Detailed Description

Delphi TC1624 is engineered as a standard replacement suspension ball joint for the front lower position. It is built with an alloy steel SAE 5140 ball and carbon steel SAE 1040 housing, along with a chloroprene rubber dust boot to help protect the joint in demanding undercar conditions. Delphi applies OE-level dimensional and material analysis to support proper fit and consistent suspension geometry on the Chevrolet Silverado 1500 and GMC Sierra 1500.

Delphi tests steering and suspension components under extreme temperature and corrosion conditions, including exposure below -40 degrees C, above 120 degrees C, and 720 hours of salt spray. This part cross-references MOOG Chassis Products K6539 and Mevotech Supreme MK6539 for the same application. Delphi TC1624 is a direct-fit choice for front lower ball joint replacement on 1999-2006 Chevrolet Silverado 1500 and 1999-2006 GMC Sierra 1500, plus 2007 Chevrolet Silverado 1500 Classic and 2007 GMC Sierra 1500 Classic, except high performance models.

What This Part Helps Address

• Front-end looseness or play from a worn lower ball joint
• Clunking or popping noises from the front suspension
• Uneven tire wear caused by suspension joint wear
• Steering wander or reduced directional stability
• Restoration of proper suspension articulation at the lower control arm

Installation Notes and Tips

Fits 1999-2006 Chevrolet Silverado 1500, front lower. Fits 1999-2006 GMC Sierra 1500, front lower. Fits 2007 Chevrolet Silverado 1500 Classic, front lower, except high performance.
