What is the difference between full time and part time 4 wheel drive on a jeep Cherokee?

Answer 1

Four Wheel Drive Modes Two-wheel drive (2Hi): In this position, the front axle spins freely while power is sent to the rear axle and wheels, which then drives the vehicle. Part-time four-wheel drive high-range (4 PART TIME): In this position, the centre differential mechanically locks the front and rear driveshafts together, which then rotate at the same speed for maximum traction (this position is designed for temporary use when extra traction is required; only use on slippery or loose surfaces). Full-time four-wheel drive high-range (4 FULL TIME): In this position, the centre differential splits the power, sending 48 percent to the front axle, and 52 percent to the rear. The transfer case may be left in this position on any road surface - including dry, paved roads.

Answer 2

full time can be engaged on any surface at any time, part time is more restricted you can't be engage cruising down the highway or it can be used on paved roads if its snowing or really slick but it can't be on just regular dry pavement, hope this helps

Answer 3

That is the type of 4wd you should only use part time, when off road or very icy conditions. Not for use on dry pavement.
