Hearing some noise when engaged in D

I am hearing some noise when I stop at a traffic light or somewhere(engaged in D), but when the car is in idle (P or N) the noise goes away. I already changed a supercharger coupling, but the noise didn't go away. Could you please give me any advice. Thank you for any help.

Can you describe what the noise sounds like?

It makes a lot of racket, and It sounds like jingling. When I am driving, the noise goes away. But It happens only when I put on D and drive slowly(when make a turn or stop at traffic light).

Harmonic Balancer pulley

Try to see if you can get the noise to happen while rolling in N. That should rule out the transmission. Turn the engine off while rolling. That rules out the engine and harmonic balancer.

With engine off, push the car back and forth in N and listen from the outside. See if you can tell if it's coming from the left or right side of the car.

Tire/Wheel Rub - make sure nothing is rubbing against the wheel well or brake system.

Springs/Struts - do a quick visual inspection to be sure a coil isn't broken, or a strut blown out.

Hubs/Bearings - lift a wheel off the ground and push hard on the tire at 12 and 6 o'clock position. Test for movement. If it feels sloppy, the hub needs replaced. About $125 for the part.

Wheel Lug Studs - check lugs are not missing or broken. If needed replace the bad stud.

CV Axle Joints - inspect CV boots for damage or leaking grease. If you see any grease sprayed in the engine bay, replace/rebuild the CV axle with a new or used one. With the car lifted, you can go under and watch/listen for noise as the wheels are turned by hand.

Good luck!

Please check your motor and transmission mounts. Any that are not a "cross" or " + " shape when at rest are worn out and need to be replaced. Most likely you need the front and rear transmission mounts. Most likely you don't need the front upper engine mount. In my experience the mounts only last ~80 - 100 thou miles/6 years or so.

Thank you for any comments. You guys so awesome. It is Harmonic Balancer pulley. I changed it and the noise goes away. I am very happy now. thank rivperformance board again.

You are welcome and check your motor mounts anyway. All that vibration likely will have wacked them.

Wow, nice call Klix!
