I have a 1999 ford expedition 5.4 trition 4x4. It has a terrible Knocking noise coming from the passanger side of the motor. this is the second engine in the truck and im worries that its the crankshaft. But i have been told it is the timing chain so im in process of changing the chain and the guides out but im not sure if its gonna fix it any suggestions ???
