3 20's in one hour, so 3 times 2/15 = 6/15 mile in one hour.
6/15 is reduced to 2/5 mile, which is equal to 0.4 mile, (4 tenths of a mile).

4WD Kicks Out While Driving


Have your transmission and transfer case checked, this could be the only parts broken on the basis of what you have told us. when you said you heard gears grinding, it is better to replace them.

In your case, I would presume that you were driving on a paved road, Engaging your 4WD on a paved road and doing 80-100km would really damage your 4WD system. wetness of a paved road is not enough to justify the use of your 4WD because there is enough traction on both front and rear tires that could cause your gears to resist each other.

It would be a different case if you drive at 80-100km on a dirt road or off road, i will assure you nothing wrong will happen.

You may still engage your 4WD on a wet paved road but do only a 60 or below.
