how do u control a part time 4 by 4 jeep grand cherokee?

Answer 1

The good news is that Jeep's part-time 4x4 is a shift-on-the-fly transfer case. Therefore engage 4x4hi as needed and disengage when on dry surfaces. You can keep it in 4x4 while driving in the snow, even over dry patches if you don't turn. You may wish to shift in/out of 4X4hi often during a trip through the snow.
I engage PT 4X4 when pulling the boat off the ramp, but disengage before making any turns.
There is no speed limit to shift in/out of PT 4X4hi -'Use at any legal speed'. I've tried it at 70 with no issues (yes, that was too fast for the conditions)

In Part-Time 4x4: the front and rear drive-shafts rotate at the same speed -always. Your transfer case, the unit that ties the front and rear together, is not differentiated. In a turn the front wheels need to turn at different speed than the rear wheels and would quickly wear-out the gears in your transfer case if you did this on dry pavement. Your transfer case is very strong and a few mistakes won't significantly damage anything.

Part-Time 4x4 Low is a different animal. I've found it best to be in 4x4Hi, stop, turn off engine, shift into 4x4Lo, restart and drive away -again only on slippery surfaces. Every other method tends to grind gears a bit.

The "Part Time" setting is designed to be used part of the time, while "Full Time" 4WD can be left engaged all the time; the latter will apply power to the front wheels as needed (i.e., rear wheel slippage). Part Time 4WD is not intended for use on hard dry surfaces. Check your owner's manual for shifting into 4WD Low; other than shutting off the engine, you can engage/disengage 4-Low at speeds less than 5 MPH and the transmission in neutral. You will need to pull the lever quickly (do not linger and allow gears to grind) into 4-Low. This setting is used for very slippery surfaces and rock crawling.... yes, your Jeep will crawl over some pretty substantial obstacles and through some deep mud if done properly (and the Jeep is properly equipped).

By the way, some of the newest Jeeps have a fully automatic 4WD system known as QuadraDrive II; this system automatically applies and disengages the front wheel(s) as the rears begin to slip. This is a truly phenomenal system - with mine, I have stopped in a steep hill covered with several inches of snow and ice, then continued further up the hill without even spinning a wheel.

Answer 3

Drive carefully, and for god sakes slow down. Just because it says 4X4 doesn't mean you can drive as fast as you want. Get some good all weather tires for better traction. Drive safely, allow extra room between the car in front of you and your vehicle.

Answer 4

...? don't understand what you mean by control it,doesn't make sense to me,it drives good in 2 wheel drive,good luck.

Answer 5

be alert and keeping both hands on the wheel
