The CE Smith Trailer Hub Assembly # CE13315 is the correct replacement hub for your EZ Loader trailer. This hub has the same 5 on 4-1/2" bolt pattern, using the Bearing # L44649 and Grease Seal # 34823 (1.249" ID). Your hub will have a threaded cap while this one will include a standard grease cap. You can upgrade this to the Bearing Buddy Bearing Protectors # BB1980A-SS to easily fill your new hubs with grease without overfilling them and blowing out the grease seal.
