NISSAN 39253-01J02 Drive Shaft Snap Ring

This genuine NISSAN (SKU: 39253-01J02) drive shaft snap ring is a critical retaining component in the vehicle's drivetrain system. Its primary function is the axial retention of the drive shaft joint or shaft assembly within splined connections, preventing unwanted disengagement during suspension travel.

Technical Features and Specifications:

• Part Type: Drive shaft snap ring / retaining ring
• Material Composition: Premium-grade hardened spring steel, designed to withstand continuous mechanical stress and vibration.
• Surface Finish: Corrosion-resistant phosphated or oiled coating for extended service life.
• Installation Recommendation: Snap rings operate under constant tension; therefore, replacement is mandatory whenever the assembly is disassembled (e.g., CV joint replacement, CV boot service) to guarantee secure retention.

Function and Symptoms of Failure:

The drive shaft snap ring ensures that the constant-velocity (CV) joint remains securely locked in place on the splined shaft. If the ring experiences fatigue, fractures, or deforms due to improper installation, the following issues may occur:

• Disengagement of the drive shaft, causing an immediate loss of motive power.
• Abnormal metallic clicking or knocking noises during cornering or load reversals.
• Transmission oil leakage at the drive shaft oil seal if the inner joint shifts out of position.

Choose genuine OEM Nissan components to ensure precise fitment, original factory tolerances, and maximum operational safety.
