Installation Notes and Tips

Verify the vehicle’s front steering application before installation and compare the original boot dimensions to the listed measurements. Inspect the rack, tie rod ends, and clamps for wear or damage before fitting the new bellows. Delphi TBR5028 is a specific-fit replacement, so correct vehicle identification is important for proper sealing and steering travel.

Quality Assurance

Delphi subjects its steering components to OE-focused validation, including extreme temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. These checks support durability in harsh road and weather conditions while maintaining OE-style fit and material performance.
