Wheels of car spin at different speeds while turning. Inside wheel always travel shorter distance as compare to outside wheels. Wheels traveling shorter distances always travel at lower speed. Similarly, front wheels and rear wheels travel at different distance.

In case of non-driven wheels on car, no connection exists between the front wheel on a rear-wheel drive car and rear-wheel on front wheel drive car. Thus, spinning is independent. On the other hand, driven wheels are always linked. This makes turning of both the wheels by transmission and single engine. A car without differential case requires locking of the wheels together. Thus, they will spin at same speed. This leads to tough turning and facing lot of problem.

Differential case is one such device that distributes the torque of engine in two ways. It allows spinning of the car wheels at different speed to make easy turns. This differential case is placed between the two wheels. A half-shaft is used for joining it to each wheel. This half shaft is rotated with the help of bevel gear.

If you have four-wheel driven car, there will be a different differential case for each wheel pair. In order to facilitate turning, several vehicle incorporates differential within the front and rear wheels. On the other hand, part-time 4-WD systems have no differential case between the front and rear wheels. These vehicles are fasten together that would result in the turning of front and rear wheels at same average speed.

On the splined end of each axle, a groove or splined axle side gear is placed. Little gears that are mounted on shaft are connected to differential case. This little gear drives the side gear. As differential case are supporting them, the side gear turn into the case. Differential case revolves around axle gear. Ring gear turns differential case and pinion shaft, but axle side gear will remain constant.

If your vehicle is creating problems while turning, you must replace the old differential case with a new one. After replacement, you will experience smooth ride and performance oriented engine. Instead of buying a brand new part, opt for a used differential case. They are available at pocket friendly prices.

There are several online catalogs that offer varied range of differential case. Just log on to the site and select according to the requirement. If you have any query regarding the product, you may call the customer care representative.
