FORD 2004 Ranger v.1 - Manual (Page 131)

If a distance of 80 km (50 miles) or a speed of 56 km/h (35 mph) must
be exceeded, you must disconnect the front (4x4 only) and rear
driveshafts. Ford recommends the driveshafts be removed/installed only
by a qualified technician. See your local dealer for driveshaft
removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid or transfer case fluid loss, damage to the
driveshaft and internal transmission and transfer case
components.
