If you suddenly experience a faulty or squeaky SWM after storing your lens for some time, it could be oxidation on the rubbing parts of the SWM.

Let me share a fix that does not require replacement.

A faulty compact SMW of a Nikon 16-35mm F4 that does not turn at all.



There's a C clip which can be removed to disassemble the motor.



Clean the rubbing parts with metal polish.
Take note: don't touch the metal parts with sweaty hands. Use glove


Reassemble and test

The procedure also worked in ring type SMW as well.

Here's a Nikon 300mm F4 AF-S with SWM problem.

I slipped a few toothpicks between the SWM stator and rotor to create a gap.
Cleaned the 2 rubbing parts with metal polish and it worked
