Do they make a sleeve for the axle like they do for the harmonic balancer snout when there is a grove from the seal on it. Years ago I rebuilt a motor for a buddy and his harmonic balancer had a groove worn into the snout where the seal rubbed on it. Went to the auto parts store and the old geezer behind the counter told me about this metal sleeve you glue onto the snout and walla...good as new. My Dana 44 axle has a grove on the axle where the inner seal rubs. I've notice some slight weepage on that side also, nothing major though. Was wondering if they made a metal sleeve to fix this also?
