Hey all,

I'm getting a high pitched squeak from the front of my motor that I'm suspecting may be a worn idler pulley. According to this diagram there are 2 idler pulleys. Does anyone know if they're both the same part#?

Not sure about 99, but on later models the upper one is a tension pulley assembly.
