Installation Notes
Verify front right placement before installation and compare the original bellows to Delphi TBR4313 for length, diameter, and end fitment. Inspect the steering rack, tie rod ends, and surrounding components for wear or damage before reassembly. Proper alignment checks are recommended after steering component service.
Quality Assurance
Delphi subjects steering components to extreme temperature testing below -40 C and above 120 C, along with 720 hours of salt spray exposure, to evaluate durability in demanding conditions. The brand’s OE-focused testing and material validation support consistent performance for Subaru steering applications.
