The grinding sound when accelerating could indicate a worn-out CV joint or a problem with the transmission. The loud whirring noise at all speeds could be due to a failing wheel bearing or an issue with the differential. The higher engine temperature than normal could suggest a problem with the cooling system, such as a failing water pump or a blockage in the radiator.
There are several things that can cause your 2002 Ford Taurus to hesitate when accelerating. A dirty air filter will cause the problem.
Loss of power when accelerating can be caused by a number of things. A leak in the fuel line or even a bad alternator can cause this.
Hi, it sounds like a faulty wheel bearing on the passenger side (not a difficult repair), but could also be a CV joint although they usually click when worn out. Ray
If rear differential noise occurs while accelerating the car only at a certain speed, it is likely because the gears have become worn due to overloading and lubrication failure. ... Rumbling and whirring noises at speed over 20 mph, moreover, can be the result of worn carrier bearings.
Fuel is not good!
I have the same problem i think in mine. Turns out that whirring soundd is my a/c compressor. Have to replace. Check and see if your a/c works
Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
A clicking noise, when accelerating, can be caused by a worn CV joint. The CV joint can cause the axle to collapse when it breaks.
A bad wheel bearing
A constant force in the direction of the line
