0BH DQ500 Differential Side Gear Axle Gear

0BH DQ500 Differential Side Gear

0BH DQ500 Differential Side Gear is an internal transmission hard part designed for professional repair and rebuilding of the 0BH DQ500 7-speed dual-clutch transmission differential system. The side gear is installed inside the differential assembly and works together with the differential spider gears and axle drive components to transfer torque from the gearbox to the drive shafts.

The 0BH belongs to the DQ500 DSG transmission family. Professional transmission catalogs identify 0BH and 0BT as DQ500 7-speed dual-clutch transmissions and list dedicated differential gear and axle-drive components for this gearbox family.

This product is suitable for DSG transmission repair workshops, gearbox rebuilders, differential repair specialists, automotive spare parts wholesalers and transmission parts distributors.

0BH DQ500 Differential Side Gear Product Information

Basic product information:

Transmission: 0BH / DQ500
Product Type: Differential Side Gear
Alternative Name: Axle Gear / Differential Axle Gear
Part Category: Transmission Hard Part
Installation Area: Differential Assembly
Application: DSG Differential Repair and Rebuilding

The differential side gear should not be confused with the complete differential assembly or the smaller differential spider gears.

Professional DQ500 parts suppliers distinguish between complete differential gear sets, spider gears and axle-drive components, which confirms that several individual hard parts are used within the DQ500 differential system.

Because several DQ500 differential versions exist, customers should compare the original component carefully before ordering.

Function of the DQ500 Differential Side Gear

The differential side gear plays an important role in transmitting torque from the differential carrier to the axle shafts.

When power reaches the differential, the differential gear system allows torque to be distributed to the drive wheels while permitting differences in wheel speed during cornering.

The side gears are connected to the axle-drive system and work together with the differential spider gears inside the differential assembly.

During straight-line driving, the differential components rotate together to transfer torque. During cornering, the internal differential gears allow the left and right drive wheels to rotate at different speeds.

Because the side gear carries drivetrain load, its tooth surfaces, spline connection and supporting surfaces need to remain in good condition.

DQ500 Differential Hard Part Repair

The 0BH DQ500 Differential Side Gear is mainly used during professional gearbox rebuilding or differential repair.

Technicians may inspect the differential when a transmission has mechanical damage, abnormal drivetrain noise or visible wear inside the differential assembly.

Inspection may include checking:

• Gear tooth condition
• Internal spline condition
• Contact surfaces
• Differential spider gears
• Bearings and supporting surfaces
• Axle-shaft engagement
• Metal contamination inside the gearbox

A damaged side gear can affect torque transfer and may also damage other differential components if the transmission continues operating.

However, abnormal drivetrain noise does not automatically mean that the differential side gear is defective. Bearings, axle shafts, final-drive gears and other transmission components can produce similar symptoms.

Professional diagnosis and gearbox disassembly are recommended before replacing hard parts.

Difference Between Side Gear and Spider Gear

The terms side gear and spider gear are sometimes used incorrectly in transmission parts listings, so identifying the actual component is important.

A differential side gear connects to the axle-drive side of the differential.

A differential spider gear is the smaller gear that operates between the side gears and allows rotational-speed differences between the two output sides.

Professional DQ500 catalogs separately list differential spider gear repair kits and differential gear assemblies, showing that these are different components within the same differential system.

For this product page, the component is identified as a Differential Side Gear / Axle Gear.

Different 0BH DQ500 Differential Versions

DQ500 differential components can vary according to transmission and drivetrain configuration.

Specialist catalogs list different 0BH / 0DL DQ500 differential gear sets and note that several executions exist and must be checked carefully before installation. Some complete differential gear sets are identified with different final-drive tooth counts, demonstrating that not every DQ500 differential configuration is identical.

Individual side gears can also differ according to installation position. One specialist supplier specifically distinguishes left and right DQ500 differential side-gear applications.

For this reason, customers should not order an internal differential gear only according to the general “DQ500” name.

Check Left and Right Side Before Ordering

Before purchasing the 0BH DQ500 Differential Side Gear, please compare the original component carefully.

Important identification points include the gear structure, spline design, overall dimensions, installation side and transmission version.

If your original part is available, we recommend providing clear photos from several angles.

If any identification number is visible on the original component, send that information together with the inquiry.

For differential hard parts, accurate physical matching is especially important because a similar-looking gear may not have the same internal spline, dimensions or installation position.

For Transmission Rebuilders and Wholesalers

The 0BH DQ500 differential side gear is suitable for professional customers including DSG transmission workshops, gearbox rebuilders, differential repair specialists, automotive parts wholesalers and international transmission parts distributors.

Hard transmission parts are normally required when the gearbox has already been disassembled for mechanical repair.

Customers working with DQ500 transmissions may also require differential bearings, axle seals, oil pans, solenoids, clutch components, transmission filters and other repair parts.

KS supplies automatic transmission mechanical, hydraulic and electronic components for professional customers worldwide.
