Finally got my local dealer to have a look at the motor this morning. After road testing it and having it in the garage for 2 hours, they have asked me to bring it back in on the 5th May so they can spend more time on it. They have tried lubricating & tightening all relevant suspension, steering bolts, exhaust heat pile shields, greased roll bar/suspension bushes, but still the noise is there. What is strange is the fact that when it is cold & so is the weather it doesn't make a creaking noise, but the more you drive it, the louder the creaking becomes & it happens more frequently. I've also noticed now the days are getting warmer it is getting worse. Very strange indeed!
I personally think it is the steering rack because my steering wheel doesn't return to centre either, but we shall see!
Roll on the 5th because this creaking noise is doing my head in!
