The new B Series Backhoe Loader rear axles now have a new Caterpillar MTO oil available (105-3335). However, some machines have still experienced chatter coming from the rear axle. Brake chatter can be remedied by first ensuring that Caterpillar MTO oil is being used. If the chatter persists, it can be reduced by adding Ford Friction Modifier (251403 Ford part number), available from Ford. Some brake chatter can be expected.
