" Take a pressure pump, I use

" Take a pressure pump, I use a Mity-Vac one that will check either pressure or vaccum. drain the oil, install one drain plug in one hole, and a fitting that will be able to accept the hose from the pressure checker you are using. I normally pressurize the lower unit to 13-15 psi. Spray soapy water on all seals that you can see and into the hub, the soapy water will start to bubble were the leak is at. Then just replace the appropriate seal and you should be ready to go.

Hope this will help you find the problem. "
