yeah those rub marks are normal mate - they're already on the beam axles sitting in stillages fresh from futuris.
From the one car I've managed to investigate so far the root cause is not the handbrake cable (I wish it was that simple).
However, more info is generally a good thing, so still hunting. schmick I'll be in touch
I am by no means an engineer, but I have noticed the exhaust moves around a fair bit on these utes from new. What seems to be happening is that at a certain RPM, the viabration/resonance cause by the exhaust has an affect on the handbrake cables.
When the car is cold and has a slightly higher idle, there is no noise. Once its warmed up and idle is around 600rpm, it makes the noise. Seems to be the worst with the AC on.
It goes away if you pull the handbrake up.
Call Strapp Ford in Burwood and ask what they did to my car.
The problem is 100% gone
