• Greaseable design with grease fitting included
• Dust boot included with chloroprene rubber construction
• Alloy steel SAE 5140 ball and carbon steel SAE 1040 housing
• Castle nut, cotter pin, nuts, washers, and mounting hardware included
• Standard replacement grade with tapered threaded stud
• OE-focused dimensional and material analysis for fit consistency

Product Details

Delphi TC1847 is engineered as a standard replacement suspension ball joint for the front lower position. Delphi applies OE-level testing and material analysis to help maintain proper compatibility between the replacement part and the original suspension geometry. The part is tested for extreme temperature exposure and salt-spray resistance, supporting durability in demanding road conditions. This part cross-references MOOG Chassis Products K6509 and Mevotech Supreme MK6509 for the same application.

Compatible With 1996-2000 Chevrolet K2500, front lower; 1996-2000 Chevrolet K3500, front lower; 1996-1999 Chevrolet K1500, front lower; 1997-1999 Chevrolet K1500 Suburban, front lower; 1996-1999 Chevrolet K2500 Suburban, front lower; 1999-2000 Cadillac Escalade, front lower; and matching GMC K1500, K2500, K2500 Suburban, K3500, and K1500 Suburban front lower applications listed in the fitment data.

Common Problems This Part Addresses

• Front suspension looseness or play at the lower ball joint
• Clunking or knocking from the front suspension over bumps
• Uneven tire wear caused by worn steering and suspension joints
• Steering wander or imprecise front-end response
• Boot damage that can allow contamination into the joint

Installation Notes and Tips

Verify the vehicle’s forged arm and press-fit diameter before installation, especially on K2500 and K2500 Suburban applications noted with the 47.89 mm press-fit specification. This is a press-in front lower ball joint, so proper removal and installation tools are recommended to avoid damage to the control arm. Confirm the tapered stud, thread size, and included hardware match the original setup before final assembly.

Quality Assurance

Delphi uses OE-focused engineering, dimensional checks, and material analysis to support fit and function. The part is also subjected to temperature extremes and extended salt-spray testing to evaluate durability in harsh environments.
