Ha ha ha....I like the "its when your car is quiet you should worry, then something probably fell off" :-)
Planenut....thanx for good advice!! I have just skimmed the surface but the Alternative Parts List is a true goldmine!!!
As soon as I have changed the oil (redline shockproof gear oil) in the bevel box I will take a test drive again and try to locate the noise (without the cover and rear hood)....All your tips and help is really appreciated!!
Thanks again...
