Weird trackpad click sound

[Shareen]

I have the late 2010 unibody MacBook and I just noticed that when I clikc at the trackpad it makes a weird sound. It's not like it was, it's louder and actually not normal. It's pretty noticeable. Should I be worried? The tapping and multitouch works great. Also when i click at the right lower corner, it almost makes no sound at all. This is quite weird and the worst thing is I don't have an Apple store in my country.

I know this thread is a year old but I had this problem too and just found a fix so I'm writing to the future viewers of this topic :

Try applying a good amount of pressure on the whole trackpad (not just where the click is weird) and release. I have also read about gently hitting it with your fist but I wouldn't risk hitting my MBP, so I suggest just pressing hard instead. Worked for me.
