my truck is making this noise and does it the same way when i let off the clutch it chirps when i push the clutch in it goes away is this the throwout bearing??

 

plastic water bottle stuck under the pedal?

 

is that hard to replace? the truck has 112,000 miles on it i think i might just get a new clutch somthing better than the stock one

 

throw out bearing, my old bronco used to do that... pretty annoying.

You might as well put a new clutch in since it has to come out to replace the bearing.

 

ya i really noticed it the other day when i was at the bank with the windows down and in a enclosed area ya i figured i might as well but would it be a risk to keep driving it or could it really cause problems if i dont take care of it
