Installation Notes and Tips

Fits 2002-2005 Honda Civic, front lower. Fits 2002-2004 Acura RSX, front lower. Press-in installation requires proper suspension service tools and careful removal of the original joint from the control arm. Verify stud taper, thread pitch, and mounting depth before final assembly. Use the included castle nut and cotter pin during installation, and confirm all fasteners are torqued to the vehicle manufacturer’s specifications.

Quality Assurance

Delphi tests steering and suspension components across extreme temperature and corrosion conditions, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. Delphi TC5638 is built as a standard replacement part with OE-oriented dimensional and material validation for consistent fit and function.
