Certainly less glow than my scratchy sample (at €288 I'm not complaining)

I just picked up an m3 and Summarit 50 f1.5 on CL. Really clean and everything seems to work right. However the focus is a bit squeaky and feels like it drags abit, not smooth all the way through. I have tried taking it apart, i remove 3 screws from behind aperture ring, and 2 screws from focus ring. Aperture ring screws are left in place. I lock with small screwdriver into screw hole at focus ring. When i try to unscrew, the front part unscrews, the part with the front glass lens, and i can see the aperture blades still on the back end of the lens. I want to unscrew more down to the helicoid to clean and grease the focusing ring with helicoid grease. I am afraid to try to unscrew further while holding by the aperture ring. Any help would be appreciated please. I will post photos of what im doing later today, after i get home.
It is serial #Nr.1275494 M mount.
I am super excited about my firat leica and am now thinking about how i can afford a digital leica...
My latest one did the same thing: I screwed the front section back in, then used a rubber mat to grab the front section and aperture ring together to spread the force over a larger section than just the aperture ring. I had to press on the screw used to keep the block from rotating. It did come out.

Have you any recomendation what you think contributes to this issue? Lack of lubrication or something else? I will try again to separate them. Thank you!
