OE-Style Construction
Delphi applies OE engineering standards to its aftermarket steering and suspension portfolio, and TC2048 reflects that approach with careful dimensional and material analysis for fit and function. The ball joint uses alloy steel and carbon steel construction, a protective dust boot, and a bolt-in mounting layout to support consistent front-end service on the Dodge D50. This part cross-references MOOG Chassis Products K9044 for the same application.
Common Replacement Reasons
- Front suspension looseness or play
- Clunking or knocking from the front upper suspension area
- Uneven tire wear related to worn ball joint geometry
- Steering wander or reduced front-end response
- Visible boot wear, corrosion, or joint deterioration
Installation Notes
Fits 1979-1980 Dodge D50, front upper. Verify stud taper, mounting-hole spacing, and bolt-in orientation before installation. Because this is a non-greaseable assembly, inspect the dust boot and surrounding suspension components during service. Delphi TC2048 should be installed with the correct torque procedure and a professional alignment after replacement.
Quality Assurance
Delphi subjects its OE-style steering components to extreme temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. Delphi TC2048 is built to support OE-level performance expectations for the front upper suspension on the Dodge D50.
