What does a viscous coupling sound like, other than expensive, when it is giving up driving the front wheels? I know mine is on the way out but now when I pull away I get a noise like a dry bearing but only when I put the load on it. When I have started moving, like 1 kph, the noise stops. I have been racking my small brains to think what else is turning. I can make it do the noise by applying the handbrake and taking up the drive. I did think of the spigot bearing in the flywheel as it is turning up to the point of taking up the drive. So do viscous couplings make noises, oil level is fine and new and correct.
