My 2007 rendezvous has a loud roaring noise when driving down the highway. What could this be?

Just had a wheel bearing replaced on my 07. Noise would occur while cruising at running speeds if I turned the wheel left no matter how slightly. Noise appeared to come from the right however it was the left bearing that was bad. COVERED BY POWER TRAIN WARRANTY NOT CHARGED A DIME

Could be simple as out of alignment or if AWD, mine made a loud roaring sound and I just needed to have the fluid changed in the rear end and that fixed it.

when you are driving, turn the wheel to the left and right and see if it stops for a second when you do that- if it does, it is probably a wheel bearing- if the tone changes with speed, your tires could be worn funny and that could cause the sound- the fix for that would be new tires.
