Clonking going over bumps

[GrahamS]

Now I know there are loads of threads about knocking and it being the top mounts.

I have this clonk in the DCI when going over bumps at any speed above about 10. In other threads I've read about it being when you're on full lock etc but nothing about speed.

ARB bushes and links are new.

Is there anything else it could be if it's not the mounts?

If it is the mounts which specific bits need replacing. I know you can put a washer in but I would like to go to the root cause.

Cheers boys and girls

Engine/gearbox mount, driveshaft, other suspension part, loose battery. The list is quite extensive unfortunately.

if its a metallic type loud ratteling sound check the front calipers as well... replaced most of my suspension trying to sort out the noise on mine, ended up beeing worn guids on the calipers... take the wheel off on the side the noise is comeing from, of if its from both sides then take any one off, give the caliper a smack with the side of your hand... if it makes the noise ur hearing then u found your problem... the agents told me it was a common problem, could have been avoided if they bothered to re grease the slider pins and put the gaters back... check for excessive play in the caliper and on the wishbone, steering rods... some play is needed on the caliper and bushes but not a huge amount.

if its not the suspension then as said above... could be a number of things...

Could be a shock, I replaced mine and the noise went.

Thanks for all the suggestions. It's not a metallic noise and I checked and greased the calipers recently.

This is the best video I can get at the moment. It's at about 12 seconds when I go over a bit of rough road. In real life it sounds deeper and less rattly. It's more of a quick thudding when going over a bump.



Could be a shock or mount certainly. Can you test a shock?

 

[l33th3tr33]

That sounds healthy. the only way I know to test it is find a hill with a turning on whatever side it's on and turn in coming downhill putting the most force on that corner of the car and it will make the horrid noise. Don't go mad, I turn into my road very slowly as there's a load of pricks round my way driving like bells, and it still did it.

That or a speed bump on that side only?

Happens when either wheel hits a bump and isn't affected by turning.
