What is the construction and purpose of differentials?

Differentials are drivetrain components mounted on the drive axle or in the axle housing. They usually consist of a housing, final drive, spider gears, side gears, bearings, and seals. Their task is to distribute torque between the wheels of one axle and allow for a difference in rotational speed while turning.

What are differentials used for?

Differentials are used for smooth power transfer to the wheels while maintaining car stability in corners. Thanks to them, the inner and outer wheels of the drive axle can rotate at different speeds without jerking the drivetrain. Failure of this assembly can cause noise, overload the half-shafts, and impair vehicle handling.

What is the construction and function of differential bearings?

Differential bearing is a system of bearings supporting the pinion shaft and the differential carrier. It serves to maintain the proper position of gear elements, limit backlash, and ensure uniform gear operation. Its condition affects noise levels, gear durability, and the tightness of the entire assembly.

How to choose a differential for a specific car version?

When choosing, it is best to compare the OEM part number, interchangeable numbers, gear ratio, and vehicle placement. It is also worth checking the fuel type, body version, drive type, and compatibility with half-shafts and the driveshaft. If the car was available in several equipment variants, verification by VIN will also be helpful.

What symptoms may indicate differential wear?

Most commonly, these are whining or humming sounds that increase with speed, jerking when changing loads, and noticeable play in the drivetrain. Symptoms also include oil leaks from the housing and uneven operation during turns. Such signals should be compared with the condition of bearings, seals, and mounts.

What does the installation and maintenance of a differential look like?

Installation involves removing the driveshaft, disconnecting the half-shafts, replacing the assembly, and resetting all connections according to the manufacturer's documentation. After installation, check for leaks, mount condition, and the correct oil specified for the given design. In operation, regular checks for leaks, noise, and play appearing during driving are important.
