[QUOTE="rocketman122, post: 257785, member: 14443"] try mounting then remounting and see if that helps. also if you try turning the lens left and right when its mounted you will notice the mount has just the slightest play it. the little play might help with making the contacts work better. a small drop (the smallest drop possible) of contacts cleaner and use it on a lint free swab and rub both the camera mount contacts and your lens and see if that helps. your symptoms is the same mine went through. worked randomly then stopped completely. still a useable lens in manual focus. repair is between $300-450 try the AF from a close mark to a far mark and see if the squeak is more noticeable. Im fairly certain its dying. its the first version of the SWM and there were quite a lot of repairs done. when the AF is one then off, its pretty certain its going to be close to the end. the squeaking can be for a short or long time but its intermittent working is the problem. mine died when I was on shooting on the dance floor at a wedding. luckily I had a backup lens.
