OK, that is kind of what I expected.  But I'm sure they can be fixed.
Be careful as you disassemble further - unsurprisingly it can be easy to damage the parts.
I've still got a couple here in the pile of things to work on (for my HP 8657B).

I found this video and have already purchased some O rings from Amazon that will be delivered tomorrow. Assuming that the O rings are bad, would that cause the solenoid to fire only in the retract position? Or could the driver chips have failed as well?

MarshallPlexi:
Another good video for people like myself who are working through this.

Ah yes, I recall seeing one of his other videos on this topic



No idea if electronics are a common failure point on the newer models, but certainly possible.  The mechanical operation issues are quite a common issue with age.
From what I've seen other people reporting, yes they may stick in either state due to degraded o-rings.  My guess is that it might be due to a short actuation time not able to overcome extra friction.
Keep an eye out for any crap left behind clogging the holes or around the solenoid moving parts.

Oh, an hour long... I'll have to watch that another time.  I assume from a quick scrub through the video he has an electronics fault?
MarshallPlexi:
Have you ever had one of those days where you fixed something and have no idea what you did that fixed it? That was my day.
