Delphi Suspension Ball Joint P/N:TC1653
Keep steering tight and suspension movement controlled with the Delphi ball joint TC5598, a direct-fit front lower ball joint for the 2003-2005 Lincoln Aviator. This pivot connects the front lower control arm to the steering knuckle, allowing the wheel to steer and the suspension to travel while supporting the load path through the corner. If a worn joint is behind your clunking, uneven tire wear, or loose steering, this Delphi unit replaces it.
Built on Delphi's OE expertise, this aftermarket steering part is tested to the extreme — withstanding temperatures below -40 degrees C and over 120 degrees C and 720 hours of salt spray — with extensive dimensional and material analysis for close OE-to-aftermarket compatibility. Ball joints wear as a pair on an axle; inspect both sides and replace as needed for balanced steering.
