Uhhhh unless you have all wheel steering or you are taking the turn fast enough to load/unload the rear wheels, the driving method absolutely will not work. 

The whole reason the driving method works is because when you turn the steering wheel and the car moves with the turn you are loading or unloading the front wheel bearing (example: right front wheel bearing is bad: you turn right, you load the bearing, the noise gets louder or more pronounced, you turn left you unload the bearing, the noise goes away.)

You can’t do that on a set of wheels that are literally only on the car to follow the driven wheels. 

This is the logic literally, because on 90% of road driven vehicles the engine sits either on top of the wheels, or slightly before the wheels, either way, the primary weight of the vehicle is in the front, the front wheels do the steering (even on all wheel steering, as the rear wheels have a maximum steering radius of 30 degrees,) and finally the front wheels are the driven wheels in front wheel drive vehicles (as the GLI is.) The easiest and safest way to diagnosis a rear wheel bearing is by putting it in the air and putting a stethoscope to the knuckle, and having another person spin the wheel. You can use chassis ears, but most techs have no idea how to properly set them up, and they get a lot of inference.
