Hi everyone - changed gearing from 1.2 to 1.4 on my 300tdi 110 and the noise appeared - louder the faster the vehicle goes - over and above the engine noise. The garage - who I have used for many years and are very experienced - took it back and opened the transfer box and re-did it - but the same noise. Has anyone any ideas please. The box has done 2,000 miles and was purchased from Ashcrofts about 18 months ago and the replacement gearing came from them also - they have no idea what might be wrong. Am about to have the original gearing put back!!!.
