If you checked all the various bushes then my money would be on the shock. You could swap them side to side and see if the noise follows.

I had the same knocking rattling on my last van and put new shocks on and it wasnt that, changed the pads thought it was that but it wasnt. could my ARB be worn out at 100,000 miles?

I have a rattle too I’ve done arb links bushes , shocks , pads , I thought I’d sussed it yesterday I found that if I thumped the fuel tank I got a rattle that sounded just like it , if your lying under the back of the van looking up at the tank to your right side there is a brake pipe and sensor wire that disappears over the tank the brake pipe was sat on the tank , RESULT. No it’s still there 😡.

I had a minor annoying knocking, so asked my mate to drive a van while I sat in the back, trying to locate where the knocking coming from. And it turned out to be the bottom barn door catch. Adjusted it by 0.5mm and the knocking gone.

Ohhh I’m on it , did it knock just rolling, I can just roll down my road which believe it or not has no potholes and it will knock, very slight but constant , I’m gonna check wheel bearings too I think , doing me head in 🤨

Peely we are both in the same boat, knocking wise, yours sounds the same as mine. It is doing my head in too.
