sorry I didn't get back on this sooner Juthro, been out of town for a while (may even have some pics worth showing)
mine has never given me the appearance of the motor going flaky. I've used the autofocus, therefore the motor, so little you could say there's no wear on it
mine is getting sticky. as in a very stuttery, unsmooth adjustment while turning the focus ring trying to find focus
so maybe your motor is struggling with the same kind of cruddy mess I assume is binding mine up. If you turn the autofocus off and adjust focus manually does the lens bind or resist adjustment?
maybe all that's needed is a good cleaning which, as near as I can tell, we can't do but the factory can
I haven't priced kit lenses more expensive than we're using now. seems to me the better ones have some special bells and whistles on them but have the same glass as ours just slightly larger, ergo one stop faster IF I remember right.
I've been working my ass off lately and have some mad money. Been thinking hard about which I want more - the D750 or some new glass. This is a good problem to have :)
