Ford Falcon ef rear diff/wheel noise

Hi there,

First check the diff oil level, check for oil leaks around the rear wheel bearings, (at the end of the diff housing) check universal joints foe excessive movement, A diff bearing noise will normally be fairly constant with road speed and throttle setting, they will change noise pitch when you come on and off the throttle (normally) wheel bearings will howl at a constant rate, regardless of throttle load, also make sure that the brake caliper has not come loose, another common problem is that the hand brake cable & or caliper actuator sticks on, you should be able to move the lever on the rear of the caliper (handbrake actuator) and it should return with the spring to it's off position. There are a few things for you to check.
