Differentials - Differentials

Have you ever wondered what makes your car take corners smoothly and handle bumps in the road? It's all thanks to the differential gear —a key component of your car's drivetrain . Without this differential gear, Traveling would be significantly less comfortable and safer. A functioning differential ensures that each wheel rotates at the appropriate speed, adapted to road conditions and the driver's maneuvers. A malfunctioning or damaged differential can lead to numerous problems, from difficulty in steering the vehicle to serious failures of other drivetrain components. Symptoms of a faulty differential gear can include noise coming from the axle area, difficulty turning, and uneven tire wear. Therefore, it's important to regularly inspect your vehicle and ensure the condition of all its components. Our automotive parts store offers a wide selection of high-quality used differentials, which are not only durable but also available at attractive prices. You can easily order them online and add your chosen differential gear to your cart. Maintaining your differential gear is an investment in the comfort and safety of every journey, as well as the longevity of your vehicle's other components. Regular maintenance ensures a smooth ride regardless of road conditions or the type of equipment used. A car differential is a differential mechanism whose main function is to distribute torque between the drive wheels, allowing them to rotate at different speeds in curves. In passenger cars , open differentials, LSDs (Limited Slip Differentials), and electronic E-Diffs are most commonly used. For example, the differential in the BMW X3 E83 ensures precise torque transfer to the rear wheels, which improves traction on slippery surfaces. In practice, a typical BMW E46 318i rear differential has a gear ratio of 3.91:1 and weighs approximately 35 kg, allowing it to effectively work with the driveshaft and driveshafts. VIN-specific differential compatibility ensures full interchangeability and compatibility with the rest of the drivetrain. This reduces installation costs and minimizes the risk of vehicle malfunctions.

Thanks to OEM numbers, you can precisely match the differential to your specific car model and year.

The differential assembly procedure includes

1. Lifting the vehicle and removing the drive shaft.
2. Unscrewing and removing the old differential.
3. Installing the new differential while maintaining the manufacturer's tightening torques.
4. Differential oil change (standard 75W-90 API GL-5, 1.5–2.0 l ).
5. Drive test to check correct operation.

FAQ – frequently asked questions about car differentials

Question	Answer
What is the main purpose of the differential?	A differential is a differential mechanism that allows the drive wheels to rotate at different speeds, especially when cornering.
How does a rear differential work?	The rear differential transfers torque from the drive shaft to the rear wheels, allowing for variable speed control in corners and improving traction.
What does the differential OEM number mean?	The OEM (Original Equipment Manufacturer) number is a unique manufacturer code that identifies a specific vehicle model and year.
How to choose a differential for a BMW E46 318i?	It is best to choose a differential compatible with your vehicle's OEM number and VIN.
What are the benefits of differential LSD?	The LSD differential increases traction on surfaces with varying friction coefficients, reduces wheel slippage and improves cornering stability.
How much oil does a BMW differential require?	A standard BMW differential requires approximately 1.5–2.0 liters of 75W-90 API GL-5 oil, changed every 60,000–80,000 km.
Does the differential affect driving comfort?	Yes, a properly selected and efficient differential ensures a smooth ride, stability in corners and reduces vibrations and noise in the drive system.

Car differentials from Global Parts

A car's differential has a significant impact on fuel economy and tire wear, as proper torque distribution minimizes wheel slippage and excessive friction. By comparison, an open differential can increase tire wear with aggressive driving, while an LSD, or electronically controlled differential, improves stability during cornering and acceleration. By maintaining a functioning differential gear in your car, you're investing not only in driving comfort and safety, but also in the longevity of your vehicle. With genuine differentials from Global Parts, you can enjoy a smooth ride, even on challenging surfaces, and the peace of mind that every journey will be hassle-free.
