The seal helps maintain a tight barrier at the pinion area, reducing the chance that debris and moisture reach internal differential components while also helping retain lubricant. Compatible applications include rear fitments for Toyota 4Runner, Toyota Pickup, Toyota Supra, Nissan D21, Nissan 280ZX, Volvo 760, and other listed vehicles. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGear oil seepage at the differential pinion area.\u003c\/li\u003e\n\u003cli\u003eContamination from dirt and moisture entering the housing.\u003c\/li\u003e\n\u003cli\u003eWear caused by compromised sealing surfaces.\u003c\/li\u003e\n\u003cli\u003eLoss of lubricant that can affect differential operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify the housing bore, shaft diameter, and outside diameter before installation.
