Squeal at end of print.

I have an M2 Dual which has been performing flawlessly, except for a loud squeal during a rapid vertical change, usually at the end of each print. I would say that it's a lubrication problem, but I can't figure out what I'm doing wrong.

3-in-1 oil wiped on to the vertical bars with a paper towel (both above and below the printing platform, with the platform run up and down immediately afterwards, and a touch of lithium grease on the vertical screw, both above and below.

Does anyone have any advice?

I had a similar problem; the know on the Z-axis rod was pinched by the wire housing on the extruder assembly.
