just getting worse, front end roar seem to be in the right front when going down the road and gets worse when turning left at speed. Almost completely goes away turning right. Very quit at low speeds but gets worse with more speed.
roar in right front wheel area. on 2004 Pontiac Montana
Sounds like a wheel hub or bearing has failed and you can check wheel bearing replacement prices here http://repairpal.com/estimator?car_type_id=4098 and find a shop near you here http://repairpal.com/directory?address=72938&car_brand_names=Pontiac
It is probably you hubs. Been there. Replaced 3 hubs on van last year, so asked Dealer and said it is because of the slurry they now put on the roads for icy conditions.
its the wheel bearing for sure!!! ive got the same problem!
