Play in the rear wheel can also be bad suspension bussings, I know because I have alot of play on my rear wheel and I know some of my bushings are bad and the wheel bearing. If you watch your caliper while wiggling the tire, and the rotor and wheel are moving but not the caliper you know its a bad bearing. you can just watch the area around the bushings and you will see it move when its the bushings. Its funny though that its your rt rear bearing thats bad, because my rt rear is bad and a friend of mines mk3 he just replaced the rt rear a few weeks ago.........I wonder if its from all the counter clockwise donuts we do? :evil2: , you ever try to do donuts the other direction?, it feels wierd.
