The problem
VEHICLE DESCRIPTION: STEERING AXLE BRAKE DRUMS, PART NUMBER 61958B, USED IN AN AXLE ASSEMBLY COMBINATION SUPPLIED SOLELY TO BLUE BIRD BODY COMPANY BY WEBB WHEEL. THE BRAKE DRUM IS OVERSIZED IN THE AREA ABOVE THE MOUNTING FLANGE AND PREVENTS THE DISC WHEEL FROM MOUNTING FLAT AGAINST THE BRAKE DRUM.
Risk
PROLONGED EXPOSURE CAN LEAD TO DISC WHEEL CRACKING AND SUBSEQUENT DISC WHEEL FAILURE. THIS COULD ALSO LEAD TO LOOSE FLANGE NUTS AND LOSS OF A WHEEL IF NOT DETECTED.
What owners should do
WEBB WHEEL WILL REPLACE BOTH STEERING AXLE BRAKE DRUMS. ALSO, IF CONTACT IS PRESENT BETWEEN THE BRAKE DRUM AND THE DISC WHEEL, BOTH STEERING AXLE BRAKE DRUMS AND BOTH STEERING AXLE DISC WHEELS WILL BE REPLACED.
