A Guide To Buy Differential Parts
Like several components of the vehicle, each has a specific task of keeping the vehicle moving. Apart from just moving the vehicle, moving it with efficiency is very important. This is where the differential plays its role. It plays an important role in how your vehicle makes turns, and it does that by allowing the wheels on the same axle to rotate at different speeds. This helps in minimizing wheel slip, and tire wear, and provides good traction for improved handling and maneuverability. This comprehensive Differential Parts Buying Guide will help you in understanding the working of the differential and its parts so you can make a wise choice while purchasing a replacement part for your vehicle.

1 What Is A Differential And Why Is It Important?
A differential is a system that receives the power from the engine, splits it, and transfers it to the wheels to spin at different speeds. When the vehicle moves around a corner or turns, the inner wheels travel a smaller distance and rotate at a slower speed compared to the outer wheels. The differential allows the wheels to rotate at different speeds and makes it easier for the vehicle to maneuver around a corner, which otherwise would have been difficult and would lead to wheel slip and excessive tire wear.
The differential splits the power between the two wheels with the help of gears. It consists of several parts like the ring and pinion gear, a planetary gear system attached to a carrier, differential bearings, and two half shafts to transmit power to each wheel. This assembly together makes up the differential and is housed in a differential cover that protects all the components from external elements.

2 What Is A Differential Ring And Pinion And How Does It Work?
The ring and pinion is a gear set located in the rear axle that transfers power from the driveshaft to the driveline. The ring gear has more teeth and is larger in diameter than the pinion gear. The ring gear is attached to the rear axle assembly and the pinion to the drive shaft. This arrangement of ring and pinion is kept at an angle of 90 degrees.
When the engine is running, the pinion gear receives power from the transmission via the driveshaft. As the pinion gear rotates, it rotates the ring gear too, consequently rotating the drive axles. The ring and pinion differential gear improves the drivetrain performance by multiplying the driveshaft torque and translating it at 90 degrees to drive the wheels.
What Are The Factors I Should Consider While Choosing A Differential Ring And Pinion?
The differential ring and pinion gears can significantly affect the performance of the vehicle, and it is important to know the right gear set for your vehicle. Some factors mentioned below can help in deciding the best differential ring and pinion for your vehicle.
1. Rear-End Type
Before choosing a differential ring and pinion gear, identify its rear end type. They can be conventional or banjo style. Conventional type rear ends are also called integrated rear ends, comprise a bolt-on style cover and C-slip axles. A banjo-style rear-end comes with bolt-in axles and a detachable rear section. To get the specific differential ring and pinion compatible with your vehicle, consult your vehicle’s manual or your mechanic to ensure the rear-end type on the vehicle.
2. Ring And Pinion Gear Ratio
The gear ratio of the differential ring and pinion gear defines the power output and the performance of the vehicle. If you are going to use your vehicle for high-performance applications like racing and off-roading, chasing an optimum gear ratio can significantly improve the performance of your vehicle. If you are into off-roading, a bigger ratio is recommended for more torque and short gear ratios for high-speed racing.

3 What Is Differential Bearing And How Does It Work?
The differential bearing is just like any other bearing used on the vehicle and is located on the differential casing to support the propeller shaft and the half shafts that drive the wheel. Bearings serve the purpose of reducing the friction between moving and non-moving parts and protecting the stationary components from the rotating ones. Bearings used in vehicles are of different types and they are designed to support axial and radial load. The force applied perpendicular to the rotation of the bearing is called a radial load, and the load acting parallel to the axis is called an axial load. Differential bearings support the propellor shaft, driveshafts, and the load of the vehicle.
The differential bearing just like any other bearing comprises an inner and outer ring. The outer ring remains in contact with the differential casing and the inner ring supports the shaft connecting to the differential gears. The bearing comprises spherical balls or rollers, depending on the type of bearing, and allows the axles to spin smoothly.
What Type Of Differential Bearing Should I Choose?
1. Ball Bearings
Ball bearings are the most common type of bearings used in vehicles. It comprises round metal balls between the bearing races, that offer a smooth rotation. These bearings are used in vehicles because they are capable of withstanding radial and axial load. The spherical balls in the ball bearings have less contact area, and they cannot withstand heavy impacts. Therefore, they are limited to specific applications and components
2. Roller Bearings
Roller bearings work on the same principle as that of ball bearings but comprise cylindrical rollers instead of spherical balls. These rollers are enclosed by inner and outer races and have a constant diameter across their length. This allows them to distribute the load across a wider contact point, making them capable of withstanding heavy loads. Roller bearings are ideal for heavy-duty applications and are used in differentials to support the pinion gears.
3. Tapered Roller Bearings
Tapered roller bearings are similar to straight roller bearings, but the rollers are tapered and placed at an angle. Tapered roller bearings have a cone-shaped assembly that helps in reducing friction at greater axial loads. Tapered roller bearings support both axial and radial load and maintain the correct interlocking of gears to transmit the driving force efficiently. Tapered roller bearings are more efficient than ball bearings and are a preferred choice for their use in differentials.

4 What Is A Differential Cover And What Is Its Function?
A differential cover is housing that protects the front or rear differential and its components. It creates a tight seal and prevents the lubricant from leaking and protects the ring and pinion gear from damage and impacts. It keeps the internal components free from dust, water, and debris. Differential covers are very useful on off-road vehicles because these vehicles are driven over rough terrains and any object such as rocks, branches, and boulders can damage the differential’s internal components.
What Are The Factors I Should Consider While Choosing A Differential Cover?
Aftermarket differential covers are offered with many features and if you are planning on purchasing one, keep in mind the following factors to get the best differential cover for your vehicle.
1. Material
The material of the differential cover plays an important role in heat dissipation and keeping the temperatures low. Aluminum differential covers are great for this purpose. Aluminum differential covers are lighter compared to cast-iron ones. Factory-fitted covers are made from stamped steel and are not potent enough to absorb heavy impacts. Therefore, if you need strength and a lightweight differential cover, aluminum ones are the best. Differentials covers are also provided with cooling fins to aid in cooling and reducing the oil temperature.
2. Fluid Capacity
Proper lubrication levels can increase the cooling efficiency and prevent the parts from damaging. Upgrading your differential cover with a larger one can increase the fluid capacity of the differential, aid in better cooling, and lower operating temperatures. Consult your vehicle’s manual for the capacity of differential on your vehicle to ensure you choose the right part or you can always go for larger aftermarket differential covers.
3. Ease Of Maintenance
Replacing your differential cover with a more user-friendly one can make your work so much easier. Some differential covers are equipped with a drain plug at the bottom for an easy oil change. This eliminates the need to dismantle the cover and install a new gasket every time you perform an oil change. Differential covers are also equipped with small glass windows and oil dipsticks for quick oil inspection. Look for differential covers with these features for ease of maintenance.

5 What Are The Symptoms That My Differential Parts Are Damaged?
A. Rumbling Or Whirring Noise
If the vehicle makes a rumbling noise while driving, it’s due to worn-out carrier bearings, worn-out pinion bearings, etc. If the sound is audible over 30 kmph and changes while taking turns, it’s because of bad carrier bearings. Worn-out pinion bearings make whirring noises at various speeds.
B. Loud Clicking Or Clunking Sound
If your car frequently makes loud clunking sounds when in motion, the pinion-gear tooth might be broken. The sound often occurs repeatedly every few feet while driving.
C. Grinding Noises While Cornering
If your vehicle makes grinding or clunking noises while cornering, the differential might be low on lubrication. Like the engine and transmission, your vehicle’s differential needs lubrication to function effectively. Gear oil is used in differential and low gear oil or a leaking differential cover gasket can lead to low oil levels and noises.
