Check the wheel bearings. My Regal did the exact same thing when one of the wheel bearings went bad.
You can check a number of problems using the following method.
Jack up the car and grab the tire while it is still bolted on. With your hands at the 3:00 and 9:00 position, wiggle the tire left and right. If there is play, your problems could be:
1. worn tie rod
2. bad wheel hub bearings
With your hands at the 12:00 and 6:00 position, wiggle the tire up and down. If there is play, your problems could be:
1. bad ball joint
2. bad wheel hub bearings.
Eliminating either the worn tie rod or bad ball joint will help you narrow your problem to the wheel hub bearings, at which point you would need a new wheel hub.
The general consensus is that Timken wheel hubs are the best to use.
