The nitrile sealing element is specified to create a tight barrier at the differential pinion area, helping reduce contamination from dirt and moisture while supporting leak resistance. This makes the WS1994 a practical service part for vehicles that see daily commuting, work use, or off-road exposure. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application. Compatible with 1987-1993 Mazda B2200 rear outer, 1987-1993 Mazda B2600 rear outer, 1981-1987 Isuzu Pickup rear outer, 1987 Isuzu Trooper rear outer to 06\/30\/1987, 1986-1987 Mazda B2000 rear outer, 1979-1984 Mazda B2000 rear outer, 1984-1986 Isuzu Trooper rear outer, and 1972-1982 Ford Courier rear outer. The WS1994 is also a fitment match for rear outer service on Mazda B2200, Mazda B2600, and Isuzu Pickup applications where the listed dimensions align.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGear oil seepage at the differential pinion seal area\u003c\/li\u003e\n\u003cli\u003eContamination from dust, water, and road debris\u003c\/li\u003e\n\u003cli\u003eSeal wear that can affect rear axle service life\u003c\/li\u003e\n\u003cli\u003eMaintenance needs on older Mazda, Isuzu, and Ford driveline assemblies\u003c\/li\u003e\n\u003cli\u003eNoise or driveline concerns related to compromised sealing surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the inside diameter, outside diameter, width, shaft diameter, and housing bore before installation. Inspect the sealing surface for scoring, corrosion, or debris, and clean the bore thoroughly so the nitrile seal seats evenly. Confirm the vehicle position as rear outer and match the application notes, including the 1987 Isuzu Trooper cutoff date of 06\/30\/1987. Use proper seal installation practices to avoid distortion during service.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eInMotion manufactures this seal with dimensional specifications intended to support consistent fitment and sealing performance in the listed applications.
