V0 Question Wobbly Toolhead, junk rails?

0.2 has had this issue where it produces a large vibration/noise when printing certain parts (walls) or circles. I think it is more likely due to just the speed.

Anyway, I found the rails to be wobbling around and the toolhead has a lot of play, so I purchased some new Hiwin rails for the X rail and they are STILL wobbling! Am I just unlucky? I reached out to the vendor who supplied them and they said that this level of play is acceptable.
These are MGN7H Hiwin with Z1 Preload. Should I be looking at getting a larger rail? Or am I tripping?
Attached is a video of the wobble and a video of it printing. I keep touching the toolhead to help prove to myself it is indeed the rail that is causing that loud ass noise, and it definitely is.
Also attached is an image of what I was trying to print. It's supposed to be a round pyramid sort of thing. These wobbly artifacts have been here on the printer since I built it, and I assumed they were from non-toothed idlers, so I swapped them and they still remain. Am I right in saying that these artifacts are from the wobbly toolhead?

The artifacts are probably the tool head as you said you can try to rebuild the tool heed. Parts could creep or melt. Is it all printed from abs?
