Are you sure the shaft isn't worn?

Sounds to me like you have either the wrong seal or too much pressure inside the unit.  A seal is usually a weak point in holding fluid in place, and a point prone to leakage. 

 

Make sure the rubber is rated for hydraulic/hydrostatic oil, too.  It is rough stuff on rubber.

well after 4 hours on the internet i finally found the seal.the size is .750x1.316x.250.the timken number is 480821.believe it or not these are pretty common for auto power steering shafts.
