I have a 97 Stratus and a few months ago the car started a humming
noise in the front end while driving, which gets louder the faster you
are moving.  The humming quiets down and/or stops when you turn to the
right and gets louder when turning left.

Here is a kit and instructions to replace the 2.7 engine with a 3.2 in
the Dodge Intrepid.
