All, I'm after some advice if that's ok? My tintop is currently in the garage, and they're looking for the grinding noise on acceleration and breaking. The thought at the moment is that it's the Powerflex bushes creaking, but they're really unsure. Is there any way of quickly proving that, for example if I douse them in WD40 and then go for a drive? Or is there a safer lube I can use on Powerflex bushes?

I can kind of see where they're coming from if the bushes have dried out, but I don't want to strip them down and regrease them if there is a quicker way of proving it.

We had creaky problems witha new Saab - they used silicon spray to quieten it down.
