How to fix the stuck focus, WITHOUT fully disassemble the lens AF-s Nikkor 70-200mm 1:2.8 G ED
If the focus gets stuck about 1.5 meter in the AF-s NIKKOR 70-200mm 1:2.8 G ED, this is whats actually happen inside the lens, just behind the focus ring, and its "easy" to fix :-).
Its "easy" in a way to fix the stuck focus, WITHOUT fully disassemble the lens, just take off the rubber focus grip and pry off the tape with the thin brass plate.
Now you have via to long holes access to the little circuit board and the focus brush and you will probably see that the one end sticks out a little more to the edge than the other end, and this is why the focus gets stuck.
To fix the problem you will need some lighter fluid on a cotton bud to clean the tiny area and then apply a little 7386 Activator and then apply a tiny amount of the LOCTITE 330 Multibond glue, or you could just use a tiny drop of super glue.
The glue has to be add to the flat surface and up to the inner edge of the circuit board and closest to the inner tube, NOT!!! to the outer edge.
Now, you will then need to put a light pressure on the outer edge of the circuit board and press it as long inn as it can come, and keep pressing 10-20 min, until you will see the circuit board will not move anymore, when you release the pressure, maybe you will need to keep the pressure a little longe than you maybe expect.., and thats it!
Just check that the focus ring can move all the way from near end to infinity
Let the glue dry fully so there is no smell, BEFORE close the brass plate and the rubber focus ring, it can take 1-3 hours or so.
