Am looking at a 90 4runner w\ 180,000 miles on it. Most
everything is in good enough shape but I am not sure if the Auto
Locking Hubs \ 4WD system is working or not. If I shift into 4WD
while driving on a paved road the dash light does come on but I
do not feel or hear any changes. We don't have any snow around
here right now to check it out on. Is there a simple way to
verify that the system is functioning?? Thanks for any help.

While in 4wd, make a tight turn. If you're in 4wd, the front end will start
to bind up. Make sure you don't have manual hubs.


Good Luck

Put it into 4wd, jack it up, and try rotating the front tires by
hand. You'll see the driveshaft rotate.
