You are watching: Part time 4 wheel drive jeep


I have actually a "98 grand Cherokee Laredo. Can someone please describe the differences between full and part time four wheel drive and when to use which?

Basically full time can be supplied anytime and part time must only be used where traction is in ~ a minimum (Ie. Offroad)

Highway speeds are fine in fulltime. The only time girlfriend really must be concerned around speed is once in 4-Lo

^thanksim quiet not understanding why us have component time. If traction suck i use full time, if the really sucks or ns stuck ns go 4 low. It makes sense top top jeeps without full time however i dont see why we have it. Or am i absent something?
On many jeeps the permanent mode method the auto is actually in 2wd until wheels begin to slip. Then it instantly engages 4wd. This is good for continual driving. However there are many times off road where girlfriend will want to have actually 4wd locked in instead of the automatically switching. If you"re top top a rock face or in a dirt hole the split 2nd that the takes to actuate have the right to be the difference between stuck or not, or perhaps a role over. To know the difference better, walk somewhere slippery with the vehicle in part time and hit the gas. You"ll an alert it will certainly grab best away. Perform the exact same thing in complete time and you"ll notification that it"ll slip for a second, climate you"ll feeling the 4wd kick in and also it"ll grab prefer the first test.

Wait! ns think the OP is talking around the 242 transfer case with permanent 4 HI, part time 4 hi , 4 low, N and 2WD.That is a different pet then the 249/247 full-time transfer case.On the 242 the part time 4 hello locks the former axle rotation speed to the behind axle rotation speed. This is poor to drive on pavement in that mode since the prior axle travels additional in a circle or turns then the rear. Which an easy means, If you revolve in component time 4 hi with traction such together pavement , the jeep will certainly bind and also tires will chirp and damage can occur. That is why the 242 has a full time 4 Hi place that attributes like an open differential therefore the front and also rear axles can rotate at different speeds. That does not us a Viscous coupling favor the 249/247 do. So once you are off roadway 4x4 on loose terrain/Mud, put it in component time 4 hello for preferably traction , or 4 short if you need the gear reduction on a challenging hill or rocksOn the Pavement through a small snow/ Ice use that open up transfer instance full time 4HI ,be reason you might hit dry patches on the road. Hell you can leave the in full time 4 hi without speed limitations if friend Like. But 2wd is a much better option if you have it.Just mental never component time 4 or 4 short if you space on Pavement. Save that added traction because that the trail.
