Macbook Pro 13" Trackpad Problem

Ok so I just got a slightly used late 2011 macbook pro and the trackpad sounds different all over. If i press it on the left side it sounds like a normal click but if i click the bottom right corner it seems like it goes down too much and sometimes it makes a louder snapish sound. And the right side just barely clicks compared to the right side. Is there any way i can fix this cause its kinda annoying.

Nevermind. Researched it more after the whole trackpad started to make the loud noise. I kinda thought it had something stuck under the trackpad maybe so i blew into it while pressing the opposite side and it sounds normal now and both sides have the same amount of click to them.
