You might want to check the connection air cable too for the left side. I noticed on mine, one of them (blue cable) can't be tighten all the way. That caused my X not to stand straight, difference in height by quarter of an inch or something. Seems like you pretty much already checked everything, more stuff than me. I only checked two fuses, bags and compressor and that's about it. This might help you too:
