Overview
The ZF 4657.104.410 DIFFERENTIAL is a critical torque-distributing assembly engineered specifically for the WG 190 and WG 210 series transmissions. This OEM genuine part, identified by SKU 4657.104.410, sits at the heart of the final drive unit, managing rotational speed differences between the left and right drive wheels while transferring engine power to the axles. Designed to withstand high-load industrial applications, this differential works in concert with the TRANSMISSION HOUSING to ensure precise gear alignment and long-term durability under continuous operation.
Symptoms of Failure
- Whining or grinding noise during turns: When the differential gears wear, you will hear a distinct metallic whine or grinding sound when cornering, often searched as “ZF differential noise during turns.”
- Oil seepage around the axle seals: Worn differential bearings or housing cracks cause gear oil to leak past seals, leading to low lubricant levels and potential gear damage.
- Vibration under load: Excessive play in the differential spider gears creates driveline shudder, especially noticeable when accelerating from a stop or climbing grades.
- Uneven tire wear or wheel hop: A failing differential fails to distribute torque evenly, causing one wheel to spin faster than the other, resulting in premature tire scalloping and traction loss.

Compatibility
This differential is a direct fit for the ZF WG 190 and WG 210 transmission series. It is also compatible with earlier WG 180 and WG 200 variants when used with the appropriate HOUS.FRONT SECT and HOUSING REAR PART. For WG 210 applications, ensure the HOUSING REAR SECTION is properly aligned to avoid preload issues. Always verify your transmission model number before ordering.

Frequently Asked Questions
Q: Can I install this differential without replacing the housing sections?
A: Yes, the 4657.104.410 differential can be installed independently, but we strongly recommend inspecting the HOUS.FRONT SECT and HOUSING REAR PART for wear or cracks, as damaged housings will quickly ruin a new differential.
Q: What is the typical service life of this differential in a WG 210 transmission?
A: With proper lubrication and load conditions, the OEM genuine differential typically lasts 8,000–12,000 operating hours. Early failure often results from contaminated oil bypassing the SCREEN SHEET filters.
Q: Does this part include the fixing plate and cap screws?
A: No, the differential is supplied as a bare assembly. You will need to order the FIXING PLATE and CAP SCREW separately to complete the installation.
