Hi, I have a Volvo 98 940Turbo estate having run 168.000 km and in very good shape except for one problem. There is a 'chup chup chup' sound from somewhere at 8 km/hour in both 4.th and 5th gear. The sounds are strongest when going up-hill and are heard of less with the car loaded. I've heard exactly the same sounds in another similar car, but no-one has been able to find the reason or remove this problem. Anyone here who knows better ? Regards Erik Rytter
