I found the problem! There's a part that screws the cane together (I don't know how to describe it) and it was loose. I tightened it and not much noise.

Ladies, I miss my shoes too!!! It took me about 8 years to finally get rid of my last pair of heels, wedges included. It truly was a sad day for me. My DD27 had to keep assuring me that flats can be cute and feminine. I still am not used to the idea of wearing flats when going out to dinner or gatherings. I stress about it every time. It's been 2 years since I gave away my beautiful maroon pumps, heeled boots, wedged sandals, etc. I'm still in mourning.
