Rear-Bearing problem maybe.....

[cxt2001]

Im so screwed....here is the deal I just had my tires rotated and I made a 5 hr trip to fla. and i noticed on the way down there that the right rear seemed to be making a loud rurrrhh'ing noise that was a pulsating noise. Now that im back at school when i drive it i noticed it got worse, now it is so loud and its a real loud pulsating noise thats even vibrating so plastic parts in the back by the speakers. And i was planning on going home this weekend for service. But now im afraid that it wont make it. My dad thinks it could be the rear wheel bearing. And he thinks it could seize-up. (And no its not the tires) If anyone has had this problem please let me know what to do. Thanks.....
