Roaring???
If the noise doesn't bother you I wouldn't worry about it. Half the people on this board prolly have this condition. If it does, pick up a rebuild kit. if your noise is that bad you might have to buy a new axle and bearing... I had to do this when I got my TA, and the yard I got my used axle at said it was common, they had a mountain of old scored axles in back....
all in all a pretty simple problem to either fix, or have fixed. good luck.
If yours is making noise while accel and decell than you have a carrier or pinion bearing bad. You can get a bearing kit w/shims for about 100.00. I would replace all while I was in there. Just my .02.
