Post subject:  X1'17 friction in upper arms pivots

In my X1 '17 I had a noticable friction while moving the upper arms up and down. To eliminate this friction and make them move smoothly on the pivots I grinded those pivots (part #373241) softly. I have used sandpaper 1200 and polished specially the 2 dots which left after a production process. After that I lubricated the pivots with very little of ball bearing oil and mounted them back into arm bushings. It seems to work much better now.
Do you guys have similar issues? How do you deal with that?
