Rear End Rumble on 2003 Buick Century

#1

2003 Buick Century, the rear end of the car has developed a rumbling/
rattling sound when driving over rough pavement, especially at slower
speeds. On smooth roads, there is no noise, and I don't notice the
noise (as much) on rough roads at "non-slow" speeds. The driveability
of the car is not affected. A mechanic lifted the car and did a visual
inspection, nothing obvious jumped out to him (signs of rubbing,
something loose, etc.).

Any suggestions?

It could be tire noise also but I would suspect it is a rear wheel
bearing. It may not be possible to duplicate the noise on a lift.

A bearing would not give you a rattling sound. I suspect a strut
mount.

We have a slightly older Buick, and I can sometimes here a rumble from the
rear end when I park and go to the rear of the car. It is clearly
associated with
the exhaust system, and since it causes no problem, I have ignored it.

OK, the problem was found: the shop that recently did my alignment
forgot to tighten down a rear end tie rod.
