Rear noise
 
I have recently noticed a thud noise from the rear NS(RHD) when going over bumps, seems to happen when its cold. Once its moving for 15-20mins the noise goes. Its an 88 Euro spec, the geo was done about 4 months ago.

Checked the ARB(sway bar) mounts, shock mounts, drop links - All OK as in tight.

Engine mounts?

Heat seems to be the differentiator here - do you have a loose heat exchanger or muffler mount? Have any recent encounter with a speed bump or otherwise?

Agreed heat is the differentiator, I checked all the exhaust system and its good and tight.

I have noticed the NS engine mount is slightly out http://forums.pelicanparts.com/uploa...1284044358.jpg
