Genuine OEM Nissan Rear Differential Rear Pinion Bearing – R200 Differential – 38120-10V00
Restore smooth, reliable differential operation with the Genuine OEM Nissan Rear Differential Rear Pinion Bearing – 38120-10V00, a factory replacement bearing designed for compatible Nissan R200 rear differential assemblies.
This genuine Nissan bearing supports the rear section of the differential pinion shaft, helping maintain correct pinion positioning and smooth rotation within the differential housing.
The pinion shaft transfers rotational force from the driveshaft to the differential ring gear, making its supporting bearings essential to the correct operation of the final drive assembly.
Over time, pinion bearings can deteriorate through high mileage, insufficient lubrication, contaminated differential oil, excessive loading or incorrect differential adjustment.
Worn or damaged pinion bearings may contribute to differential whine, rumbling noises, vibration, excessive pinion movement and accelerated wear of the ring and pinion gears.
Replacing a worn bearing with a correctly specified genuine Nissan component during a professional differential rebuild helps restore the intended bearing support, operating characteristics and reliability of the assembly.
Ideal for R200 differential rebuilds, driveline restorations and maintenance on compatible Nissan Skyline, Silvia, 180SX, Stagea and other Nissan performance vehicles.
Important: This listing includes one (1) Genuine OEM Nissan Rear Differential Rear Pinion Bearing – 38120-10V00 only. This is the rear pinion bearing within the differential assembly, not the front pinion bearing.

What Does the Rear Pinion Bearing Do?
The differential pinion shaft transfers drive from the vehicle's driveshaft to the ring gear inside the differential.
The pinion is supported by bearings that allow it to rotate smoothly while maintaining the required position relative to the ring gear.
The rear pinion bearing works with the front pinion bearing and associated adjustment components to support the pinion shaft under operating loads.
Correct bearing condition, preload and gear adjustment are essential for reliable differential operation.
A worn bearing may allow unwanted movement or produce noise, potentially contributing to damage elsewhere in the differential assembly.
Rear vs Front Differential Pinion Bearings
Compatible Nissan R200 differential assemblies use separate bearings to support the pinion shaft.
- Rear Pinion Bearing: 38120-10V00 – This Listing
- Front Pinion Bearing: 38120-13201 / 38120-1320A – Sold Separately, Where Applicable
These bearings serve different positions within the differential assembly and are not interchangeable.
Rebuild Tip: When rebuilding the differential, inspect both pinion bearings and verify the correct part numbers for your particular final drive assembly.
Common Signs of a Worn Differential Pinion Bearing
- Whining or rumbling noises from the differential
- Noise that changes under acceleration or deceleration
- Vibration or roughness from the rear driveline
- Excessive pinion shaft movement
- Metallic debris in the differential oil
- Roughness when rotating the pinion during inspection
- Visible bearing surface damage or overheating
- Abnormal differential noise following incorrect setup or lubrication problems
Important: These symptoms may also be caused by worn ring and pinion gears, incorrect backlash, damaged side bearings, wheel bearings or other driveline components. A proper diagnosis is recommended before replacing individual differential parts.
Ideal for Nissan R200 Differential Rebuilds
The Nissan R200 differential has been used across a wide range of Nissan rear-wheel-drive and performance vehicle applications.
As these vehicles age, differential rebuilds are increasingly common during restorations, driveline upgrades and preventative maintenance.
Replacing worn internal bearings with correctly specified genuine Nissan components helps maintain the intended mechanical operation of the differential.
This bearing is suitable for:
- Professional R200 differential rebuilds
- Replacement of worn or damaged rear pinion bearings
- Skyline and Silvia driveline restorations
- Repairs following differential bearing noise or damage
- Inspection and overhaul of high-mileage differential assemblies
- Rebuilding compatible factory Nissan final drive units
- Restoring correct pinion support during ring and pinion servicing
Recommended Parts to Inspect During a Differential Rebuild
When replacing a differential pinion bearing, it is important to inspect the condition of the complete differential assembly rather than replacing the bearing in isolation.
Depending on the differential design and service requirements, related components may include:
- Front pinion bearing
- Differential carrier side bearings
- Pinion oil seal
- Pinion collapsible spacer or applicable preload-setting components
- Pinion nut and associated hardware
- Ring and pinion gear set
- Carrier bearing adjustment components
- Differential housing seals and gaskets
- Correct differential oil
Rebuild Tip: Always use the correct components and factory adjustment procedure for the specific differential assembly being rebuilt.
Installation & Differential Setup Information
Pinion bearing replacement is a precision differential repair requiring specialist tools and mechanical knowledge.
Correct installation may involve bearing race removal and installation, pinion bearing preload adjustment, backlash measurement and verification of the ring and pinion contact pattern.
Depending on the differential design, a new collapsible spacer or other preload-setting components may be required.
Incorrect bearing installation or differential adjustment can result in excessive noise, overheating, premature bearing wear or ring and pinion damage.
Professional Installation Strongly Recommended: This component should be installed by a qualified technician or differential specialist familiar with Nissan final drive assemblies.
Important: Replacing a pinion bearing alone does not guarantee the elimination of differential noise. Existing ring and pinion wear, incorrect gear adjustment or damage to other internal components must also be addressed.
