about the 300 f/4 squeaking. I had never experienced this, but got mine out to check (hadn't used it in a while) and sure enough it squeaked, too. Seems like it occurs when the lens hasn't been exercised in a while (cold weather might do it too, but I spend winters in Florida, so have no direct experience). Anyway, I've used mine ever since, and aside from the occasional squeak, it's still working fine.

Many AFS lenses can suffer from squealing. Offhand I can think of 24-70's, 28-70's, 70-200's, and 300/f4's. I'd guess that the problem is endemic to all silent wave motors - although I honestly can't remember one of the DX lenses doing it (eg 18-200, 16-85, 18-105, etc). And there are one heck of a lot of those out there.

Yes, it appears fairly common for the NON afs version. Mine has always done it. Hasn't affected performance though, therefore I've never bothered to have it checked. Seems like a waste of money to bother with service.
I don't think my lens squeaks. But the non-AFS 300mm f4 lens focuses fairly slowly, so when focusing from near to far you can definitely hear the screw drive working. I can imagine with some samples the noise could approach a squeak. I doubt if it's a problem.
Mine is the AF-S 300mm f4 and it failed 3 months out of warranty. The sqeak, which is evidently quite common, is in my case the AF-S motor. The service department told me that this affected many 300mm f4 lenses AF-S and earlier and Ii needed a new AF-S motor (August 2011) at a cost of £325 or approx. $US 330. It's been fine ever since, but I think that will be the problem.

Thanks for the replies so far.
Just to remind everyone: we're talking about the non-AFS version.
My experience is that my lens, which I bought in 2003, started sqeaking intermittently in cold weather in 2012. It didn't make the noise before this. Focus seems a bit slower or less smooth possibly, too....but just a bit if at all.
