Got my 400mm f2.8 AFS ED ii back from FixationUK.  They said it had a squeaky SWM but that happens when the lens is not used all the time!  Bad Nikon design or sourcing of bits.  However if you know about these motors it is not eminent failure but usually complaint of lack of use!
I am not giving them a superb lens of value £4k for £1200.

I had a squeaky Nikon lens and was told that there was an aluminium strip 'in there' that can oxidise and needed regular use to wear it off...if possible. It was suggested I put it in manual and focus it rapidly back and forth for a new days - 'sometimes they free themselves up”.

So I did this and I have to say it did quieten it down a bit but there was always a faint squeak. I eventually sold the lens on eBay declaring the squeak and it made 3/4 the price 'perfect' examples were making.
  
I suspect the resale price of these heavier long primes will have been influenced by the new FP lenses in some quarters. It will be even worse if/when Nikon bring out 400mm and 600mm version.  With Sony bringing out lightweight telephoto lenses it may spread up that release...once the world heals.
