I HAVE A 2004 DODGE RAM 1500 THAT MAKES A KNOCKING NOISE WHILE RUNNING AND SEEMS TO GET LOUDER WHEN ACCELERATING. I WAS WONDERING WHAT I SHOULD DO ABOUT THIS?

Hi:
Is the knocking sound coming from the engine? If so, it could be a rod or main bearing in the engine. Make sure the oil is full and clean. Also, keep an eye on the oil pressure. It really shouldn't run (at an idle) lower than 10 PSI and max at 60 PSI at highway speeds.

Let me know what you find.
Joe

The noise isnt coming from the under the hood you can only hear it when you are standing next to the D/S door or next to the P/S door. I just changed the oil when I just bought the truck a month ago, I read in the manual and it says that if you dont run a higher grade of fuel through the truck that you will experience a fuel knock. Thanks for the feedback. Darren.

Hi:
The knock they refer to is usually experienced under a load when accelerating. However, I could be wrong. The fact that you don't hear it under the hood indicates it's most likely not the engine. It could be something between the trans and engine, torque converter, loose flywheel.

Regardless, I recommend you have it listened to by a mechanic. See what they say.
