Squeaking sound coming from 100-400 f4.5-5.6L mkII lens

Today I noticed a squeaking sound coming from my lens when I would focus from infinity back to its minimum focusing distance (3.5 feet).

The focus distance limiter was on (3 meters to infinity) I did not intentionally try to focus beyond the limiter, as I forgot it was switched. Afterwards, I noticed the squeak still occurred, but only when focusing back to the MFD, and it wasn't as loud.

Does this cause damage to the lens?

Has anyone else experienced this?

I just got in to photography and I love the artistic and technical aspect of it.
