hole on the driver side of the power divider housing which lines up with the fill plug is drilled through to the fill plug hole. This can create a path for a leak around the threads of the mounting bolt. The remaining five mounting bolt holes are blind. When a leak is found in this area, verify that all six mount bolts around the flange are tight. If any of the mounting bolts are found to be loose, the power divider lockout (PDLO) assembly must be removed and the gasket replaced. If all the bolts are tight, the bolt at the 3:00 position should be removed and cleaned along with the mounting hole with a residue free cleaning spray like contact cleaner.
