Whether you have a front-wheel, rear-wheel, or all-wheel drive vehicle, you need a reliable differential to keep smooth turns possible. Whenever your car turns, the left and right wheels do not spin at the same rate. The inner wheel has to travel only a short distance, while the outer wheel has to travel a longer distance. If the wheels spin at the same rate, the tires of the outer wheels would skid.The differential is mounted on the driven axle, between the left and right wheels. It receives power from the driveshaft and then passes this power to the wheels. So, the part drives the wheels and enables them to spin at a different rate. The said assembly is made up of gears that mesh against each other. As long as the gears are in proper order, you can expect the differential to remain reliable. So how do you maintain the gears' good condition? Well, just see to it that they're properly lubricated. Ensure that the seals are in good shape, not damaged and not leaking lubricant. Do regular inspection to monitor the seals' condition.In case you find the seals damaged, get replacements immediately. And if you need a new differential, that's not a problem as well.
