Borrowed my buddy's pressure washer yesterday and spent the afternoon blasting the engine compartment, and as much of the underside that I could reach while the car was on jackstands.
Here's the rear differential shots. The weird harness going to the pinion hub is actually a prehistoric version of ABS that would monitor the differential speed and pulse the breaks at an amazing (for the time) 4 pulses per second to prevent rear brake lockup. Unfortunately the valve component that sits in the engine compartment failed years ago with an internal leak and was removed and thrown out by my Dad's favorite Lincoln dealer...
Gotta love that old blue Permatex attempt at sealing the leaking pinion gasket by the same Lincoln dealer.
