This is my extremely low tech solution to the fact that my WO FLT132 focuser draw tube could tilt side-to-side. The design of the focuser appears to omit any sort of bearings except directly opposite the pinion. However there are two places where there are entirely cosmetic M4 screws plugging holes where you might attach a finder bracket.

I replaced those with nylon thumbscrews that I polished the tips of a bit (with very fine sandpaper). I tightened them just to the point where they make contact with the draw tube and confirmed they neither impede the motion of the focuser nor mar the tube.

They seem to provide just enough lateral support to eliminate the visible tilting I was observing. We’ll see how they work in the long term.
