if its a front wheel drive vehicle then it could be the axels
could be a wheel bearing...or just that its a french car
it could be a rock or your cars not funny
The grinding noise in the front of a 1990 Dodge Caravan could be a cv joint. If it is, it probably only grinds when you take a sharp turn. There is one located on each side.
If the grinding sound seems to be coming from the speedometer and grinds faster as your speed increases, the likely cause is the speedometer cable. At least some 1990 Dodge trucks (mine) have electric speedometers Len
Fuel is not good!
Get your car to a garage immediately! No car should be making any grinding noises while driving. this may suggest a slipping clutch, faulty brakes or maybe even damage to the piston and combustion chambers. it could be either of them which is why this needs to be fixed as soon as possible.
Could be a number of things. Is the noise coming from your transmission, your rear differential, one of the wheels? From the wheels it could be a warped rotor or a wheel bearing failing.
check the guard behind the rotors could be rubbing
Is it from the wheel? If so, then it could be numerous of things: worn hub bearings, worn brake pads/shoes/rotor, faulty drive axle...listen carefully and take you car to a certified mechanic!
you need to have the engine tuned on a machine by the mechanic, the timing could need reset. Also, Dodge Magnums have an anti-slip mechanism which if engaged, cause this sort of lag. There's a button on the dash you can disable this feature with.
