2002 ford ranger - Where is the 4x4 actuator located

On the transfer case
Transfer Case - Electronic Shift
The four-wheel drive electronic shift-on-the-fly feature electrically shifts the vehicle transfer case between 2WD, 4WD HIGH, and 4WD LOW. The system mode is selected by the operator through the mode select switch (MSS) on the instrument panel. The operator is informed which mode the system is in by two instrument cluster indicators: one for 4WD HIGH which appears as 4WD, and one for 4WD LOW, which appears as 4WD LOW. Shifts into 4WD HIGH can be made at any speed. When shifting into 4WD HIGH with the vehicle stationary, tooth blockage may occur preventing shift completion. When the vehicle is driven above 8 km/h (5 mph) the shift will complete. When shifting in or out of 4WD LOW, the four-wheel drive (4WD) control module requires that the vehicle speed be less than 5 km/h (3 mph), the brake pedal be applied, and the transmission be in NEUTRAL (automatic transmission) or the clutch pedal be depressed (manual transmission).
The gearmotor encoder assembly is mounted externally on the transfer case. It drives a rotary cam which moves the mode fork and range fork within the transfer case between the 4WD HIGH, 4WD LOW, and 2WD range positions.
The four-wheel drive (4WD) control module controls the gearmotor encoder assembly that shifts between 4WD HIGH, 4WD LOW, and 2WD modes.

I have a 93 jeep Cherokee, it will move in 4wh and in 4wl but will not go back into 2wd?

Hello guy
try posting what 4wd system you have,? first.
command trac or select track, (the latter is full time)
part time or the full time system,
we cant guess it....
read the operators guide first, if a part time system only
as i suspect, stop driving on dry pavement.
it's only for ice, or dirt. part time. part time is not a full time system.
shifting to 4wd on dry (means no ice) pavement causes, drive line wind up! and the gears to lockup. (see steering get tight in turns?> and is dangerous to drive it like this , you, me and the box)
posted here 100s of times.

the non grand Cherokee. early

had these choices
  • 1987-2001: New Process NP231 Command-Trac, part-time only, 2.72:1 ratio with low range
NP231 has the following settings: 2HI, 4HI, N, 4LO
  • 1987-2001: New Process NP242 Selec-Trac, full-time or part-time, 2.72:1 ratio with low range
NP242 has the following settings: 2HI, 4 full-time, 4 part-time, N, 4LO

as you can see you need to first know, what NP box you have or
photo your shift lever for 4wd, an post it and we tell you.

more facts, on select trac. (totally unlike command trac)
Selec-Trac locking hub is used on 4WD Cherokee. Selec-Trac
utilizes a non-disconnect front axle. Engagement of 2WD or 4WD is
accomplished at transfer case by means of mechanical shift linkage.
System allows full or part time 4WD. Selec-Trac can be shifted into
2WD or 4WD modes from inside the vehicle at any speed.
next from the service manual,
1) Place mode select switch in 2WD position. Transfer case
should shift to 2WD and not allow shifting into 4WD or LO range. Axle
should shift after transfer case shifts.
2) To determine if front axle has completed a shift out of
4WD into 2WD, position mode select switch back to 4WD position while
operating vehicle at slow speed. If vehicle shifts into 2WD, axle will
ratchet. If shift is not completed, transfer case will shift into 4WD
and hissing sound will come from mode select switch.
end quote.

if unsure read the FSM book its free.
shows you both systems and how to diagnose it.

in the box, click Cherokee,,then click 1993, and behold.
the real deal.

I have an 96 grand jeep cherokee and it is currently stuck in 4wd part time. When i shift it to N and put it in 2wd then shift to drive it does nothing but make a humming type noise. same thing happens w/...

first this is a shift on the fly system which means you shift it in and out of 4wd when moving and not stopped . 4 low yes stopped. second the diameter of your tires must be all the same plus or minus 1/8 inch. third if you drive in part time you will be causing binding when turning at all on dry pavement. this can break things like cv shafts and or the transfer case chain.

Installed new 4wd actuator in 2002 F-150, hooked up vacuum lines, but 4x4 light does not come on and 4wd does not engage. Is there a little bit of time for vacuum to build, or did I do something wrong. ...

Transfer Case - Mechanical Shift On The Fly (MSOF) Operation The mechanical shift on the fly (MSOF) system is a manual shift 4WD system that allows the operator to chose between two different 4x4 modes as well as 2-wheel drive. The operator can switch between 2WD and 4H mode at speeds up to 88 km/h (55 mph). To engage or disengage 4L range, the vehicle speed must be less than 5 km/h (3 mph), the brake pedal depressed, and the transmission must be in NEUTRAL.
Shifts between 2H and 4H can be made at a stop or any forward speed up to 88 km/h (55 mph). At temperatures below 0°C (32°F) shifts should not be performed above 72 km/h (45 mph).
The transfer case is equipped with an electromagnetic cluch which is located inside the case. This clutch is used to spin up the front driveline when shifting from 2WD to 4x4 mode at speed. When the manual shift lever is moved, this activates the 4WD indicator switch, 4WD electric clutch relay, and the electromagnetic clutch. When the transfer case front and rear output shafts are synchronized, the spring loaded lockup collar mechanically engages the mainshaft hub to the drive sprocket. Finally, the front axle collar is engaged and the electromagnetic clutch is deactivated.
