Installation Notes and Tips

Installation of the Delphi TC5574 control arm and ball joint assembly requires removal of the existing front left lower suspension control arm. Since the assembly is pre-greased and includes bushings, no additional lubrication is necessary. Ensure all mounting bolts are torqued to manufacturer specifications. The ball joint’s press-in design requires proper seating during installation to avoid premature wear. Verify alignment after installation to maintain optimal handling and tire life.
