The stamped steel arm uses a painted black finish and includes the ball joint, bushings, dust boot, mounting hardware, and locking nut for a complete replacement assembly. Delphi applies OE dimensional and material analysis to help maintain proper fit and suspension alignment on the Tacoma platform. This part cross-references MOOG Chassis Products RK623414 and Mevotech Supreme CMS861297 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Repair Symptoms\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFront-end clunking or knocking over bumps\u003c\/li\u003e\n\u003cli\u003eUneven tire wear from worn suspension geometry\u003c\/li\u003e\n\u003cli\u003eLoose or wandering steering feel\u003c\/li\u003e\n\u003cli\u003eExcessive play from a worn ball joint or bushings\u003c\/li\u003e\n\u003cli\u003eVisible cracking, corrosion, or damage to the lower control arm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eInstall TC3986 on the front left lower position only. Because the ball joint is press-in and the arm is non-adjustable, proper removal and installation tools are important for a clean service job. After installation on a Toyota Tacoma, verify alignment and inspect adjacent suspension components for wear before returning the vehicle to service.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDelphi subjects its steering and suspension parts to extreme temperature and salt-spray testing, along with dimensional and material checks to support OE-level fit and durability. The TC3986 is built using Delphi’s OE-focused engineering approach for the Toyota Tacoma front left lower suspension position.\u003c\/p\u003e","brand":"Delphi","offers":[{"title":"Default Title","offer_id":52435692355765,"sku":"BBMX-TC3986","price":235.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DE_TC3986_FRO.jpg?v=1777861730","url":"https:\/\/www.partcatalog.com\/products\/delphi-tc3986-suspension-control-arm-and-ball-joint-assembly-front-left-lower","provider":"PartCatalog","version":"1.0","type":"link"}
