ZF 4657.298.110 HOUSING REAR SECTION for WG210 | OEM Genuine Part

Overview

The ZF 4657.298.110 HOUSING REAR SECTION is a critical structural component designed specifically for the WG210 series transmission. This OEM genuine part encloses the rear planetary gearset and output shaft assembly, providing essential alignment and protection for internal rotating elements. As the terminal housing section, it seals the transmission’s rear end while supporting the output flange. The SKU 4657.298.110 is precision-cast from high-strength aluminum alloy to withstand torsional loads and thermal expansion during heavy-duty operation. When replacing this housing, it is common to also inspect the TRANSMISSION HOUSING (4657101086) for cracks or wear, as both components share critical sealing interfaces.

Symptoms of Failure

• Rear main seal oil leakage: A worn 4657.298.110 housing often develops hairline cracks near the output shaft bore, causing transmission fluid to drip from the bellhousing area. This is a common long-tail search query for “ZF WG210 rear housing oil leak.”
• Output shaft play or vibration: Degraded bearing seats within the housing allow radial movement of the output shaft, leading to driveline shudder during acceleration or deceleration.
• Gear engagement noise: When the housing distorts from thermal stress, planetary gear alignment shifts, producing a distinct whining or grinding sound in reverse and lower forward gears.
• Contaminated transmission fluid: Cracks in the housing can allow debris ingress, while internal fractures may shed aluminum particles into the oil, detectable during routine filter inspections.

Technical Specifications

Compatibility

This housing rear section is engineered for the ZF WG210 series, but it also fits select variants in the WG180 and WG200 families due to shared rear housing architecture. Specifically, it is compatible with WG180-110, WG200-120, and WG210-130 models manufactured after 2010. Always verify the casting number on your existing housing before ordering. For complete assembly, pair this part with the HOUS.FRONT SECT (4657201176) and the HOUSING REAR PART (4657201179) to ensure proper sealing across all mating surfaces. Use SURFACE SEALING COMPOUND (0666790033) during installation to prevent fluid migration between housing sections.
