Lincoln Navigator (2000) four-wheel driving [4/20] Wd and awd systems

drive over terrain and road

conditions that a conventional

two-wheel drive vehicle can’t.

Power is supplied to all four

wheels through a transfer case. On

4WD vehicles the transfer case

allows you to select 4WD when

necessary. Information on transfer

case operation, shifting procedures

and maintenance can be found in

your “Owner’s Guide.” You should

become thoroughly familiar with

this information before you operate

your vehicle.

Normal characteristics

• On some 4WD models, the initial

shift from two-wheel drive to

4x4 while the vehicle is moving

can cause some momentary

clunk and ratcheting sounds.

This is the front drivetrain

coming up to speed and the

automatic locking hubs engaging

and is not cause for concern.

• On some 4WD models, if the

vehicle is stopped while in 4WD

and the vehicle direction is

reversed from the previous

direction, the automatic locking

hubs will momentarily disengage

and re-engage. The automatic

locking hubs may click as they

automatically engage in the new

direction.
