thanks for the reply. it seems to be single incident of one or two chirps perhaps a second long and so far only in reverse. once it's warmed up i dont notice it again in reverse. i thought perhaps a throwout bearing but your parking brake idea is interesting. i rarely use it though so would that still be a possibility?
