This power steering pump shaft seal is made for applications where keeping power steering fluid contained and contaminants out is critical to steering performance. It is a direct-fit style service part for 1956-1957 Buick Century, 1956-1957 Buick Roadmaster, 1956-1957 Oldsmobile 88, 1957 Pontiac Bonneville, and 1956-1957 Pontiac Catalina. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower steering fluid leakage at the pump shaft\u003c\/li\u003e\n\u003cli\u003eContamination entering the steering pump area\u003c\/li\u003e\n\u003cli\u003eLoss of hydraulic pressure from worn sealing surfaces\u003c\/li\u003e\n\u003cli\u003eSteering pump service issues caused by aged or hardened seals\u003c\/li\u003e\n\u003cli\u003eFluid seepage that can leave residue around the pump housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm shaft diameter, outside diameter, and seal width before installation to match the pump specification. Inspect the pump shaft and sealing bore for wear, scoring, or corrosion, since surface damage can shorten seal life. Clean the sealing area thoroughly and install the seal squarely to avoid distortion. Verify the application against your vehicle and pump configuration before ordering, especially on classic Buick, Oldsmobile, and Pontiac steering systems.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eSKF manufactures seals to specific designs using premium materials and controlled production standards. The brand’s seal engineering heritage dates back to the first integrated shaft seal in 1928, and SKF seals have been used for decades in applications that require reliable fluid retention and contamination control.\u003c\/p\u003e","brand":"SKF","offers":[{"title":"Default Title","offer_id":52431261073589,"sku":"BCNB-9663","price":14.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/CR_9663_Fro.jpg?v=1777848511","url":"https:\/\/www.partcatalog.com\/products\/skf-9663-power-steering-pump-shaft-seal","provider":"PartCatalog","version":"1.0","type":"link"}
