Dodge 2008 Ram 2500 PowerWagon - Manual (Page 278)

rear axles are unlocked. In the REAR LOCK position, the
rear axle is locked. In the FRONT/REAR position, the
front and rear axles are locked.
NOTE: Even when the axles are in the AXLE UNLOCK
position, the limited slip differential in the rear axle still
provides torque biasing capability for moderate low
traction environments.
During the command to lock the axle, the indicator light
will flash until the axle is locked. After the lock command
has been successfully executed, the light will remain on
solid.
To lock the rear axle, place the vehicle in 4LO by
following the procedure in Four Wheel Drive Operation,
located in this section of the manual. Move the axle
locker switch position to REAR LOCK while traveling
less than 3 MPH (5 KM/H)
. The RR indicator light will
remain on when the rear axle is locked.
NOTE: Left to right wheel speed difference may be
necessary to allow the axle to fully lock. If the indicator
light is flashing after placing the switch in the REAR
LOCK or FRONT/REAR position, drive the vehicle in a
turn or on loose gravel to expedite the locking action.
WARNING!
Do not use the locked axle position for normal
driving. A locked front axle is intended for off-road
driving only. Locking the front axle during on-road
driving will reduce the steering ability. This could
cause an accident and you may be seriously injured.
To lock the front axle move the axle locker switch to
FRONT/REAR while traveling less than 3 MPH (5
KM/H)
. The indicator light will be solid when the front
axle is locked.
