Do you have a dwarf in the boot

Seriously, what does it sound like? is it a regular knock like someone at the front door, or more like a loud click?

I have no idea, have you checked the bolts holding the diff on? Mine clunks when I first reverse it out of the garage and then its fine, the clunk does sou nd like a knock though.

Not being stupid but have also heard of the roof struts coming loose and making a knocking sound.

My guess would be the exhaust knocking on something.

Mine did this when the diff bushes went, also found that the diff mounting brackets were almost cracked off and were flexing. Is the knock speed related, ie, does it get faster when you go faster etc?
