RANGER EDGE 4.0 4x4 5-speed.

A couple months back I had the lower ball joints replaced in my front end, and the mechanic noticed that my brakes were installed incorrectly on the left front wheel. He said the pads were wearing out unevenly so I would notice a little bit of squeeling at first.

I did notice the squeeling; every time I DIDNT have my foot on the break, and it was more of a clicking which sped up the faster I went and then would stop.

I HATE driving around with this annoying noise because I know it's really loud outside of my truck.

Then last night when I got home, I was putting air in my tires parked on a slight incline, where I noticed the truck making the click noise whenever I pushed anywhere on the truck (it acts up more after it rains it seems). It sounded like it was coming from behind the tire up where I couldnt see.

What could this be?? or am I just overreacting.

Thanks!!!
