Re: 1929 640 Differential leak

jimw, many times the pinion shaft - where the seal contacts it - will have a groove worn in it by the seal. Perhaps your leak is due to a worn seal and a groove in the shaft. A couple of bearing manufacturers make a precision sleeve (Speedie Sleeve?) to fit over the worn part of the shaft. This restores the surface preventing the fluid from leaking past the seal. Check with a good bearing vendor for the sleeve. The seal is probably available from some of the vendors known here. Others may have more specific information on this.
