It has been few years since I rebuilt swivels and have only ever done it in the past where I have replaced the swivel as part of the rebuild kit. Looks like I will need to replace the top bush (old style front axle) do I need to remove the swivel ball to replace the inner seal or will it fit over the ball once the bush is removed? I know people do, but I dont want to, split it and glue it back together when just replacing the seal, but I will be partially stripped down anyway.
