Loud knock from underneath

Having all new poly bushes fitted myself as I had exactly the same problem myself :/

looking forward to not hearing that thump every time I try to move off from stationary believe me it gets worse over time!

I think I just might have embarrassed myself big style. I spent quite a while under it yesterday trying to find anything that could be the cause and found nothing at all. So decided to rely upon the upcoming MOT trial run to find it for me.

However, this morning when I finished work and went out to it in the car park, I took off my clutch claw as usual and put it in the space between the seats where I keep it. It slipped out of my hand and struck the bulkhead behind the seats and made the EXACT noise I've been hearing. This is when I realised that when I was tidying up the inside a week or so ago I had hung the cloth thing that is dangling from the bulkhead behind the seats over the top behind the bulkhead. So I tested it out and I actually watched the clutch claw tilt forward on heavy ish braking and come to rest against my Eberspacher, then as I accelerated away it fell back and thumped off the bare bulkhead, the noise, I am positive, has now been identified. I feel a proper ****T, but am promising myself I'll rule out loose items the next time I hear anything like it again.

Assuming that this was the cause, I wish more "repairs" were as easy as this one!

it can happen i had a well known lr parts man from bradford who i had reconned front axle came over to me to check axle as he had clunk on braking,and it was apple in box under seat on 110 rolling baxck and forth,iam not sure whether he was more embarressed or me relieved

Now that you mention it - I had something similar years ago and it turned out to be my jack rocking back and forth - that makes me feel even worse 'coz I should have known to check the INSIDE.
