As Vampirex, I had a terrible clunk on my new +8. Such that if it could not be fixed I would have sold it. it went back to the MMC where I had the "they all do that sir". After a bit of back and forward arguments, the MMC seemed to through go through an attitude change, checked the wheels and found one outside manufacturers tolerances and 2 on the limit, they swapped all 5 of the "indian" wires for the then brand new stainless wheels and the problem was fixed never to return. Extraordianry service from the MMC.
