The front hubs and the brake drums should be replaced with the factory approved replacement units (F3 hubs). For the vehicles that need the parts around the front hubs to be replaced to install the factory approved replacement front hubs (tractors with ABS of 'The Great'), the knuckle spindle assemblies should be replaced, too. Incidentally, it is likely to take some time to supply all the necessary parts, so as a temporary measure, an inspection for cracks should be carried out, and items with cracks should be replaced with the factory approved replacement units, while items without cracks should be replaced with the factory approved replacement units at a later date.
