MX NOTICED UPON REMOVING LT WHEEL BEARING CAP, ANTI-SKID DRIVE COUPLING TANGS SHEARED OFF. WATER WAS ALSO OBSERVED DRAINING OUT OF WHEEL SPEED TRANSDUCER HOUSING. CLEAR THAT WATER IN AXLE HOUSING FROZE WOULD NOT ALLOW WHEEL SPEED TRANSDUCER TO ROTATE. THIS WOULD SHOW ANTI-SKID SYSTEM THAT LT WHEEL WAS IN A SKID AND SYSTEM WOULD NOT ALLOW BRAKE PRESSURE TO BE APPLIED TO RT BRAKE. A NEW TRANSDUCER WAS INSTALLED ON LT WHEEL, COMPANY CONVENIENCE. RT AXLE HOUSING FOUND FREE OF WATER.
