Wow didnt know that, so they`re not the same at all, oil for the first and grease for the lower one… check.
Thanks!

Yeah, I only figured it out after pulling the tool head apart.
Hola, pudo resolver?
tengo el mismo ruido. saludos
My v3 plus makes that sound on the x axis moves at slower speeds, have you tried fixing it?
I have the same issue on my ender 3 v3 plus. The travel on the x axis is noisy and vibrates. The vibration is worse at slow speeds. I think the worst vibration was at 100 mm/s. I used the orca slicer vfa test to see what speeds and along what axis I was having the provlem. Its definitely.happening at slower speed along the x axis. Its definitely NOT a normal behavior. I dont know why anyone would say that. I’ll check my bearings and rods. It is difficult to determine the source.
No I haven’t. It’s really not that loud.
Ive the same problem and only has 1d and 17h of use.
Tengo el mismo problema y tiene 1f 17 h de uso.
I have a same issuse.
Mine is new and about 3-4 hours print😐
I tried to adjust belts but nothing happened.
Same sound like scratching metal and grinding + abnormal vibrations.
I think v3 plus is a buggy machine🥲

if you run the machine in silent mode the noise is really reduced but the printing times gets doubled.
I have same problem. Anyone here who find the solution or source of the noise?
I have the same issue with a brand new printer, couple of days old. I had also used grease on the top carbon sleave bearing, but after seeing @sleewok explanation, I cleaned off the grease and lubricated with machine oil.
The sound it creates actually doesn’t sound like scratching but wobbling/vibrating like on old matrix printers. So I took the printhead apart and noticed that both top and bottom bearings wiggle slightly in the casing of the printhead if you grab it on the sides and try rotating it.
One interesting thing @sleewok mentioned is that the top sleave is tensioned by springs (plural). I only have one spring in one of the top bearing holes. The other spring hole is filled with some plastic blocker. I would appreciate if anyone would be able to clarify if there are supposed to be two springs or just the one.
Other than that, I tried adding some latex around the top bearing within the casing to stop the wiggling, but it turned out the bottom bearing is actually the one which wiggles in the casing. The two set screws behind the hothead as @sleewok mentioned, do not seem to do anything than just hold the bottom bearing in place. Whatever I did with those, the bearing still had some wiggle room in the printhead casing.
I’d rather say the top or bottom bearing should have had springs going against the other rod rather than applying tension on the side. Perhaps that would have compensated the vibration on low speeds where it obviously achieves a resonant frequency.
I have the same problem on Ender 3 v3 Plus.

Any news? Solution?
I had the same issue. My way to fix it: you need to find two small screws in front side of printhead holding lower x axis bushing. Untighten them to free the bushing, then use your fingers to center it position inside printhead. Then tighten them back. Mine was not factory centered and after these steps problem never came back.

While waiting for a reply from Creality, might post this here as well.
Got new Ender V3 Plus few days ago and noticed the noise especially when its on a silent mode(ironically). Tried to check bearings and belts etc but everything seems normal and the prints come out fine. Moved the hotend by hand and the sound seems to be coming from belt rubbing somewhere. Took belts off and moving tool head is smooth and no sound or rubbing could be felt anymore. I’m guessing the belt guides between x and y axis are the culprit but those parts seem to be press fitted with bearings so I’m unsure how to fix this noise and preventing anything from breaking. Hopefully Creality will respond soon. Videos below for demonstration:
Hello @TeeMuumi …! 
Welcome to the Creality Forum…! 
I wonder if those belts are a little too tight or those 4 bearings might need a splat of sewing machine oil or something…
It also sounds like a belt is rubbing on something it shouldn’t.
I have the Plus and it’s a little hard to move the print head along the x axis but it’s not noisy…
The silent mode on these Ender-3 V3 / Plus is just slowing the speed down quite a bit so it’s quieter… 
Thanks Jim!
Tried to loosen the belts quite a bit and also tighten, no affect. Did according to creality tutorial(well it’s only couple screws). Also degreased and greased the rods which did not affect and like said, removing the belts completely made the sound go away(moving by hand of course). I’m guessing that the belt is either rubbing on those guides or the stepper motor is not aligned properly or something related.
Creality finally responded, however, only to ask video and receipt even though I already provided these so my hopes are not that high…

Hi, were you able to fix it? I have the same problem, tremendous noise on the X axis just like your video.
Hi.
Can u show this srew on photo or video?
No luck and no response from Creality yet either…
I’m wondering if it would be defected bushings after all but it’s hard to say. Definitely binding or not aligned and making the sound. Tried to degrease the rods and grease them but it did nothing. Also the upper rod does look like it’s not ok but it feels smooth to fingernail.
At this moment I feel like I’d like to return the printer completely and switch platforms but let’s wait a bit longer if Creality would respond.
Edit: Tried to check the two set screws that hold the bushings. Took them off and still made sound. Tightened back, still sound. However, the bushings didn’t feel that they moved at all when removed the set screws. Maybe they are misaligned or defected.
Edit2: Adjusting the Z-offset removed the waves so I removed that speculation from this post.
