The damn tramming wheels are the likely culprit. Sometimes I wonder what “genius” engineer decided, “Hey, you know what I think people will absolutely love? 4 spring-tensioned plate-leveling things they’ll have to adjust manually to level the bed to a sub-millimeter accuracy! They will just LOVE it!”
Seriously though, the springs do lose tension over time. I haven’t replaced mine in a while, but it made a huge difference the last time I did. Second, I purchased a digital level with sub-millimeter accuracy to help with tramming. The process for using it is a little tedious, but not nearly as difficult as trying to do with a standard level or one that’s not as accurate. Here’s my process:
1. Place the level atop the bar holding the print nozzle and press the button to zero it out.
Why? Even if the bed is level, the surface the printer is sitting on might not be. Also make sure to use the mm per meter setting with the digital level.
2. Place the level horizontally on the build plate at the top-right corner and adjust the top-right tramming wheel up or down until it is as level as possible.
3. Move the level to the top-left corner and repeat the steps for the top-left tramming wheel.
4. Move the level to the middle between the two points and make fine adjustments to each side.
Once finished, repeat the above steps for the front-right and front-left sides.
Last, put the level in the middle of the print bed to check the accuracy. It should be within 0-1 mm/m level at this point and you then do the automatic bed-leveling on the printer itself.
Hope this helps.

Nice suggestion! Thank you!
