Unexplained Banging

[Fletch]

Nope not the neighbors night in but from the upper dashboard/tip of the screen area.

I changed the anti roll bar bushes a week ago and after a few days there was a knocking again, gutted i thought maybe id placed the bushes a little off or something.

I spent the best part of a day re positioning the bushes lobe up and down no effect still banging, went over the whole front suspension checking for play and all good but still the knocking persisted.

Medium knock over loose ground which then gets very heavy knock on say a small pothole like somethings going to give.

Finally removed the wiper mechanism and scuttle and was instantly greeted by the nut and shaft of the front right shock absorber , it had burst through the suspension top mount penetrated the underside of the wiper scuttle (unseen when together) and was in direct contact with the mounting nuts hence the heavy knocking. 

Totally unexpected and after replacing the bushes assumed it was something id done, anyone else had it? genuine top mount but how old is anyone's guess the car is a 2.5 crd with 144k on the clock.

I've got the same issue but isn't as bad, common problem apparently.

I had that I replaced the anti roll bar/sway barbushes with blue poly bushes after test drive on uneven ground was still clunking after having a mate rock it while on ramps the drop link on drivers side had given up apparently common if anti roll bar bushes aren't done quick enough

I may have the same deal, basically going on uneven ground or hump, you get a bit of a knock, low sounding knock. On the motorway it's fine. Always been there, was hoping the mot may shed light on this one. But it did not. You can't emulate it stationary and rocking the car or bouncing it. Only when in drive and the ground is uneven.

On the mot, there was the slightest of play in a pin/bush on the drivers side on one of the suspension parts, it doesn't sound like this is the cause, but possibly. Who knows..
