[V8] front locking diff

[dsaad at icehouse.net]

Are you sure about front diff locking?
I am not aware of any non-military vehicle with a locking front diff.
(of course I am not aware of a lot of stuff :-)
Lots of people put them in themselfs, but this is usually the hard core off road
types. All of these 4WDs (owned by me) - 1988 Bronco 2, 1983 Ranger, 1993
Explorer, had severe driveline lockup problems if you tried to turn on dry
ground in 4WD. The front end would hop up and down.
These vehicles did not do that - 1971 Jeepster Commando, 1998 Explorer, 1999
Expedition.
They ALL had open front diffs, and the Explorers and Expedition all had locking
rear diffs. The difference is the old Jeepster and new Fords have constant
velocity joints at the front hubs.
With that you can actually do a U turn on dry pavement with a lot less driveline
twist up. It is still really hard on it though.
