I know this is a problem with the stage2 - not sure if welding would only be putting it off as it will happen again (or it`ll then fail internally like kennys + mine did)
one hangover, one pair of ramps, very basic tools and under-tray off
(spray painted the under-tray while I was at it using some satin black Hammerite god it looks sooooo much better, why don't they do that as standard?)
then using some brute force and ignorance I just bent the offending brackets out of the way so there is now no vibration and it sounds like it should, ie just bloody loud without any other annoying noises
