realised why it's banging after I fitted the new clamp..... it had slipped off the bloomin' joint !!!
So I had to get the ramps out, and get dirty crawling underneath to try and get it back together properly and then get the clamp to sit right without falling out again!
Thought I'd managed to do it, including putting a load more gun-gum around the joint.... well, I've solved the 'blowing' joint
problem....
But I'm now getting a banging from where the back box is hitting the bracket on the car that holds the rubber exhaust mount near the rear beam.... ARGH !!!!
Need to find some way to alter the 'length' of the bar which supports the back box through the rear exhaust mount. That will prevent the back box moving to one side and hitting the bracket......
Anyone got a small blow-torch I can borrow ?!?
