It uses a press-in mounting design and a pre-greased, sealed construction with a plastic bearing type and rubber dust boot to support smooth suspension articulation. Delphi applies OE-based engineering and extensive dimensional and material checks to help maintain correct interface and fitment for the original suspension layout. This part cross-references Dorman Premium B9441PR for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Repair Symptoms\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFront-end clunking or popping over bumps\u003c\/li\u003e\n\u003cli\u003eExcessive play in the lower suspension joint\u003c\/li\u003e\n\u003cli\u003eUneven tire wear from worn steering and suspension geometry\u003c\/li\u003e\n\u003cli\u003eLoose or imprecise front suspension response\u003c\/li\u003e\n\u003cli\u003eVisible boot damage or joint contamination\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFits 1986-1990 Acura Legend, front lower. Confirm press-in service requirements before installation and verify the left-hand thread direction, tapered stud dimensions, and mounting style against the original part. Because this ball joint is pre-greased and not greaseable, no routine lubrication fitting is used. Replace worn related suspension components as needed to help preserve alignment and steering feel.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDelphi subjects its OE-style steering and suspension components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure testing. TC4312 is backed by Delphi’s OE-focused manufacturing standards for aftermarket suspension service.\u003c\/p\u003e","brand":"Delphi","offers":[{"title":"Default Title","offer_id":52435694911669,"sku":"BBMX-TC4312","price":21.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DE_TC4312_FRO.jpg?v=1777862182","url":"https:\/\/www.partcatalog.com\/products\/delphi-tc4312-suspension-ball-joint-front-lower","provider":"PartCatalog","version":"1.0","type":"link"}
