Not very exciting but replaced the rear gearbox mount (auto)... It has made so much difference! I have been putting up with vibration under load that always got worse in the cold and wet weather. I have been troubleshooting this vibration for ages and was thinking it was the gearbox, front shaft, tyres!
15 minute fix if you have a hoist, was a bit suprised it was worn as my car only has 130,000kms.
Part Number 1132001U01 for anybody that is interested.
Adrian.
