What do differentials and parts consist of?

Differentials and parts are a set of drivetrain components mounted on the drive axle or in an AWD system. A typical set includes a housing, ring gear, pinion shaft, spider gears, side gears, bearings, and seals. Depending on the car's design, flanges, a speed sensor, and mounting elements are also included. Compatibility is primarily determined by the OEM number, gear ratio, and housing type.

What are differentials and parts used for?

Differentials are used to distribute torque to wheels on the same axle while maintaining a difference in their speed during a turn. This allows the drivetrain to operate smoothly, and tires and half-shafts are not excessively stressed in corners. A functional differential also affects traction, stability, and drivetrain performance. In AWD cars, it additionally cooperates with elements distributing power between axles.

What is the construction and function of differential bearings?

Differential bearings are rolling elements supporting the pinion shaft and the differential carrier. Their task is to maintain the alignment of the gear operation, reduce friction, and transfer loads generated during acceleration and engine braking. Worn bearings can cause whining, play, and an incorrect tooth contact pattern. When selecting, check the seat dimensions, bearing type, and compatibility with the given housing.

How to choose a differential for a specific car version?

It is safest to compare the OEM number, gear ratio designation, drive type, and body/engine version. It is also worth checking the flange diameter, shaft mounting method, presence of a sensor, and housing type. For 4x4 vehicles, compatibility with other drivetrain elements is also important.

What symptoms may indicate wear of the differential or its parts?

The most common symptoms are whining that increases with speed, vibrations during acceleration, clunking when changing loads, and oil leaks around the seals. In practice, it is also worth paying attention to excessive play on the flanges and uneven drivetrain operation in corners. Such signals do not always mean the entire unit is damaged, but they require verification of bearings, gears, and mounts.

How to take care of differentials after installation?

The basis is checking the level and quality of gear oil and regularly checking the housing for leaks. After installation, it is worth observing whether there is any noise, play, or weeping at the seals. It is also good practice to verify cooperating elements such as half-shafts, the drive shaft, and mounts so that the entire system operates without excessive loads.
