Differential carrier cases

Satellite case spare parts for differential carrier

In this specialist catalogue we offer a wide selection of satellite cases, essential components for the correct operation of the transmission system in heavy-duty vehicles. These parts have the critical function of housing and supporting the internal gears that allow the difference in rotation between the wheels, ensuring efficient traction and stability while driving.

Our range is aimed at professional mechanics and transport companies who require high-precision spare parts for axle and drive-axle repairs. By purchasing online at Enrique Requena, you will be able to find the exact reference required for corrective maintenance, ensuring the compatibility and durability demanded by industrial vehicles in their day-to-day operations.

Key points for choosing the right spare part

• Original reference (OE): Always check the reference number engraved on the old part or in the manufacturer’s parts breakdown.
• Axle model: Make sure the case is compatible with the type of drive axle fitted to the vehicle, as it may vary even within the same truck model.
• Dimensions and splines: Check the number of splines and the diameters of the housings for the side gears and pinion gears.
• Internal configuration: Confirm whether you need a case for a standard differential or for locking systems, as the structure differs.

Frequently asked questions

What function does the satellite case perform within the differential carrier?

This housing acts as a structural support for the pinion gears and side gears. Its design allows torque to be transmitted from the ring gear to the axle shafts, enabling the wheels to rotate at different speeds, which is essential when cornering to prevent tyre scrub.

How can I identify the correct reference if I don’t have the part removed?

The most advisable option is to consult the vehicle’s technical documentation or use the Vehicle Identification Number (VIN) to check the drive axle parts breakdown. This will ensure full compatibility, as heavy-duty vehicles can be fitted with different differential carriers depending on their load configuration.

What are the symptoms of a damaged satellite case?

The most common signs include metallic noises or knocking coming from the rear axle when turning, excessive vibrations while driving, or the presence of metal shavings in the differential oil during preventive maintenance.

Is the case supplied empty or with the internal gears?

As a general rule, the reference “satellite case” refers to the machined empty housing. However, there are repair kits that may include internal components. We recommend reading the technical description of each product carefully to confirm the exact contents of the supply.
