Something ticking in my drivetrain

The reason that a bad bearing my only make noise while accelerating or braking is because those are the times when the drivetrain is under the most stress. As torque goes up during those times, a bad bearing will "distort" (I couldn't figure out a better word to describe it) and change the mesh in that area which will cause the grinding and ticking. Then when you are coasting (or going slow) there is less torque so the bearing is not being "distorted" and the mesh goes back to normal and the noises are gone.
The best way to check you bearings is to remove them one at a time and check the play between the inner sleeve (the part that spins) and the outer sleeve. If there is alot of play then it is toast. Also, spin the bearing and if it sounds or feels gritty then it is probably bad as well.
