The nitrile construction is selected for sealing performance in driveline service, helping maintain a tight interface between the shaft and housing bore. This reduces the chance of lubricant loss and limits the entry of dirt, water, and other contaminants into the sealed area.\u003c\/p\u003e\u003cp\u003eFor technicians and owners servicing a Nissan 720 rear outer seal, WS1974 provides the dimensional consistency needed for proper fitment. The seal’s 1.969-inch inside diameter and shaft diameter, along with its 2.648-inch outside diameter and 2.638-inch housing bore, support accurate installation in the intended differential pinion sealing application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGear oil seepage at the rear outer seal area\u003c\/li\u003e\n\u003cli\u003eContamination from dust, moisture, and road debris\u003c\/li\u003e\n\u003cli\u003eWear caused by compromised sealing surfaces\u003c\/li\u003e\n\u003cli\u003eLoss of sealing integrity in driveline service\u003c\/li\u003e\n\u003cli\u003eService replacement needs on Nissan 720 rear outer applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm the rear outer position and SRW configuration before installation. Inspect the shaft and housing bore for wear, scoring, or corrosion, since seal performance depends on clean, smooth mating surfaces. Lubricate the sealing lip with the correct fluid during assembly and install the seal squarely to avoid distortion. Verify dimensions against the removed part when servicing a Nissan 720 to ensure WS1974 is the correct match.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eInMotion manufactures this seal with high-quality materials and precision-focused construction for driveline sealing service.
