Different move Case Options in Four-Wheel excursion Vehicles

All four-wheel excursion vehicles come with a move case. The box, located just behind the transmission, takes the torque generated by the engine and distributes it to the excursion shafts. This part also synchronizes the rotations of the wheels and can contain low range gears so you can take the means off-road. There are several options used by four-wheel excursion vehicles.

excursion Types

There are two main choices in excursion types. Each has its benefits depending on the means use. One kind is the gear-pushed move case. This system uses sets of gears to excursion the front and back excursion shafts. This design works well with strong, heavy units. Commonly, they are in larger trucks. However, they are showing up more frequently in passenger cars.

Chain-pushed designs only excursion a single axle. Rarely, some vehicles use this design to excursion both shafts. These are quieter than a gear-pushed version. Compact trucks, Jeeps, SUVs, and complete-sized trucks use this kind of excursion. However, many serious off-road drivers change this kind of design to a gear pushed form. They prefer the additional strength provided by the unit and put up with the additional noise.

move Case Shift Types

As with excursion types, there are a few different shift types. One is the Electronic Shift on the Fly (ESOF). This shift kind comes with a dash-mounted selector that selects between all-wheel and two-wheel excursion. To include the selector for four-wheel excursion high, you must excursion at a lower speed. If you want to include the four-wheel excursion low, the means must be stopped, and the transmission put in neutral.

The other excursion kind is the Manual Shift on the Fly (MSOF). The MSOF has a selector lever located on the floor transmission hump. This shift kind sometimes has two sealed automatic front axle hubs with selectors of lock, unlock, or free. As with the ESOF, to include the high setting, your means must be moving at a low speed. The means, to shift into low gear transmission, must be in neutral with the means stopped.


When it comes to housing, like everything else, there are a associate of different choices. The first option is a married move case housing. This method that the part is bolted directly to the transmission. With this housing, you find it between the transmission output shaft and the rear of the main excursion shaft. In some situations, the case is part of the transmission and the two proportion the same housing.

The other kind of housing is a divorced/independent form. Unlike the married version, this one is not mounted directly on the transmission. Instead, it is located away from the transmission and connected by a driveshaft. This housing kind is found only in vehicles with a long wheelbase, such as a military or commercial means.

A move case can be a combination of any of these types. A chain-pushed form can be MSOF and contained in a married housing, for example. The design of the part will depend on the manufacturer.
