Banks Exhaust Brake Squeak?

[PhillipK]

Hello experts,



I've got a Dodge 2006 2500 with 26,000 miles and has developed a brief whistle or squeak when accelerating while using exhaust brake. This occurs at the exact time fuel is being given to the engine and the exhaust brake is being opened.

Squeak or whistle is not heard with braking system turned off.

Maybe pivot point on the Banks exhaust valve/flapper?

Any thoughts out there?

Thanks, Phil
