The seal construction combines metal support, a spring element, and an auxiliary lip with nitrile sealing material to help maintain a consistent seal under operating conditions. Dimensions are tightly specified, including a 3.249-inch bore diameter, 3.254-inch outside diameter, and 1.875-inch width, which makes application matching important. This part number, SS2954, is listed for rear fitments on Cadillac Calais, Cadillac Commercial Chassis, Cadillac DeVille, Cadillac Fleetwood, Ford F-100, Ford F-250, and Ford P-350 applications shown in the fitment data.\u003c\/p\u003e\u003cp\u003eThis part cross-references Gates 18922 and National 451078 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStopping gear oil leakage at the differential pinion area\u003c\/li\u003e\n\u003cli\u003eKeeping dirt, dust, and moisture away from bearing components\u003c\/li\u003e\n\u003cli\u003eMaintaining lubricant retention over bearing service life\u003c\/li\u003e\n\u003cli\u003eReplacing a worn or hardened rear axle seal\u003c\/li\u003e\n\u003cli\u003eRestoring proper sealing in rear driveline service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the seal dimensions and rear application before installation. Clean the sealing surface and inspect the mating area for wear, scoring, or contamination that could affect sealing performance. Confirm the vehicle-specific application against the fitment data for Cadillac and Ford models before service. The SS2954 part number should be matched carefully to the axle and position listed for the vehicle.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eFAG states that its seals are built to meet vehicle manufacturer specifications and are developed with suppliers to meet FAG quality standards.
