So the right, rear wheel bearing's on it's way out on the 5KCSTQ... It's noisy and the pitch of the noise changes with speed and wheel load. It IS the wheel bearing, right? What happens if I let it go for a while, it's probably been this way for at least 5K miles? BTW, any simple ways to repair it. TIA Michael Eck 86 5KCSTQ 88 GTI 16V
