My 98 2.5l/ATX Contour is making classic differential bearing noise - rumbling up through 50-60 KPH, decreasing in noise and then with a slight higer pitched howl abouve 90 KPH. More noise on turns and when braking (Wheel bearings and rotors are all new). Now the transmission has always had a significant buzz/vibration in it when accelerating from rest even when under warranty (have 169KM now)which I assumed was wheel bearing problems. Vibration was felt through steering and through gas pedal as it is now with some noise. I took it ind for service and even when wheel bearing were replaced under warranty I complained to the service rep at the Ford dealer at the time that vibration was still present at low speed. The answer back at the time was that my snow tires tread configuration was the source of the vibration which I disagreed with but did not press as vibration was transitional.
Now that the vibration is getting worse is it worthwhile or even feasible to go back to the dealer and complain for Ford to do the work it should have done when under warranty. It may be a long shot but worth a try. However if they turn me down do I still have Ford replace the tranny or go to a transmission shop and if so which ones are good (in Toronto area) Any experience GTA people?
