I have experienced the exact same problem on my Creator. The problem was the timing pulley slipping on the motor shaft.
Tightening the set screw fixed the problem…for a while. Taking a closer look I realized the set screw was contacting the motor shaft at the very end so it would eventually vibrate itself loose. I had to flip the pulley around on the shaft so the set screw could do its job. Haven’t had a problem since.
I hope that solves your problem. Happy printing!

To bring it back to personal lubricants, talking to a colleague, he recommends, that we are talking about indoors, not needing heat or pressure resistance that Vaseline would be a perfect and cheap grease.
I will report back!!!
I’m not sure if you got it or not yet, but if not, and hopefully link’s are aloud here, I would check out www.3dprintboard.com 7 , they have a whole section for Flashforge, with a lot of people that know the in’s and out’s of the machine. I almost guarantee you can find your answer there if not yet
If it’s only occurring after some time has passed, it could well be that the motor is on it’s way out? I would hate to think so, but I can only suggest swapping the X and Y stepper motors around to see if the problem moves with it.

i think your Stepping drivers are over heating! i used to get this exact problem with Ramps Electronics, put a bit cooling fan over them and the problem went away! maybe if you can open up the area where the Electronics are and get a fan to blow air across and see if it makes a differance!
Good Luck
well… I ended up having this same problem… The stepper would make a grinding noise then the print would shift to the right. creating steps. I re-wired the x axis stepper and the problem was solved.
I am having a very similar problem.
In my case after about 10 minutes of printing, I will get a very brief grind from the stepper motor, which will cause a shift in the x-axis. A few minutes later the unit grinds terribly and the head travels randomly off the print grinding the whole time.
This appears to be an electronic issue, I have checked all set screws and oiled the rods. The x-axis will not jog making the same vibrating/grinding noise *until* I power cycle the machine. After a reset, the jog test on the motors is as smooth as can be.
I am experimenting with possible high temperature issues and am considering buying replacement cable, motor controller and Stepper motor.
By re-wired do you mean you replaced the wires between the stepper motor and controller? Or the wire running from the controller all the way back to the mainboard?
UPDATE: RESOLVED
My shifting issue and stepper motor grinding problems have been resolved. Since the company was paying for it I ordered a replacement stepper, controller and cable that runs between them. I then replaced the parts one at a time.
It was the cable. This thing is working better than new. Apparently that cable has been a problem for some time.
