The two main bushings are a standard size and avalible from any bearing dealer. The seal is avalible from NAPA or a bearing shop. The inner bushing in the cap is a odd sized is not avalible any more. The ID is standard, the OD is the odd size. If the small bushing is not worn to bad I would leave it alone, the two big bushings take 90% of the load and are easy to change out. Joe
