4WD HIGHLANDER

Recommended Posts


Highlanders 4WD system is a full-time all wheel drive system and is always in use. It incorporates a center diff. with a built in viscous coupler, in which, limits slippage when the computer senses the tires slipping or losing traction. There is no levers to pull nor buttons to push. In actuality, it should be called all-wheel drive and not 4-wheel drive. So your dealer did not really deceive you, it really is automagic.

Here's another explanation:

"Full time four wheel drive" sounds more rugged than "all wheel drive" so

the former is often used to describe the system in SUV's. When driving all

4 wheels on dry pavement, a center differential is used to split the power

between the front and rear axles intead of a transfer case. A center

differential can vary the amount of power transmitted to the front and rear

axles, while a transfer case splits the power evenly. The transfer case's

even power split can cause premature tire wear and drivetrain binding on dry

pavement so it is not practical in permanent 4WD applications but they tend

to be more ruggedly built than center differentials. There are many

variations of the AWD theme, like center differentials that lock or have

viscous couplings, but they all allow variation between the front and rear

axles.
