Thanks for the replies. I've checked and I can't see them fouling on anything. Just took it for another drive and after the drive the caliper had a slight but of smoke coming from it? Do you think it could be sticking like suggested. If so is it a trip to the mechanic?

Been busy with things. But got hold of some 17inch alloys with tyres all the same size. Fitted them and that's sorted the knocking noise. 🙏. A new problem has started. The front alloys are getting very hit to the point I had to pullover as the smell was strong. Anyone have any ideas to what this cou...

Thanks for the reply.

So would you recommend getting for 215s? Also any recommendations.

Thanks

Just seen a mechanic and hes advised to change the tyres first and see if that makes any difference as he's noticed the different sizes between front and back. Could be causing problems with the diff as it's 4wd?

Does this make any sense. If so what size tyres should I be looking for?

I've had a look under the van. No signs of bulges on the wheels. The propshaft looks ok. Can't seem to see any parts broken or warn? Would there be any other signs that it's the propshaft or is there anything else that could cause the knocking.?

Thanks for replying. It's road speed. When you say take a look around the wheels and prop shaft. What exactly am I looking for.

Hi all.

New to this but here goes. Drove home from Dawlish yesterday and noticed when I hit 40mph a loud knocking noise. The noise continued if I accelerated but if I kept the speed below 40mph it didn't happen. Anyone have any clues to what this could be? I have a 2.5 diesel.
