| Description of the problem | The clutch pack in the driven train rear differentials lock up when turning corners and howls when going down the road. These failures are so common on ford truck that ford is now adding friction modifiers to the rear differentials to rear the problem and aftermarket suppliers are making replacements for the clutch pack like detroit locker to eliminate the problem. This lock up on winter surfaces cause the wheels to loose traction increasing the potential for accidents. The howling sound is also a drag on the drive train components, reducing mpg and capability of the vehicle to handle adverse conditions. Ford has known about this problem for several years and has done nothing to fix the problem or reimburse owners for the cost of repair. On my truck, total rear end repair costs have exceeded $3700. |
