4×4 Transfer Cases Explained. by Red Dot Engineering | Jan 25, 2022 | Red Dot News. 4×4 transfer cases are a part of your differential assembly that allows your truck to go into four-wheel drive while driving on paved roads. It also disengages it when needed. There are many variations in terms of design and functionality, but they all have Haldex is a part-time all-wheel-drive (AWD) system that automatically powers all four wheels only when necessary. It's mostly used on vehicles that operate primarily in front-wheel-drive (FWD) mode. Less frequently, it's employed on rear-wheel-drive vehicles to send power to the front wheels. The name is derived from the Swedish Haldex Traction Rear-wheel drive: Rear-wheel drive pushes the vehicle forward, and it’s helpful to have in more rugged conditions where your vehicle may take some wear and tear. All-wheel drive: All-wheel drive powers all four wheels at the same time, but these systems come in two types: full-time and part-time. Full-time powers all four wheels, while part The term quattro is Italian for “four,” which is appropriate given its association with Audi’s all-wheel drive system. Today, the Audi Quattro AWD system includes mechanical and electronic activation as well as intelligent software and sensors monitoring steering angle, traction, stability control, movement of the wheels, and yaw angle. RAV4 IV (2013-) (Proactive automatic all wheel drive.I has three modes: auto, lock and sport. When turning RAV4 into and through a corner, power is sent to the rear wheels to help enhance cornering performance, detecting steering angle and lack of yaw rate in Sport Mode (and detecting lack of yaw rate in Normal and Eco Mode).Dynamic Torque Control has three different drive modes: Auto, Lock XS (04/08)- Only come with a switchable (Auto AWD /4lo) 'Torque on Demand' automatic all wheel drive system; Allowing the driver to select between: Auto AWD - usually rear wheel drive it automatically directs power to the front wheels for improved traction, and 4WD-Lo for low-range gear transmission, (This TOC awd was also an optional extra for mixed snow and pavement, personally I would recommend 2hi with traction control. 4 wheel drive in a JT has no computer monitoring traction control at every wheel like an All Wheel Drive. It is purely mechanical. Its a different monster in the snow. Go to a nice big parking lot and practice. The difference between all-wheel drive, front-wheel drive and four-wheel drive seems more confusing than it actually is. Most modern cars are front-wheel drive, putting power to the wheels that are also steering the car. The same reasoning is applied to all-wheel-drive-equipped vehicles where power is distributed to all four wheels. If you have the ability to go faster, then you probably can move back into 4-high without an issue. To disengage your four-wheel-drive system, slow your Jeep down to a crawl and shift from drive into neutral. Then, while still rolling forward, push the transfer case shift lever up into 4-high. Once that is accomplished, put the Jeep back into Thanks for Watching!Follow us on Facebook ZVaBF.
