I smells a rat! I suspect the original poster is posting a prank.
No Nikkor in my (rather vast) experience with Nikkor lenses has
ever shown the symptoms described above (including 3 180 AF's).
The 180mm f2.8 AF Nikkor is one lens that defines the high end
of AF lens construction and optical performance - one of the
few AF lenses that this diehard metal MF lens user would
seek out and own!
Hope this helps.
