Detroit DD15 chirping noise
There is coming chirping noise out of engine and when push accelerator that noise comes and truck cab/ engine shakes abit. Does not happening when idling only when pulling load. Ussually just before going uphill.
I thought it was bad fuel so changed fuel filter and didnt help.
The truck is factory emmission intact all stock cascadia with DD15 430,000miles. Any ideas where to start looking?
