I have a knocking in the front of my motor at idle, it gets louder when I turn my wheel or apply my brakes so I'm thinking vacum pump. When I drive you can't hear it , and it does'nt get louder as my RPM's increase so I don't think its a rod... Can anyone confirm this, has any body got a knocking noise from a bad vacum pump or anything else that could cause this....

Also it threw a check engine light when I limped it home from work...


Any Help Is Appreciated,

Fill in your signature with your truck details so we know what you have.

 

It is a 2001 dodge w/ a 02' motor and 03' 6spd tranny...

 

I belive we found it a tooth broke of the drive gear on the vacum pump and has been bouncing around in thier, I'm going to have to take the timing cover off to see what else it broke...
