I did a search and found a similar topic on the old forum, but not the newer forum so.... Anyone had any experiences shelling out for replacing the AF-S motor on a lens such as the 17-35mm or any of the 70-200 or 80-200mm lenses? I am looking at fixing up a 24-70mm lens that was given to me for parts, but I see that the front and rear elements are fine as is the barrel and flanges. Clearly the motor is gone, but I can get this replaced here in Seoul by Nikon for $300-$400. However, I am wondering about any future problems that this lens sustained and if really a motor replacement would be enough. Again, this lens was simply given to me by a Korean friend of mine who works in the news agency at the Korean times...
I had Nikon repair a AF-S 300mm F4D and that cost around $400. The good news is that Nikon gives a 1 year warranty on any repairs, so if something does go wrong within that time at least you are covered.
