The seal uses a nitrile sealing surface and is specified with a 4.179-inch outside diameter, 3.125-inch shaft diameter, and 0.290-inch width. Those dimensions make part number 31203 a direct-reference option when matching an OE-style wheel seal by size rather than by appearance alone. SKF has a long history of seal development, and this wheel seal reflects that focus on material selection and dimensional accuracy for demanding driveline service.\u003c\/p\u003e\u003cp\u003eThis part cross-references Chrysler (e.g., 47421, 3858316) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Seal Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGear oil leakage at the wheel-end seal area\u003c\/li\u003e\n\u003cli\u003eContamination entering the hub or axle assembly\u003c\/li\u003e\n\u003cli\u003ePremature wear caused by degraded sealing surfaces\u003c\/li\u003e\n\u003cli\u003eService issues from an incorrect seal diameter or width\u003c\/li\u003e\n\u003cli\u003eNoise or driveline concerns related to low lubricant retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the shaft diameter, outside diameter, and width before installation to confirm the seal matches the original specification. Inspect the sealing surface, hub bore, and axle surface for wear, scoring, or corrosion before pressing in the new seal. Clean the mating surfaces thoroughly and install the seal squarely to avoid distortion. For fitment-based searches, this part is commonly referenced for Honda Civic and Toyota Corolla wheel seal applications, but final selection should always follow the measured dimensions and vehicle service data.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eSKF manufactures seals to specific designs using premium materials and established quality standards.
