Uuummm, no, the PT and FT explainations are wrong. PT means that the
centre diff is locked, and that since everything is locked together it
will cause the driveline to bind if you turn sharply on dry/hard
surfaces. Its to be used "part time" only, in slippery conditions where
the wheels can slip when turning. FT is designed to be used "full time",
and has slippage in the centre diff so the driveline won't bind up when
turning.
