The differential is basically an equipment that splits car engine torque in two ways allowing every output to roll at a completely different speed. You can find the differential on all the modern trucks and cars available these days and also in the all-wheel-drive vehicles popularly called full-time four-wheel-drive vehicles. The all-wheel drive automobiles require a differential amid every set of the drive wheels and they also require one amid the back and the front wheels. This is because of the fact that front wheels generally travel a completely different distance via a turn in comparison to rear wheels.
Is the Differential present in All Vehicles?
One thing that you should note about the four-wheel drive vehicles is that the differential is present only in the full-time four-wheel drive vehicles and not in the part-time four-wheel drive vehicles. The part-time four-wheel drive vehicles are generally locked together in order to ensure that the rear and the front wheels turn at a similar average speed. It is only because of this reason that it is very difficult to turn the part-time four-wheel drive vehicles on concrete.
Locating the Front Differential
Having a look at the back axle of a truck which is found under the truck, you will get the sight of a very long thing that looks like a pipe running from one tire to another. You will find a very big round thing in the center and this is the rear differential. You will find the Front Differential amid the front wheels but the front differential is a bit off-center. If in any circumstances, the front or the rear differential of your car gets damaged or cracked, you need to fix it immediately. Go for replacements in place of getting completely new differentials because getting new differentials can turn out to be a costly affair.
Taking Care of the Front Differential?
The Front Differential is actually the front axle of vehicles and this helps in driving the front wheels. There are a number of steps that you need to carry out in taking good care of your vehicle’s differential and the steps have been enumerated below:
Preparing the Area
Preparing the area can turn out to be a very tidy or a very messy job depending on the differential design. There are some differentials featuring drain plug while there are others that require removing the protective cover. For both these varieties of differentials you will require a very wide and good quality catch pan. Try driving your vehicle for some time in order to get warm up the oil and then start with the procedure. What you are doing is here is all about changing the car oil. Keep in mind that old oil in the differential smells the foulest. Next, you need to remove fill-hole plug, get hold of drain plug or housing cover and unscrew it. Use a screwdriver for gently opening the cover so that the oil does not gush out. You should be very careful while carrying out these steps in order to avoid marring the differential housing surface. Allow the oil to drain completely and only then try removing the cover.
You need to just imagine that leftover oil is filled with different metal shadings. Take your time and wipe all the remaining oil from the gears, housing cover and the housing itself. You should ensure to wipe off every corner so that no metal shavings remain in the crannies and the nooks. The fill-hole plug tip should also be cleaned but avoid using harsh cleaners.
Fill the Differential to the Rim
Use highest quality oil within your budget for filling the differential to the rim. You will find the capacity and the weight listed in the owner’s manual. Generally, differentials possess the capacity of holding 3 quarts. However, it is very important to thoroughly read the owner’s manual because some differentials need a secondary abrasion-modifying additive. Fill the differential to the rim and when you find oil dripping out, the procedure is finished. Now you need to install back the plug and torque the plug to the spec.
