I've recently bought a used Canon camera with some extra lenses, one of which in zoom lens ef-s 55-250mm, today i've noticed that when you go to the live view in starts to make some kind of a grinding noise, not very loud, noticable basically in a quiet environment or if you get close to it, but it's a bit annoying anyway. Also I am not sure if the sound was there last couple of days while I was using it.
If anyone knows if it's just a lens thing, or it's a problem that can or cannot be fixed, if it's serious or not - please let me know, would really appreciate it!
I've attached a recording of the sound, taken with a phone directly and very close to the lens. Noise Recording
There are a couple of clicks in the recording, that is me accidentally touching the lens with the phone. The sound itself is quiet constant.
You would want to put the headphones on to hear it properly.

I have no headphones, so I have not listened to it.
What is the full model number of the lens? I suspect that what you are hearing is probably the IS system in the lens. Try turning it off, and see if it goes away.

I think that is actually a full name of the model, there are no other specifications on the lens, eccept for aperture range (1:4-5.6) and that it has IS. I've tried the obvious options - turning thigs on and off, while the camera was on, while it was off, changing the lenses etc.
Also, I've notices that the sound dissappeares just for a bit right after I press the shutter and it makes the photo, when the mirror clicks, the sound dissappears, then back on track.

Did you turn OFF the IS, and leave it OFF?
What camera body are you using?
The model number should be written on the lens. If not, that is a potential problem.

I am using Canon EOS 70D, I did turn off the IS and left it off. I only found the serial number - [Removed serial number to protect personal information].

If your lens is bad, then it not worth the expense to repair it. But, I am not convinced that it is bad.
Is that what your lens looks like? Do you see the model number that appears at the front of the lens? This lens is the EF-S 55-250mm f/4-5.6 IS II lens. If you are uncertain, then I suggest that you contact Canon. Be aware, they will ask you what is the EXACT and FULL model number of the lens. There has been more than one version that has been released over the years.

This is what the EF-S 55-250mm f/4-5.6 IS STM, the latest version, looks like.
See the model number? I would expect your lens to be one of these two lenses. If not, and your lens turns out to be bad, then it is not worth getting it repaired.
There is a setting in the camera that enables and disables focus hunting, when the camera has lost focus. Disable it. Turn off the AF on the lens, and see if the lens can be manually focused. Make sure you are not too close to a subject, and that you have sufficient light. Going outside on a bright sunny day works best. Use “P” shooting mode, and note the exposure settings. What are they?
