This video will discuss how 4WD systems work, using the Nissan Frontier Pro-4X as an example. The power is sent from the engine to a chain-style transfer case, which splits torque between the front and rear axle. The rear axle also has a locking differential.

    what exactly is traction control? is it different than "locking" my front wheels in 1st gen 98 tacoma?

    Wait, you said 2017 model? You can still buy that old Navara (as it's badged in Australia) over there? We got the new model in march 2015…

    If the car is on a lift, you will have three tires spinning in the air. The forth one wont spin.

    I would like you to do this test on a Ford, Dodge or GMC/Chevy because I tried the acceleration tests in 2WD and 4Hi in my F-150 and because on 4Hi it is 50/50 torque front/rear my acceleration seemed quicker.

    Minor nitpick. In the situation where three tires don't have traction, the front tire will not spin at the same speed as the rear tires. The front and rear output shafts will spin at the same speed, of course, but due to the open diff and stationary right wheel, the front left tire will spin at twice the speed of the rears (due to spider gears in diff).

    I have a 4wd vehicle which might not have as much traction as this one; alternately perhaps it applies torque very suddenly in first gear. In some cases I've used 4wd to prevent wheelspin on hard acceleration on pavement, although usually that was because of a bump or slippery spot. I have, if memory serves, caused wheelspin on pavement in 4lo however.

    Not a good test. It should be tested in sand, loose gravel, snow or ice.

  13. Post By Peter Konrad Konneker

    That seems highly complicated.

    So please tell us under what circumstances would we choose one function over the other?

    My 2012 Land Rover LR4 HSE Lux has a permanent 4WD system, but no 2H, 4H, and 4L. It used Land Rover's Terrain Response system. You should consider making a video explaining that system.

    Great video, always liked the styling of Nissan's Frontier, but I've heard a lot of bad about them.

    They still make the Frontier???

  18. Post By Bev

    In Australia we call that a Navara
