What causes suspension clunks in the Renault Laguna?
Our 2005 Renault Laguna recently passed the NCT (first time surpisingly enough for a Renault!). About a month after the NCT the suspension on the rear passenger side started making clunk/rattle noises going over potholes and bumpy roads - what is the main cause of rear suspension noise in Lagunas?

Hi Don,
Ah, a familiar problem this one, especially to anyone who's owned a second generation Renault Laguna (yes, that's my hand up). It's most likely that the clunking noise is coming from the top suspension mount, which is a spectacularly weak area on second generation Lagunas. It's not a massive job to replace but get it done now before the mount breaks and takes other expensive items with it. In extreme cases, the noise could be coming from a broken spring, but if that were the case you'd probably notice the car sitting lower to the road on one corner. When you're getting the work done make sure the garage checks out the other suspension mounts as if one's one the way out, the others could be too.
