I have a 1991 Chrysler New Yorker Salon only 39,000 miles V-6
When I am in a drive thru- for example at the bank - and I am stopped - but leave it in drive - I hear a loud rattle. However, if I shift into Neutral or Park - while I'm waiting - the rattle goes away. When the car is moving - the rattle goes away.

Could this be a bad universal?

Not logical, There would be constant pressure keeping a loose joint tight when it is in gear. Would you describe this a tinny rattle. If so there is probably a heat sheild loose over the converter. tap the exhaust with a rubber mallet and you may be able to track it down.

Suggested Repair

A bad universal joint is unlikely, because load in gear would keep a loose joint tight. If the noise is a tinny rattle, check for a loose heat shield over the catalytic converter and tap the exhaust with a rubber mallet to locate it.

The owner asked whether a bad universal joint could cause it. The expert said that is unlikely and suggested a loose heat shield over the converter, which can be tracked by tapping the exhaust with a rubber mallet.
