ZF 4699.372.116 STEERING GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4699.372.116 STEERING GEAR is a critical component within the final drive assembly of ZF WG-series transmissions. This OEM genuine part, identified by SKU 4699.372.116, precisely controls the directional output of torque from the differential to the axle shafts. It sits directly within the gear housing, meshing with the ring gear to convert rotational motion into the linear force required for steering. For optimal assembly integrity, this steering gear is often installed alongside the 4699100080: BASIC GEARBOX, which houses the primary gear set. Proper sealing is ensured by pairing it with the 0634309122: SHAFT SEAL and the 0634801038: SEALING RING to prevent lubricant loss.

Symptoms of Failure

• Erratic steering response and gear slipping: When the steering gear teeth wear down, you may experience intermittent loss of directional control or a “slipping” sensation during turns, especially under load.
• Hydraulic oil leaks near the steering housing: A worn steering gear often damages adjacent seals. Look for fluid pooling around the housing, which indicates the 0630000091: SHIM RING or shaft seal has been compromised.
• Excessive play or freewheel in the steering wheel: A noticeable dead zone before the wheels respond is a classic sign of internal gear backlash caused by a degraded steering gear.
• Grinding or whining noise during low-speed maneuvers: Metal-on-metal contact from a failing steering gear produces distinct audible feedback, often worsening as the transmission warms up.

Technical Specifications

Compatibility

This steering gear is engineered for the ZF WG100, WG130, and WG131 transmission series. It is also a direct replacement for units found in the WG180 and WG200 models when used in steering axle configurations. Always verify the spline count and shaft diameter against your existing part before installation. For precise shimming during rebuilds, consider the 0630000255: SHIM RING or the 0630000058: SHIM RING to adjust preload. Additional shim options include the 0630000059: SHIM RING and 0630000061: SHIM RING for fine tolerances. The assembly also requires the 0501341241: WHEEL STUD for hub mounting and the 0750117782: TAPERED ROLLER BEARING for smooth rotational support.
