I'm sure they are not worn out, the stock SRT pads have squealer clips that are annoying as hell. you will know when you hit them. they will squeal even when you are not on the brakes... even at that point i broke the clips off and got a couple more miles out of them in silence before i changed them out.
you might have to lube the backing plates on the pads better or do some hard stops to clear them out.
