Installation Notes and Tips

Verify vehicle year, make, and model before installation. Inspect the steering rack, tie rod ends, and surrounding seals for wear before replacing the bellows. Confirm the bellows seats correctly on the rack and housing so the steering system remains protected after service.

Quality Assurance

Delphi validates steering components through temperature cycling and salt-spray exposure to support OE-level performance expectations. Part number TBR4528 is backed by Delphi’s OE-focused steering engineering approach.
