Oil leak?

[Claymore]

The steering rack gaiter will be located to the rear edge of the wheel and above.
I've just had that pleasure and when the leak starts, the fluid can be thrown about a bit by the airflow behind the wheel. You'd see evidence on the inner arch plus probably on the back of the tyre/rim.
But when you stop and park up, you'd also find the puddle directly below the track rod end.
Whilst researching my own problems though I found quite a few other owners talking about pipes coming off gradually and leaks at the underside of the PAS bottle etc.
You'll no if it's power steering fluid by the smell. Completely different to engine oil in my experience.
